A designing a system that consist of an outdoor diesel genset that is going to serve an Article 700ATS, an Article 701 (for smoke exhaust) ATS and and Article 702 Optional Standby ATS.
The Smoke Exhaust ATS per 909 of the IBC needs to be in a rated room and isolated from the service switchgear. The Article 700 ATS needs also to be in a rated room. I believe the 702 ATS can go in either the room with the other two ATS's or in the normal switchgear room. I'm planning on putting all of the ATS's in the same 1 hour rated room.
Coming from the generator, I'll go to a wireway with three breakers tapped off feeding each of the three ATS's. Does this wireway and associated breakers need to be in the same room with the ATS's. Where is this indicated in NFPA 110?
