400 amp service

4359 Views 3 Replies 4 Participants Last post by  jett95
Hello,

I have a customer with a 400 amp service coming into a 2pole 400 amp disconnect (cat# TJD422400) to a GE 400amp residential main lug electrical panel(ALU1424MB).
He already bought a 20kw kohler generator with a 200amp automatic transfer switch.

(I am trying to get the picture of disconnect on my post)

My questions:

In order to make the auto transfer switch work on such a system, what I think I can do is:
Remove one set of the 200amp feeders coming from meter can to 400 amp disconnect switch, and re-feed it into the new automatic transfer switch.

From there, I will/would remove existing 400 amp electrical panel, or should I say remove what circuits I want to be on the generator and install into a separate 200 amp electrical panel.

Does that make sense? your thoughts?

I see an issue - the 400a disco is going to have to have 2 x 200a breakers, one to the non-generator panel, the other to a transfer switch, then onto the generator powered "gen" panel. But from what I've heard from people doing this, the customer is going to want EVERYTHING on the generator panel.
