400 amp service

[Kessler4130]

It would be nice if you could purchase the ATS now. Mount downstream of meter. Then install a trough in which you could split off and mount two 200 disconnects to act as feeder for your panelboards.

This would allow simply coming in whenever the genset is purchased and wiring into the ATS and setting up controls.

That would be wonderful, but unfortunately it seems everything has to be as difficult as possible lol. So to make it easy on me I may just opt for the 400 amp main panel with a 200 amp sub feed and call it a day. Unless they make a 400 main breaker panel with feed through lugs or something of the like that is listed for the purpose.

Jesse, square D has several NQOD panelboards that would do what you want...either a 400A MCB panel with up to 225A subfeed breaker, or a 400A MCB panel with feed-through lugs (for a 400A feeder to your 2nd panel).

If you have their digest look on pages 8-5 to 8-12. I don't think they are stock, but you can order the tubs to get started, adn recieve the guts later. You can use bolt-on or plug on breakers with NQOD's (QO breakers).
