SynC · Topic
These are the standards in the SynC Standards library 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 — ratings, materials, setpoints, and the standards each is verified against. All of it is free to read without an account and published under CC BY-SA 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.
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.
Dedicated indoor electrical rooms and closets housing service entrance equipment, distribution switchgear, switchboards, panelboards, motor control centers, dry-type transformers, automatic transfer switches, indoor standby generators or paralleling switchgear, DC battery systems, and the associated grounding, raceway, and control infrastructure for commercial, institutional, healthcare, higher-education, data center, and industrial buildings. Covers working clearances, dedicated electrical space, headroom, door and egress arrangement, fire-resistance ratings of enclosing assemblies, ventilation and cooling for equipment heat rejection, room illumination, convenience power, drainage and plumbing restrictions, security and access control, equipment anchorage, finishes, and signage.
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.
