I posted this in the NEC section and got no replies. I noticed this was the better place to post this question:
>>>>I am going to hang a 200-amp meter/main combo on the outside corner of my garage at the front of the house. On the back wall of my garage there is a 12/24 125-amp subpanel with lugs. Additionally, I cut in another 12/24 125-amp subpanel in my 3rd bedroom behind the door.
QUESTION: What size feeder should I use to the subs? I either want to go 90-amp, 100-amp, or all the way to 125-amp depending on what is the most cost effective. Should I go aluminum or copper? If so, what size wire do I need. I'll go with x/3 w/ground Romex. Panel #1 is about a 35' run and panel #2 is about a 70' run. THANKS!

Sorry for the double post! I'm a newbie here!
