A fused disconnect to an ATS then to a splitter with the 2- 200 Amp panels feeding off of it?
But 30KW is shy of feeding it all, is it not?

Wouldn't that depend on load?

How are the panels wired now? The transfer switch just goes in between the source and the panels.

So no breaker at the meter? Service rated transfer switch with disconnect. Sent from my iPhone using electriciantalk.com
Why?? Twice I've said what he needs. It's the easiest and most common setup for a (2) 200 amp panel service.

You've either got to have a main breaker to protect the ATS, or a SER switch which has a main. Can't feed unfused to non SER ATS.
May be part of the disagreement or clarification here.

Who makes that one joe. I called generac and they didnt seem to know. I get 3 or 4 calls a week for generators with 2 main panels. Every customer says they had electricians look at it and didnt know how to make it work.
Generac told me they get 5 to 6 calls a day about this and he didnt have an answer for me.

Excellent. .. about how much and is there any reason I cant use it with a generac or kohler
You'd have to check to see if is compatible. The control wiring will be different. GE uses a 2 wire control and generac uses a 3 wire.
