Generators
These are the standards in SynC Standards that cover Generators. Each one is a complete, plain-language specification: the scope it applies to, the requirements that govern it, and a structured equipment datasheet listing the values a project has to decide, with the standards each is verified against. All of it is written and maintained by SynC, free to read without an account, and published under CC BY 4.0.
A standard usually carries several topics, so most of the entries below also appear under neighbouring subjects. The topics each one carries are listed on its own page.
Standards
- Automatic Transfer Switches
Automatic transfer switches rated 1000 V and below, listed to UL 1008, that move a load between a normal source and an alternate source without operator action. Covers the switching mechanism, transition type, bypass-isolation construction, neutral treatment, the controller and its sensing, time delays, exerciser, load management and communications provisions, ratings including withstand and closing and short-time ratings, service-entrance construction, enclosures, identification, factory and field testing, installation, warranty, and spare parts, for switches serving emergency, legally required standby, optional standby, critical operations, and health care essential electrical system loads.
- Electrical Rooms
The dedicated indoor electrical room and the electrical closet as a space: the room that houses service equipment, switchgear, switchboards, panelboards, motor control centers, dry-type transformers, transfer switches, drives, UPS modules, control-power batteries and the open or paralleling generator sets installed indoors. Covers the working space and the dedicated electrical space the adopted electrical code requires about the equipment, headroom, the number of entrances, door swing, clear opening and panic hardware, locking and free egress, the fire-resistance rating of the enclosing construction where a code sets one, the exclusion of piping and ductwork foreign to the electrical installation, water protection at the door and on the floor, the heat-release basis and the ventilation or cooling performance the room has to deliver, the temperature and humidity limits taken from the equipment ratings, illumination and emergency illumination of the working space, the convenience receptacle, housekeeping pad provision, floor finish, the room ground bar, the signs on the room door, the coordination drawing that proves every clearance before the room is framed, and the field verification before the room is closed in and before equipment is set.
- Engine Generators
Packaged stationary engine-generator sets rated 1000 V and below, listed to UL 2200, furnished as the alternate source for emergency, legally required standby, optional standby, and critical operations loads, and sets the project applies as a prime or continuous source. Covers the engine and its fuel requirements by fuel type, the alternator and its excitation, the governor and voltage regulator, the set-mounted controller and the remote annunciator, the main line circuit breaker and the neutral bonding at the set, the cooling system, the fuel system on the skid including the sub-base tank, the exhaust silencer and aftertreatment, the enclosure and its sound attenuation, the starting batteries and charger, vibration isolation and seismic certification, factory and field testing, installation, warranty, and spare parts.
