What is considered emergency power? What is classified as legally required? Still yet what would go on a COPs system? Does a fire pump need backup power and if so does it need its own ATS?


Does a cops area require normal power as well to any degree?

Go to Chapter 27 of the adopted Building Code (guessing your jurisdiction is based on the ICC model codes) and they call 700 (Emergency) and 701 (Standby). Nothing special for COPS

Link or how to get the ICC? :ashamed1:
 
According to NEC 700, an emergency load is whatever a code or other governmental authority says is an emergency load. For example, building codes will call for egress lights to be treated as emergency loads. But you can satisfy that requirement with local batteries or with a central inverter - no absolute need for a generator.

According to NEC 701, a legally required standby load is whatever a code or other governmental authority says is a legally required standby load. For example, some cities require at least one elevator bank in a high rise building to be treated as a legally required standby load. Also, sometimes a smoke evacuation system is required to be treated as a legally required standby load.

If a fire pump needs a backup power supply, the transfer switch is built into the fire pump controller.

Any typical list of examples?

And again I want to ask- why the need for two or more ATS?
