Can anyone give me advise on the best way to do a back up generator. This is a big house. We're thinking 225 amp service; 100 amp sub (for the generator circuits); 4/0 Copper SEU...

We've put in quite a bit of Cutler-Hammer stuff for this. Basically it just disconnects the main and backfeeds a breaker. I'll try to get back with a panel name.
