My boat dock/pier lights, etc. job passed inspection first time:) Got another project I'm bidding on. Old nursing home that has part of it that was never put on the standby generator system. They want to come off the existing ATS Life Safety Panel to feed an existing panel that is approx. 200 ft. away in another "wing" of the home. The panel that they want to feed, has only 4 single pole breakers that supply lights over beds, recpts. that are at the beds, and 1 30 amp. double pole breaker that I'm not sure what it feeds. Other than the correct wire size, pipe size, grounding, etc., can anyone think of anything else I might be missing? One problem I think I see might not be right, is that the circuits that are feeding the room lights, are sharing a conduit that feeds a room air conditioner out of another panel that won't be on the life safety panel after it is changed over. This is in each room. There are about 8 rooms that are involved. According to what I read that is definitely not acceptable. In order to accomplish what they want, the a/c's will have to be put on the same panel, or either the a/c's or room lights and recpts. will have to be run in separate conduits. Am I missing something? If I have to put the a/c's in the same panel, that will involve figuring the load of all combined a/c's and lights etc., bigger subpanel, which is now fed out of a traugh that is probably 30 years old, probably bigger feeder, and possibly bigger main panel. Looks like quiet an undertaking. Thanks if you can understand anything I said
Defining a 'Life Safety' panel, and the associated circuits and wiring methods is not as clear cut as you may think in an existing structure.
Connecting an existing panel to the gen, IMHO would be acceptable, as it is providing standby power to an unprotected area.
Now, are the existing receptacles that are on the gen, identified as such (red device or cover). You should consider ID on the circuits that are involved. Presenting some 'improvements' to the AHJ sure can't hurt.
