    Is this a new home your are building for yourself or an existing home?

    If it is an existing home, what is the electrical service to it now?

    Just a suggestion, but please call a licensed electrician to do the load calculation for you.

    From the sound of it, unless you are an electrician I would NOT mess with this. This does not sound like a home a DIYer should be wiring.

    Off the cuff I would say 400A.
