Well you guys have helped me on the last generator questions so much. I could use your help on my other generator issues.
Heres the new story....
We have a residential home, with 2, 200A service sub panels. We will be installing a 35+Kw Genny, w/ an ATS.
The way I figured the install is... Out of the meter to the ATS, from the ATS to a Disconnect,.. At this point we need to split and go out to the 200a panels.
Sounds good to me... but..
The disconnect, where I can come in with that 400a and split it to the 2 , 200a panels. What is the best route to go here, a 4 space panel? Install two 200a breakers then out to the panel? I checked with the supply house they don't seem to be familuar with a disconnect specific for this application.
So... feel free to comment. .. and thank you.

Wow thats gonna be a fair size ATS eh! If it were me for the "inside" part regardless if there is a generator upstream or not, I would come into a 400 A disconnect then out to a splitter trough and out of that with 2 x 200A fused disconnects or breakers. Whatever you prefer.. That way with the trough it allows you to "expand" a bit should the homeowner want to add something down the road such as a " shop" or something along those lines.
Just out of curiousity, I do not know what the codes are in your area but should there not be some sort of disconnect between the meter and ATS?

At least you are not trying to put this on a 10Kw or worse a 120v 2000w... 35 is at least in the neighborhood for the possible load.
I'm a little unsure of the meter and main(s)? I assume from what I can gather that you have a 320c/400 meter base - how does that get to the two 200a panels? 2 main panels? Or is it a meter/main combo w/ 2, 200's?
Either way I would say size your gennie disco for the generator and take that to a gutter and split that with taps to two 200a ATS's. I would also set it up so that one kicks over later than the other to stagger any in-rush. And.... You will want to have all of this on the load side of the mains or you are going to have possible issues with the POCO and a bonding nightmare. Your best situation would be a meter/main combo w/ 2, 200's then to two ATS's. IMPO
