I am planning to wire a new house.
I am going to have a 200Amp combo/main with 40 branch circuit breakers outside and one 200Amp subpanel inside. I will have all of 120 volt circuits in the indoor subpanel and all the 240 volt circuit on the outside panel. The only reason i have two sets of 40 circuit panels is for future expantion.

Do you think i should have one main outside and all the branch breakers inside? or should i have everything outside?

house is about 3000 sqft.

Thank you
Edward
