I'm nearly certain I know the answer to this question but not sure. I've got an existing Essential Electrical System with LS and Critical and a Equipment Branch ATS's. The existing EQ branch is 600A.
But I'm adding a 1000A EB ATS to this switchboard. At 1000A, my brain says Ground Fault. Now I realize that there will be no ground fault for Life Safety and Critical (i.e. for the Emergency Systems) regardless of size. But what about the EQ branch. I believe the answer that it too does not get ground fault.
True?
Thanks,
Mike
