Per above code, level 1 EPSS (emergency power supply sytem) equipment can not be located in same room with the normal service equipment if service equipment >150V to ground and >= 1000A. Can someone give me example of level 1 EPSS equipment? I assume this includes main emergency generator distribution panel, emergency ATS (serving egress lights, fire alarm, life-safety equipment, etc.), will the first panel downstream of emergency ATS counts as well or just the emergency ATS?

Since an EPSS Level 1 requires a 10 second power supply availability, so that would be a NEC 700 load which is identified in the adopted building code Chapter 27 with loads labeled as "Emergency"
