1 Scope

NOTE This standard governs the electric vehicle supply equipment as a listed product and the work that puts it into service: its rating, its enclosure, its connector and cable, its connection to the branch circuit, the load management and the network it participates in, the way a driver is authorized and charged, the parking spaces provisioned for it now and later, its mounting, its commissioning, and its identification. (1.1)
NOTE Electric vehicle supply equipment is the conductors, the connectors, the personnel protection, and the control electronics between the premises wiring and the vehicle; AC Level 1 and Level 2 equipment passes alternating current to the charger on board the vehicle, and DC fast charging equipment contains the charger and delivers direct current to the battery, which is why the two are listed to different standards and sized in different units. (1.2)
NOTE The values that differ from one unit to the next, including the rated output, the mounting, and the parking spaces each unit serves, live on the electrical drawings and the equipment schedules; the datasheet of this standard carries the policy that applies to every unit on the project unless a drawing states otherwise for a location. (1.3)

3 Submittals

3.1 Action Submittals

3.1.1 The Contractor shall submit the following for review before any charging equipment is procured:
  • product data for each unit type, identifying the manufacturer, the catalog designation, the listing standard and the listing agency, the input voltage and the number of phases, the rated output current or power, the number of ports and the output available per port with every port in use, the connector type on each cable, the cable length, the enclosure type, and the operating temperature range
  • product data for the energy management system, where one is furnished, identifying its listing, the maximum load it enforces, how it is set, how its settings are restricted, and what it does when it loses communication with the units it controls
  • network and communication data identifying the connectivity media furnished, the charging protocol version and its certification, the vehicle communication and grid interfaces furnished, and the security profile supported
  • authorization, fee collection, and energy measurement data, including the weights-and-measures certification where a fee based on the energy delivered is charged
  • shop drawings for each mounting condition giving the mounting height, the anchorage, the raceway entries, the location of the disconnecting means, the working space, and the clearance to the parking space and the access aisle
  • the plan of the charging spaces showing each EVSE-installed, EV-ready, and EV-capable space, each accessible charging space and its access aisle, and the reach of each cable to a vehicle inlet in the spaces it serves
  • the manufacturer's statement that the connector, the cable, and the cable management furnished are covered by the listing of the unit

☑ Product data for each unit type
☑ Energy management system data
☑ Network, protocol, and interface data
☐ Authorization, fee collection, and energy measurement data
☑ Mounting shop drawings
☑ Charging space plan with cable reach
☐ Listing coverage statement for connector, cable, and cable management
3.1.2 Charging equipment shall not be procured until the product data covering it has been reviewed and returned.
NOTE The charging space plan is the submittal that catches the error the product data cannot show: a unit whose cable reaches the inlet on one side of a vehicle but not the other, or a pedestal set where a vehicle in the adjacent space blocks the access aisle, is discovered on this plan or discovered after the concrete is poured. (3.1.3)

3.2 Informational Submittals

3.2.1 The Contractor shall submit the following with or before the action submittals:
  • the qualifications of the installing contractor and of the electricians who will install the equipment, as Quality Assurance requires
  • the manufacturer's installation instructions, including the mounting, the anchorage, the torque values, the conductor sizes the terminals accept, and the working space the listing requires
  • the commissioning plan, listing each test to be performed on each unit and on the energy management system, the instrument or the vehicle that will be used, and the acceptance criterion for each
  • correspondence with the serving utility confirming the service capacity available for the charging load, where the drawings indicate a new or an upgraded service

NOTE The back-office transfer is the closeout item an Owner discovers it is missing a year later, when the installer's account is the only administrator of the network and the installer is gone; the administrator role is transferred, not shared, before acceptance. (3.3.2)

4 Quality Assurance

4.1 Listing and Labeling

4.1.1 AC Level 1 and Level 2 charging equipment shall be listed to UL 2594, and DC fast charging equipment shall be listed to UL 2202.
4.1.2 Every unit shall incorporate a personnel protection system listed to UL 2231-1 and UL 2231-2 as part of the unit.
4.1.3 Connectors, vehicle couplers, and attachment plugs shall be listed to UL 2251 and shall be furnished as part of the listed unit.
4.1.4 Bidirectional charging equipment shall be listed to UL 9741, and where it exports power to the premises wiring it shall also be listed to UL 1741 for the interconnection function it performs.
4.1.5 An energy management system that limits the load of charging equipment shall be listed to UL 916 or shall be listed as part of the charging equipment it controls.
NOTE The listing covers the unit as a complete assembly, with the connector, the cable, the cable management, and the mounting the manufacturer evaluated with it; a cable assembly from another source or a field-modified mounting removes the unit from the condition under which it was listed. (4.1.6)
4.1.7 No unit shall be modified in the field in a manner that voids its listing, and a damaged connector or cable shall be replaced only with the assembly the manufacturer lists for that unit.

4.2 Installer Qualifications

4.2.1 The charging equipment shall be installed by the installer indicated in the datasheet.
Installer Qualificationradio
● Licensed electrical contractor
○ Licensed electrical contractor whose electricians on this work hold an electric vehicle infrastructure training certification accepted by the Authority Having Jurisdiction or the funding program
NOTE A licensed electrical contractor is the installer of every charging unit on most projects, which is why it is the default; the training certification is required by 23 CFR Part 680 on federally funded installations and by some state and utility incentive programs, and it is selected where the project is funded under one of those programs or where the Owner wants the installer trained on the commissioning of networked equipment as well as its wiring. (4.2.2)
4.2.3 Each electrician who terminates or commissions a unit shall have been instructed in the manufacturer's installation and commissioning procedure for that unit type.

4.3 Source Limitation

4.3.1 The limitation on the sources of the charging equipment shall be as indicated in the datasheet.
Source Limitationradio
○ All charging equipment from one manufacturer
○ All charging equipment of each type from one manufacturer
○ No source limitation
NOTE One manufacturer across the project gives the Owner one spare parts inventory, one service contact, and one network portal, and it limits competition to the manufacturers that make every type the project needs, which few do where DC fast charging and Level 2 are both present; one manufacturer per type keeps the spares and the service common among the units that are alike while letting each type come from the maker that builds it; no limitation opens every unit to the lowest bidder and leaves the Owner to manage as many portals and part numbers as there are makers. (4.3.2)
4.3.3 Where the energy management system is furnished separately from the charging equipment, the system manufacturer shall confirm in writing that it has tested its system with the unit types furnished, and the confirmation shall be included with the action submittals.

4.4 Regulatory Requirements

4.4.1 The installation shall comply with the edition of NFPA 70 adopted with Adopted Building CodeAdopted Building CodeParameterEach project supplies its own value.adopted-building-code and with the amendments of the Authority Having Jurisdiction.
4.4.2 Where the installation is funded in whole or in part under the National Electric Vehicle Infrastructure program, the equipment, the network, the payment methods, and the installer shall comply with 23 CFR Part 680 in addition to this standard.
4.4.3 Where a fee based on the energy delivered is charged to the driver, the energy measuring system of each unit shall be certified under NIST Handbook 44 Section 3.40 by the type-evaluation program the state has adopted, and the unit shall carry the certification mark.

5 Environmental and Service Conditions

5.1 Enclosure Type

5.1.1 The enclosure type of the charging equipment shall be as indicated in the datasheet.
Enclosure Type per NEMA 250select
Type 1
Type 3R
Type 4
Type 4X
NOTE This product departs from the Type 1 convention of indoor electrical equipment, because the installed location of charging equipment on most projects is a parking lot or an open parking structure that follows the outdoor weather, and the manufacturers build for that location: nearly every listed Level 2 and DC fast charging unit on the market carries a Type 3R or Type 4 enclosure from the factory, and a unit rated Type 1 is a dedicated indoor product that is offered by few makers. Type 3R is the rating most units carry and the rating an outdoor location requires, which is why it is the default; Type 1 is selected for a unit on the wall of a conditioned fleet garage or a dry interior where a lower-cost indoor unit is wanted; Type 4 is gasketed against hose-directed water and is the rating of a unit in a wash bay or a unit the Owner pressure-washes; Type 4X adds corrosion resistance and is the rating of a coastal lot, a parking structure treated with de-icing salt, or an industrial site with chemical vapor. (5.1.2)
5.1.3 The enclosure shall comply with UL 50E and NEMA 250 for the type selected, and the type shall be marked on the unit.
5.1.4 A unit installed outdoors, or in a parking structure open to the weather, shall have an enclosure of Type 3R, Type 4, or Type 4X.
5.1.5 A unit installed where it is subject to hose-directed water or wash-down shall have an enclosure of Type 4 or Type 4X.
5.1.6 A unit installed where the atmosphere carries salt, de-icing chemical, chemical vapor, or another corrosive agent, including a coastal site and a parking structure where de-icing salt is tracked in, shall have a Type 4X enclosure.
5.1.7 Where the enclosure type these clauses require exceeds the datasheet selection at an installed location, the higher type shall be furnished at that location and the conflict reported to the Engineer of Record before procurement.
5.1.8 Raceway entries into a Type 3R, Type 4, or Type 4X enclosure shall be made only with fittings listed for the enclosure type and only at the entry locations the manufacturer provides.

5.2 Ambient Temperature and Altitude

5.2.1 A unit installed outdoors or in an unconditioned parking structure shall be listed for operation across the range from Site Ambient Temperature MinimumSite Ambient Temperature MinimumParameterEach project supplies its own value.site-ambient-temperature-minimum to Site Ambient Temperature MaximumSite Ambient Temperature MaximumParameterEach project supplies its own value.site-ambient-temperature-maximum.
5.2.2 Where a unit reduces its output above a stated ambient temperature, the manufacturer shall state the temperature and the reduced output in the product data, and the output at Site Ambient Temperature MaximumSite Ambient Temperature MaximumParameterEach project supplies its own value.site-ambient-temperature-maximum shall be not less than the rated output indicated for that unit.
5.2.3 DC fast charging equipment installed above the altitude rating basis of its listing shall be derated for AltitudeAltitudeParameterEach project supplies its own value.altitude in accordance with the manufacturer's published correction factors, and the derated output shall be stated in the product data.
NOTE A charger that derates in the afternoon heat of the lot it stands in delivers less than the schedule promised at exactly the hour it is most used, which is why the output is confirmed at the site's design temperature rather than at the catalog's 25 °C. (5.2.4)

5.3 Seismic Anchorage

5.3.1 Pedestal-mounted units and floor-standing DC fast charging cabinets shall be anchored in accordance with the seismic provisions of Adopted Building CodeAdopted Building CodeParameterEach project supplies its own value.adopted-building-code for Seismic Design CategorySeismic Design CategoryParameterEach project supplies its own value.seismic-design-category, and the anchorage shall be that the manufacturer's installation instructions give for the unit as furnished.
5.3.2 Where Seismic Design CategorySeismic Design CategoryParameterEach project supplies its own value.seismic-design-category requires the anchorage to be designed, the anchorage design shall be submitted with the mounting shop drawings.

6 Charging Equipment Type and Rating

6.1 Charging Equipment Type

6.1.1 The type of the charging equipment shall be as indicated in the datasheet.
Charging Equipment Typeradio
○ AC Level 1
● AC Level 2
○ DC fast charging
NOTE AC Level 1 equipment operates at 120 V and delivers up to about 1.9 kW, which adds a few miles of range per hour and suits a vehicle parked for a shift or overnight where the lowest installed cost per space matters more than the charging rate; AC Level 2 equipment operates at 208 V or 240 V and delivers from 3 kW to 19 kW, which charges most vehicles fully in the hours they are parked at a workplace, a residence, or a destination, and it is the type on the large majority of building projects, which is why it is the default; DC fast charging equipment contains the charger and delivers from tens of kilowatts to over a megawatt of direct current, which charges a vehicle in minutes rather than hours, and it is selected for a fleet depot, a public site where drivers stop briefly, or a corridor site, at an installed cost and a utility demand many times that of Level 2 equipment. A project that furnishes more than one type records the type of each unit on the equipment schedules. (6.1.2)
6.1.3 The input voltage and the number of phases of each unit shall be as indicated on the electrical equipment schedules.

6.2 Ports per Unit

6.2.1 The number of ports on each unit shall be as indicated in the datasheet.
Ports per Unitradio
○ Single-port
○ Dual-port
NOTE A single-port unit serves one space and is the unit of a residence, a reserved fleet space, and a wall where each space has its own unit; a dual-port unit stands between two spaces and serves both from one pedestal and one or two circuits, which halves the pedestal count and the raceway runs in a lot, at the cost of a unit that is out of service for two spaces when it fails. Neither is the norm across projects, so the field carries no default. (6.2.2)
6.2.3 Where a dual-port unit shares its rated output between its ports, the output available to each port with both ports in use shall be stated in the product data, and the shared output shall satisfy the rated output indicated for the unit.

6.3 AC Rated Output Current

6.3.1 The rated continuous output current of each AC Level 2 unit shall be as indicated in the datasheet.
AC Level 2 Rated Output Current per Portrange
A
121620243240486480
Per drawings — the electrical equipment schedules (deferred by default)
NOTE The output current fixes the branch-circuit rating, the conductor size, and the charging rate, and it is set per unit by the vehicles the space serves and the capacity the service has to give, so it is stated on the equipment schedules; the datasheet records the current only where one rating applies across the project. The output power in kilowatts follows from the output current and the supply voltage, so it is not stated separately: a 32 A unit delivers 6.6 kW at 208 V and 7.7 kW at 240 V, and a 48 A unit delivers 10 kW and 11.5 kW. (6.3.2)
6.3.3 A unit whose output current is adjustable shall be set to the rated output indicated for that unit, and the adjustment shall be accessible only with a tool, a password, or behind a sealed cover, in accordance with NFPA 70 625.42.

6.4 DC Rated Output Power

6.4.1 The rated output power of each DC fast charging unit shall be as indicated in the datasheet.
DC Fast Charging Rated Output Power per Dispenserrange
kW
2025305060759010012015018020024025030035040050060075010001200
Per drawings — the electrical equipment schedules (deferred by default)
NOTE The output power of a DC unit is set by the vehicles it serves and the utility capacity at the site, from the 20 kW to 60 kW unit that tops up a fleet overnight, through the 150 kW to 350 kW unit of a public corridor site, to the megawatt-class unit of a truck depot, and it is stated on the equipment schedules with the input it draws. (6.4.2)
6.4.3 Where a DC unit is furnished as a power cabinet feeding separate dispensers, the power available at each dispenser with every dispenser in use shall be stated in the product data, and the DC output voltage range of each dispenser shall cover the battery voltages of the vehicles the project is designed to serve.
NOTE The output voltage range matters as much as the power rating, because a dispenser whose maximum output voltage is below the pack voltage of a vehicle delivers that vehicle a fraction of its rated power however large its nameplate. (6.4.4)

6.5 Power Flow Direction

6.5.1 The power flow capability of the charging equipment shall be as indicated in the datasheet.
Power Flow Directionradio
● Unidirectional
○ Bidirectional
NOTE Unidirectional equipment delivers power to the vehicle only and is the equipment on nearly every project, which is why it is the default; bidirectional equipment also draws power from the vehicle battery to the premises or the grid, which lets a fleet or a building use parked vehicles as storage, and it requires a vehicle that supports export, an interconnection with the utility, and an equipment listing and a protocol that few units carry. (6.5.2)
6.5.3 Where bidirectional equipment is furnished, its export function shall comply with NFPA 70 625.48 and Article 705, the interconnection shall be approved by the serving utility before the equipment is energized, and the export shall be disabled until that approval is obtained.

7 Connectors and Cable

7.1 AC Connector

7.1.1 The vehicle connector furnished on AC Level 1 and Level 2 equipment shall be as indicated in the datasheet.
AC Vehicle Connectorradio
○ SAE J1772
○ SAE J3400
○ SAE J1772 and SAE J3400, one cable of each on every port
NOTE The AC connector is a live market decision in 2026: the vehicles on the road carry the SAE J1772 inlet in the large majority, while nearly every vehicle maker selling in North America has adopted the SAE J3400 inlet for new models, and the two inlets accept each other's connector through a passive adapter. A J1772 connector serves the existing fleet without an adapter and the new fleet with the adapter the vehicle makers supply with those vehicles; a J3400 connector serves the new fleet without an adapter and the existing fleet only through an adapter the driver has to own; both connectors on every port serve every vehicle without an adapter at the cost of a second cable assembly and a heavier cable management. No connector is the norm across projects while the fleet turns over, so the field carries no default. (7.1.2)
7.1.3 Where a connector of each type is furnished on one port, the two cables shall share the port's rated output and shall not deliver power to two vehicles at once unless the unit is listed for that operation.

7.2 DC Connectors

7.2.1 The vehicle connectors furnished on each DC fast charging dispenser shall be as indicated in the datasheet.
DC Vehicle Connectors per Dispensercheckbox
☐ CCS1 combined charging connector per SAE J1772
☐ SAE J3400 DC connector
☐ CHAdeMO connector
☐ Megawatt charging connector per SAE J3271
NOTE The CCS1 connector is the DC connector on the installed light-duty fleet other than one maker's vehicles, and it is the connector 23 CFR Part 680 requires on every federally funded port; the SAE J3400 connector is the DC connector of that maker's vehicles and of the new models adopting its inlet, and a dispenser that carries both serves the whole light-duty fleet; the CHAdeMO connector serves a shrinking population of older vehicles and is furnished where the Owner's fleet includes them; the megawatt charging connector serves heavy-duty trucks and buses at currents the light-duty connectors cannot carry. The connectors are checked independently because a dispenser carries any combination of them, and no combination is the norm across projects. (7.2.2)
7.2.3 Where a dispenser carries more than one connector, the product data shall state whether the connectors deliver rated output simultaneously or share it, and a dispenser that shares output shall be scheduled for the spaces it serves on that basis.
7.2.4 A liquid-cooled cable shall be furnished where the rated output current of the connector exceeds the current a passively cooled cable of a weight a driver can handle is listed to carry.

7.3 Cable Length

7.3.1 The length of the output cable from the unit to the vehicle connector shall be as indicated in the datasheet.
Output Cable Lengthrange
ft
1040
NOTE The cable has to reach the inlet of a vehicle parked nose-in or backed-in, whose inlet is on either fender or at the nose, from a unit set to one side of the space, and a cable that reaches every inlet in a two-space layout is near the 25 ft limit NFPA 70 sets for a cable without a cable management system; a shorter cable is lighter, costs less, and lies on the ground less, and it serves a reserved space whose vehicle always parks the same way. No length is the norm, because it follows from the unit's position relative to the spaces it serves, so the field carries no default. (7.3.2)
7.3.3 A cable longer than 25 ft shall be furnished only with a cable management system listed with the unit, in accordance with NFPA 70 625.17.
7.3.4 The cable of each unit shall reach the vehicle inlet at either side and at the nose of a vehicle parked in each space the unit serves without crossing an adjacent space, an access aisle, or a pedestrian walkway, and the reach shall be shown on the charging space plan.

7.4 Cable Management

7.4.1 The cable management furnished with each unit shall be as indicated in the datasheet.
Cable Managementselect
Connector holster on the unit
Connector holster with a cable hook or cradle on the unit or pedestal
Spring retractor or overhead reel
Pivoting cable management arm
NOTE A holster on the unit parks the connector off the ground and is furnished on every unit, which is why it is the default; a hook or cradle takes the slack of a long cable so it does not lie in the drive aisle and is added where the cable exceeds the reach a holster alone keeps off the ground; a retractor or reel lifts the whole cable clear of the ground when the connector is holstered and is the system a ceiling-mounted unit in a parking structure uses; a pivoting arm carries the cable over the vehicle from a pedestal and is used where the cable is heavy, as at a liquid-cooled DC dispenser, or where it must not touch the ground at all. (7.4.2)
7.4.3 The cable management shall keep the connector and the cable off the parking surface when the connector is holstered, and the connector shall be holstered within the reach range the accessible charging space clauses of this standard require.

8 Connection to the Branch Circuit

8.1 Connection Method

8.1.1 The connection of each unit to its branch circuit shall be as indicated in the datasheet.
Connection Methodradio
● Hardwired
○ Cord-and-plug
NOTE A hardwired unit is connected to the branch circuit at its terminals, carries the full output its listing permits, and cannot be unplugged or stolen without tools, and it is the connection of nearly every unit on a commercial, institutional, or multifamily project, which is why it is the default; a cord-and-plug unit plugs into a receptacle, which lets the unit be replaced or taken along without an electrician, limits the output to what the plug configuration and NFPA 70 625.44 permit, and is the connection of many residential units and of an EV-ready space whose receptacle is already in place. (8.1.2)
8.1.3 A cord-and-plug connection shall be used only where NFPA 70 625.44 permits it for the rating of the unit, and the power-supply cord shall be the cord furnished and listed with the unit.
8.1.4 The attachment plug of a cord-and-plug-connected unit shall mate with the receptacle furnished under Wiring DevicesWiring DevicesResolves to the current adopted revision.sync/wiring-devices at that outlet, and the configuration, the ground-fault protection, and the mounting of that receptacle are governed by that standard.
NOTE The receptacle is a wiring device and the unit that plugs into it is charging equipment, so the two are governed by two standards: the configuration of the receptacle at each outlet is stated on the electrical plans under the wiring device standard, and the unit furnished here carries the plug that mates with it. A receptacle at an EV-ready space that has no unit yet is governed entirely by the wiring device standard. (8.1.5)

8.2 Branch-Circuit Rating

8.2.1 Each unit shall be supplied by a branch circuit whose overcurrent device is rated not less than 125% of the maximum load of the unit, in accordance with NFPA 70 625.41, and the device rating shall be as indicated on the panel schedules.
8.2.2 Each unit rated more than 16 A or more than 120 V shall be supplied by an individual branch circuit that serves no other load, in accordance with NFPA 70 625.40, unless an energy management system selected under this standard controls the units sharing the circuit as NFPA 70 625.42 permits.
NOTE Charging equipment is a continuous load, so a unit rated 32 A requires a 40 A circuit and a unit rated 48 A requires a 60 A circuit; specifying a device equal to the unit's rating is the most common error in a charging circuit design, and it fails inspection. (8.2.3)
NOTE The overcurrent device is furnished in the panelboard under PanelboardsPanelboardsResolves to the current adopted revision.sync/panelboards, the conductors are sized and installed under Conductors And CablesConductors and CablesResolves to the current adopted revision.sync/conductors-and-cables, and the raceway is installed under Raceways And ConduitRaceways and ConduitResolves to the current adopted revision.sync/raceways-and-conduit; this standard states the sizing rule the unit imposes on them and nothing else about them. (8.2.4)
8.2.5 The maximum load of a unit whose output is adjustable shall be the output it is set to under this standard, and the maximum load of a unit controlled by an energy management system shall be the load that system enforces for it.

8.3 Disconnecting Means

8.3.1 Each unit rated more than 60 A or more than 150 V to ground shall be provided with a disconnecting means that is readily accessible, located within sight of the unit, and lockable in the open position, in accordance with NFPA 70 625.43.
8.3.2 The disconnecting means shall be an enclosed switch or circuit breaker furnished under Enclosed Switches And DisconnectsEnclosed Switches and DisconnectsResolves to the current adopted revision.sync/enclosed-switches-and-disconnects, rated for the unit's input, and in an enclosure of the type this standard requires for the location.
NOTE A DC fast charging unit nearly always crosses the 60 A threshold and a 480 V unit always crosses the 150 V threshold, so a disconnect at the unit is the rule for DC equipment and the exception for Level 2 equipment, whose branch breaker in the panelboard is its disconnecting means. (8.3.3)

8.4 Personnel Protection and Ventilation

8.4.1 The personnel protection system of each unit shall interrupt the output on a ground fault and shall be the system listed to UL 2231-2 within the unit, and the unit shall not be supplied through an additional ground-fault circuit-interrupter device unless NFPA 70 625.54 requires one at a receptacle.
8.4.2 A unit installed indoors shall be of a type listed and marked as not requiring ventilation, in accordance with NFPA 70 625.52, unless the mechanical drawings provide the ventilation that section requires for a unit marked as requiring it.
8.4.3 The equipment grounding of each unit and the bonding of a metal pedestal shall comply with Grounding And BondingGrounding and Bonding for Electrical SystemsResolves to the current adopted revision.sync/grounding-and-bonding.

9 Load Management

9.1 Load Management Strategy

9.1.1 The load management applied to the charging equipment shall be as indicated in the datasheet.
Load Management Strategyradio
○ None
○ Local power sharing among the units on one branch circuit or feeder
○ Networked energy management system
NOTE With no load management every unit is supplied at its full rating on its own circuit, and the feeder, the panelboard, and the service are sized for the sum of them, which is the simplest installation and the one that fits where the unit count is small; local power sharing lets a group of units on one circuit divide its capacity among the vehicles plugged in, by a setting at the units or by communication among them with no network, which lets more units be installed on a given circuit than their ratings allow; a networked energy management system limits the aggregate demand of every unit it controls to a setpoint, which NFPA 70 625.42 and Article 750 let the feeder and the service be sized to, and it is the difference between a large lot and a service upgrade. Which is wanted depends on the unit count against the capacity available, so the field carries no default. (9.1.2)
9.1.3 Where load management other than none is selected, the feeder and service load calculation under NFPA 70 Article 220 shall use the load the energy management system or the power sharing enforces, and the calculation shall be as indicated on the one-line diagram.

9.2 Energy Management System Operation

9.2.1 Where a networked energy management system is selected, it shall limit the aggregate demand of the units it controls to a setpoint not exceeding the rating of the feeder or the branch circuit that supplies them, and the setpoint for each shall be as indicated on the one-line diagram.
9.2.2 The energy management system shall reduce the units it controls to an output whose sum does not exceed the setpoint within the time its listing requires when a unit it controls starts, and shall not depend on the vehicle to limit its own draw.
9.2.3 On loss of communication between the energy management system and a unit it controls, the unit shall reduce its output to the fallback value the system is set to, and the fallback values of every unit on a feeder shall sum to not more than the feeder rating.
9.2.4 The setpoint and the fallback values shall be accessible only to an authorized user with a tool, a password, or a key, and the settings as left shall be recorded in the closeout submittals.
9.2.5 Each feeder and panelboard whose rating relies on the energy management system shall be marked with the maximum charging load the system permits, in accordance with NFPA 70 625.42 and 750.30, with a label furnished under Electrical IdentificationWiring System IdentificationResolves to the current adopted revision.sync/electrical-identification.
NOTE The fallback is the whole safety of a feeder sized below the sum of the units on it: a unit that returns to full output when it loses the network overloads the feeder it was installed to protect, which is why the fallback is set at the unit, recorded, and tested. (9.2.6)

10 Networking and Communications

10.1 Network Connectivity

10.1.1 Whether the charging equipment is connected to a charging network shall be as indicated in the datasheet.
Network Connectivityradio
○ Non-networked
○ Networked
NOTE A non-networked unit charges any vehicle plugged into it, costs less, needs no service subscription, and reports nothing, and it is the unit of a residence and of a fleet or employee lot where no one is billed and no one needs to see it from a desk; a networked unit reports its status and its energy to a back office, authorizes drivers, collects fees, receives firmware, and is the unit of a public site, a billed tenant lot, and any installation under an energy management system that uses the network to control it. Neither is the norm across projects, so the field carries no default. (10.1.2)
10.1.3 The connectivity media furnished on networked units shall be as indicated in the datasheet.
Network Connectivity Mediacheckbox
☐ Ethernet
☐ Wi-Fi
☐ Cellular
NOTE Ethernet is the most reliable medium and needs a cable to every unit or to a gateway at each pedestal group, installed under the structured cabling standard; Wi-Fi needs no cable and depends on the Owner's network reaching the parking area, which it often does not; cellular needs neither and carries a monthly cost per unit, and it fails in a below-grade parking structure without a signal. Units commonly carry two media so one backs up the other. (10.1.4)
10.1.5 Where cellular connectivity is furnished, the Contractor shall verify the signal strength of the carrier at each unit location before the unit is mounted and shall report a location without usable signal to the Engineer of Record.
10.1.6 Where Ethernet connectivity is furnished, the horizontal cabling to each unit or gateway shall comply with Structured CablingStructured Cabling SystemsResolves to the current adopted revision.sync/structured-cabling.
10.1.7 Networked units shall communicate with the back office over an encrypted connection, shall authenticate the back office, and shall accept firmware updates over the network.

10.2 Charging Protocol Version

10.2.1 Networked units shall communicate with the charging network back office by the Open Charge Point Protocol version indicated in the datasheet.
Open Charge Point Protocol Versionselect
OCPP 1.6J
OCPP 2.0.1
OCPP 2.1
NOTE OCPP 1.6J is the version most charging networks in operation were built on, and a unit that speaks it connects to the widest set of existing back offices; OCPP 2.0.1 adds device management, security profiles, and the messages that carry ISO 15118 vehicle communication and smart charging, and it is the version 23 CFR Part 680 requires on federally funded installations; OCPP 2.1 adds bidirectional power transfer and distributed energy resource control and is supported by few back offices at the time of writing. The version follows the back office the Owner will use and the features the project needs, so the field carries no default. (10.2.2)
10.2.3 Networked units shall be certified to the protocol version selected under the Open Charge Alliance certification program where a certification exists for that version, and the certificate shall be included with the action submittals.
10.2.4 The Owner shall be able to redirect each networked unit to a different charging network back office at the end of the network service term, without replacing hardware, and the manufacturer shall state in the product data how the back office address is changed.
NOTE A unit locked to one network for its life is a unit the Owner replaces when the network's pricing changes, which is why the ability to redirect it is required even where the Owner intends to stay with the network it starts on. (10.2.5)

10.3 Vehicle Communication and Grid Interfaces

10.3.1 The vehicle communication and grid interfaces furnished on the charging equipment shall be as indicated in the datasheet.
Vehicle Communication and Grid Interfacescheckbox
☐ ISO 15118 high-level communication with Plug and Charge
☐ OpenADR 2.0b demand response client
☐ Local interface to the building energy management system
☐ Smart charging under the charging protocol
NOTE ISO 15118 communication lets the vehicle identify itself and authorize the session without a card or an app, which is Plug and Charge, and it is the channel bidirectional charging uses; an OpenADR client lets the utility's demand response program curtail the charging load during an event in exchange for a tariff or an incentive; a local interface lets the building energy management system read and limit the charging load alongside the building's other loads without going through the charging network; smart charging under the protocol lets the back office schedule and limit charging centrally. Each is checked independently because a unit carries any combination of them. (10.3.2)

10.4 Network Service Term

10.4.1 The charging network service, including the back-office subscription, the cellular data where cellular connectivity is furnished, and the driver support line, shall be furnished for the term indicated in the datasheet, commencing at substantial completion.
Network Service Term Furnishedrange
Not less than
years
010
NOTE The service term furnished with the installation is the period the Owner pays nothing further to keep the units networked; a term of zero records that the Owner contracts for the service itself from the first day, a term of one to three years is what most networked installations include, and a longer term is bought where the project is funded under a program that requires the network to be maintained for that period. No term is the norm, so the field carries no default. (10.4.2)
10.4.3 The network service agreement shall name the Owner as the account holder, shall state the fees that apply after the term furnished, and shall be delivered with the closeout submittals.

11 Access, Authorization, and Metering

11.1 Authorization Methods

11.1.1 The methods by which a driver is authorized to start a charging session shall be as indicated in the datasheet.
Authorization Methodscheckbox
☐ Open access, no authorization
☐ RFID card or key fob
☐ Mobile application or QR code
☐ Contactless payment card reader
☐ Plug and Charge under ISO 15118
NOTE Open access lets anyone who plugs in charge, which is the arrangement of a residence, an employee lot with no billing, and a free amenity; an RFID card or fob authorizes a known population and is what a fleet and a tenant lot use; a mobile application or QR code authorizes any driver who has or installs the network's application and is the usual public method; a contactless payment card reader authorizes any driver with a bank card and no account, which 23 CFR Part 680 requires on federally funded ports; Plug and Charge authorizes the vehicle itself with no action by the driver and requires a vehicle and a unit that both support it. Public sites carry several methods so that no driver is turned away, and the methods are checked independently for that reason. (11.1.2)
11.1.3 Where a fee is charged, the unit or the network shall display the price before the session starts, and the fee structure, whether by energy, by time, by session, or any combination, shall be as the Owner directs in writing before commissioning.
11.1.4 A unit that requires a membership or a subscription as the only means of authorization shall not be furnished where 23 CFR Part 680 applies to the installation.

11.2 Energy Metering

11.2.1 The energy measurement furnished in each unit shall be as indicated in the datasheet.
Energy Measurement in the Unitselect
No energy measurement
Energy measurement for reporting, not certified
Revenue-grade energy measurement certified under NIST Handbook 44 Section 3.40
Derived — whether a fee based on the energy delivered is charged to the driver, and the weights-and-measures requirements of the state in which the project is located (by default)
NOTE Whether the unit must measure energy to a certified accuracy is fixed by the fee and by the state: a unit that charges by the kilowatt-hour in a state that has adopted Section 3.40 of Handbook 44 is a commercial measuring device under that state's weights-and-measures law and must carry the certification, a unit that charges by time or by session or charges nothing needs only the measurement its reporting requires, and a non-networked unit that bills no one needs none. The field records the consequence of those inputs rather than a preference, which is why it starts derived. (11.2.2)
NOTE Energy measurement in the unit serves the charging session and the driver's bill; the measurement of the charging load for the building's energy accounting or for tenant submetering is furnished under Electrical Power MonitoringElectrical Power Monitoring and MeteringResolves to the current adopted revision.sync/electrical-power-monitoring and is not a substitute for the certified measurement a fee requires. (11.2.3)

12 Charging Space Provisioning

12.1 Provisioning Tiers

NOTE The adopted codes provision parking spaces for charging in three tiers, named here as the codes name them: an EV-capable space has a raceway from the panelboard to a termination point at the space, with capacity and a breaker space reserved in the panelboard and no conductors installed; an EV-ready space has a complete branch circuit terminating in a receptacle or a junction box at the space and no charging unit; an EVSE-installed space has a complete, energized, and commissioned charging unit. (12.1.1)
12.1.2 The number of parking spaces provisioned at each tier shall be not less than Adopted Building CodeAdopted Building CodeParameterEach project supplies its own value.adopted-building-code and Adopted Energy CodeAdopted Energy CodeParameterEach project supplies its own value.adopted-energy-code require for the occupancy and the parking count of the project.
12.1.3 The spaces provisioned at each tier shall be as indicated on the electrical site plan.
NOTE The three tiers are confused on drawings and in permit reviews often enough that the plan is required to name the tier of each space: a space labeled "EV" with no tier is the space the inspector asks about. Provisioning at rough-in is inexpensive and provisioning after the slab is poured is not, which is why the codes require the raceway now for a unit that is installed later. (12.1.4)

12.2 EV-Capable Space Requirements

12.2.1 Each EV-capable space shall be served by a raceway installed under Raceways And ConduitRaceways and ConduitResolves to the current adopted revision.sync/raceways-and-conduit, continuous from the panelboard to a termination point at the space, capped at the space, and identified at both ends as reserved for electric vehicle charging.
12.2.2 The raceway serving each EV-capable space shall be sized for the conductors of a branch circuit of the rating indicated in the datasheet.

NOTE The codes state the capacity an EV-capable space is held for, which is a 40 A, 208 V or 240 V branch circuit in the model energy code and in most state codes, and some editions permit a lower per-space capacity where an energy management system will share it; the raceway and the reserved panelboard capacity follow from that figure, which is why the field starts derived from the adopted codes rather than carrying a value. (12.2.3)
12.2.4 The panelboard serving each EV-capable space shall have a breaker space reserved for it and identified on the panel schedule as reserved for electric vehicle charging, and the breaker space and its identification are furnished under PanelboardsPanelboardsResolves to the current adopted revision.sync/panelboards.
12.2.5 The termination point of each EV-capable raceway shall be located where a wall-mounted or pedestal-mounted unit can later be installed within the reach of the spaces it is to serve, and shall be recorded on the record drawings.

12.3 EV-Ready Space Requirements

12.3.1 Each EV-ready space shall be served by a complete branch circuit of the rating indicated on the panel schedules, terminating in a receptacle or a junction box at the space.
12.3.2 The receptacle at an EV-ready space shall be furnished under Wiring DevicesWiring DevicesResolves to the current adopted revision.sync/wiring-devices, and a junction box at an EV-ready space shall be covered and identified as reserved for electric vehicle charging.

12.4 Accessible Charging Spaces

12.4.1 The number of accessible charging spaces shall be not less than the accessibility provisions of Adopted Building CodeAdopted Building CodeParameterEach project supplies its own value.adopted-building-code require, and the accessible charging spaces and their access aisles shall be as indicated on the site plan.
12.4.2 At an accessible charging space, the operable parts of the unit, including the connector in its holster, the display, the card reader, and every button, shall be between 15 in. and 48 in. above the surface from which they are reached, and a clear floor space of not less than 30 in. by 48 in. shall be provided at the unit, connected by an accessible route to the access aisle.
12.4.3 The cable of a unit serving an accessible charging space shall reach the vehicle inlet from the access aisle side of the space without crossing the access aisle in a manner that obstructs it.
NOTE The 2010 ADA Standards have no section written for charging equipment, so the operable parts, reach range, and clear floor space provisions of those standards apply to the unit as a fixed element, and the number of accessible charging spaces is set by the adopted building code, which in several states carries requirements written for charging spaces; the Access Board's design recommendations describe a layout that satisfies the standards and are the document reviewers compare a plan against. A charging space is not an accessible parking space and a project does not reduce its accessible parking count by providing accessible charging spaces. (12.4.4)
12.4.5 The striping and the signing of every charging space, including the accessible charging spaces and their access aisles, shall comply with Pavement MarkingsPavement Markings and Site SignageResolves to the current adopted revision.sync/pavement-markings.

13 Identification

13.1 Each unit shall carry the manufacturer's listing mark, its electrical ratings, and, for a unit installed indoors, the ventilation marking NFPA 70 625.52 requires, as applied by the manufacturer.
13.2 Each unit shall be labeled in the field with the designation of the panelboard and the circuit that supplies it, with a label furnished under Electrical IdentificationWiring System IdentificationResolves to the current adopted revision.sync/electrical-identification.
13.3 Each networked unit shall display, where a driver can read it before plugging in, the station identifier under which it is listed in the charging network and the means of authorization it accepts.
13.4 The disconnecting means of each unit, where one is furnished, shall be identified as the disconnect for that unit and shall carry the arc-flash warning label Electrical IdentificationWiring System IdentificationResolves to the current adopted revision.sync/electrical-identification requires.
13.5 Each EV-capable raceway termination and each EV-ready junction box shall be identified as reserved for electric vehicle charging, in lettering that survives the environment of the parking area.

14 Installation

14.1 Mounting and Location

14.1.1 The mounting of each unit shall be as indicated in the datasheet.
Unit Mountingselect
Wall-mounted
Pedestal-mounted
Ceiling-mounted
Per drawings — the electrical plans (deferred by default)
NOTE A unit on the wall of a garage or a parking structure is wall-mounted at the head of the space; a unit in an open lot stands on a pedestal at the head of the space or between two spaces; a unit in a parking structure where the walls are not at the spaces is mounted to the ceiling or the structure above with a retractor, which keeps the floor clear and the cable off the ground. The mounting follows the location, which is why it is stated on the electrical plans. (14.1.2)
14.1.3 A wall-mounted unit shall be anchored to the structure or to blocking with the fasteners the manufacturer's instructions give, and shall not be supported by the raceway.
14.1.4 A pedestal-mounted unit and a floor-standing cabinet shall be set on a cast-in-place foundation constructed under Concrete PadsConcrete Equipment PadsResolves to the current adopted revision.sync/concrete-pads or on the precast base the manufacturer furnishes and lists with the unit, with the top of the foundation not less than 4 in. above the finished parking surface, and anchored as the Seismic Anchorage clauses of this standard require.
14.1.5 Each unit shall be mounted at the height the manufacturer's instructions give, with the connector holster within the reach range the Accessible Charging Spaces clauses require at an accessible charging space and not more than 48 in. above the parking surface elsewhere.
14.1.6 A unit shall be located so that a vehicle parked in the space it serves, including its overhang beyond a wheel stop or a curb, does not strike it, and so that the open door of a parked vehicle does not strike it.
14.1.7 Working space in front of a DC fast charging cabinet and of every disconnecting means shall comply with NFPA 70 110.26 for the voltage and the condition of the space, and no parking space shall encroach on it.
14.1.8 Utility coordination for a new or an upgraded service to carry the charging load shall be complete under Electrical Service EntranceElectrical Service EntranceResolves to the current adopted revision.sync/electrical-service-entrance before DC fast charging equipment is ordered.

14.2 Vehicle Impact Protection

14.2.1 A pedestal-mounted unit, a floor-standing cabinet, and the disconnecting means of either, where located where a vehicle can strike it, shall be protected by a curb, a wheel stop, or bollards, as indicated on the site plan.
14.2.2 Bollards furnished to protect the equipment shall comply with Site Furnishings And BollardsSite Furnishings and BollardsResolves to the current adopted revision.sync/site-furnishings-and-bollards, and shall be set so that they do not reduce the clear floor space, the access aisle, or the reach of the cable at an accessible charging space.
NOTE A pedestal struck by a vehicle shears its anchors, parts its conductors at the base, and leaves a live stub in a parking lot, which is why the protection is a requirement of the unit's location and not a site furnishing added where a budget allows. (14.2.3)

14.3 Terminations and Entries

14.3.1 Every conductor termination in the unit shall be torqued to the manufacturer's published value with a calibrated torque tool, in accordance with NFPA 70 110.14(D), and the values applied shall be recorded in the commissioning report.
14.3.2 Where aluminum conductors are terminated in a unit, the terminals shall be listed for aluminum and the conductors prepared as the terminal listing requires.
14.3.3 Every raceway entry and every unused opening in the unit and its pedestal shall be closed with a fitting listed for the enclosure type, and the enclosure type shall be preserved at every entry.
14.3.4 The conductors and their terminations shall comply with Conductors And CablesConductors and CablesResolves to the current adopted revision.sync/conductors-and-cables, and the raceways shall comply with Raceways And ConduitRaceways and ConduitResolves to the current adopted revision.sync/raceways-and-conduit.

15 Testing and Commissioning

15.1 Field Tests

15.1.1 Each unit shall be tested after installation and before it is placed in service, and the tests performed shall be as indicated in the datasheet.
Field Testscheckbox
☑ Functional charging test at rated output
☑ Personnel protection trip test
☑ Network communication and back-office registration test
☐ Energy management system load-limit and fallback test
☐ Authorization and fee transaction test
☐ Accessible charging space reach and clear floor space verification
NOTE The functional test proves the unit delivers what the schedule says at the location it stands in; the personnel protection test proves the device that protects a driver trips on a real fault and not only on its self-test; the network test proves the unit is registered under its own identifier and reports to the Owner's account; the load-limit test proves the feeder sized below the sum of the units is protected, and is the test that cannot be skipped where an energy management system is furnished; the transaction test proves a driver is billed what the price display says; the reach verification proves the accessible space works for the person it was laid out for. Most projects default to the first three and add the others where the feature is furnished. (15.1.2)
15.1.3 The functional charging test shall be performed with a vehicle or with a test instrument that emulates the vehicle's control pilot and proximity states and draws current, and the measured output at each port shall be not less than the rated output indicated for the unit.
15.1.4 The personnel protection trip test shall apply a ground-fault current with an instrument that emulates a fault in the output circuit, and shall confirm that the unit interrupts the output within the time its listing requires and recloses as its listing provides.
15.1.5 Where an energy management system is furnished, the load-limit test shall start every unit under its control at once with vehicles or instruments drawing full current and shall confirm that the aggregate demand is held at or below the setpoint; the fallback test shall then interrupt communication to a unit and confirm that it reduces its output to the recorded fallback value.
15.1.6 A unit that fails any test shall not be placed in service, the failure shall be corrected and the test repeated, and the cost of the correction and of every repeated test shall be borne by the Contractor.
15.1.7 The Contractor shall conduct a training session for the Owner's staff before substantial completion covering the operation of the units, the administration of authorization and pricing in the network portal, the reading of the energy management system settings, and the reset of a faulted unit.

16 Delivery, Storage, and Handling

16.1 Each unit shall be delivered in the manufacturer's packaging with the listing marks intact, and shall be inspected at receipt for damage and for conformance with the reviewed submittal.
16.2 Units shall be stored indoors in a dry space within the manufacturer's published storage temperature range, off the floor, and protected from dust, paint, and construction debris until they are installed.
16.3 A unit installed before the parking surface and the site work are complete shall be protected from impact, from construction traffic, and from the dust and debris of the remaining work until substantial completion.
16.4 A unit with a cracked enclosure, a damaged connector, a cut or crushed cable, or a broken or missing listing mark shall be rejected and replaced at no cost to the Owner.

17 Warranty

17.1 The manufacturer shall warrant each unit, including its connector and cable assembly, its cable management, its display, and its communication electronics, against defects in materials and workmanship for the period indicated in the datasheet, measured from the date of substantial completion.
Manufacturer's Warranty Periodrange
Not less than
years
123510
NOTE Manufacturers warrant charging equipment for periods that run from one year to five across the market, with longer terms sold as an extension, and the period an Owner asks for depends on whether it maintains its own equipment, on whether a funding program requires a term, and on how long it expects the connector standard to stay current; no period is the norm, so the field carries no default. The connector and cable assembly is the part that fails first and the part some manufacturers exclude as a wear item, which is why the warranty is required to include it. (17.2)
17.3 The warranty coverage shall be as indicated in the datasheet.
Warranty Coverageradio
○ Parts
○ Parts and on-site labor
NOTE A parts warranty ships a replacement and leaves the Owner to pay an electrician to install it, which suits an Owner with its own maintenance staff; a parts and labor warranty sends the manufacturer's service to the site and is bought where the Owner has no staff for the work or where a unit out of service costs the Owner revenue. (17.4)
17.5 Where a warranty period is not selected in the datasheet, the manufacturer's standard warranty shall apply, and its term shall be stated in the product data.
17.6 The Contractor shall warrant the installation, including every termination, the anchorage, the raceway entries, and the results of the field tests, for the project warranty period, and shall correct a unit that fails, loosens, or does not perform its test during that period at no cost to the Owner.
17.7 A unit or an assembly replaced under warranty shall be warranted for the remainder of the original period or for one year from the date of replacement, whichever ends later.

18 Spare Parts

18.1 The Contractor shall deliver spare parts of each type furnished, in the quantity indicated in the datasheet as a percentage of the installed count of ports of each unit type, rounded up to a whole unit, and shall obtain a signed receipt for them.
Spare Parts Furnishedrange

Spare Part Typescheckbox
☐ Connector and cable assemblies, each connector type
☐ Connector holsters and cable hooks
☐ Authorization cards or fobs
☐ Display and card reader modules
☐ DC power modules
NOTE A spare quantity is sized to the installed count and to the Owner's maintenance program, so no quantity is the norm and the field carries no default; the connector and cable assembly is the spare that matters, because it is the part a driver drops, drives over, or damages, and a unit without one is out of service until the manufacturer ships it. A zero records that the Owner replaces from the catalog. (18.3)
18.4 Spare parts shall be identical to and interchangeable with the installed parts, shall be delivered in their original packaging, and shall be labeled with the unit type and the connector type they serve.
