Info in previous responses is all potentially relevant, but ...

Suggest you take the time to learn about basic home circuit
design and amperage loads. Then inventory elec. devices you
presently use (and their max amp draws) and predict any that
you might want to add in the coming years. Object is to
estimate max house amperage (100, 125, 150, 200) -and-
number of circuits needed in new service box.

I don't have a handy reference to home circuitry, but it's not
rocket science by a long shot. Maybe someone else can suggest
a suitable info source.

wiring simplified by hp ricter and associates is a great reference
