I need some help with choosing the right gauge wire, I am adding a
subpanel that will be 85 feet away from the main(200a) in my garage
with a basic 125 panel and the most I would use now would be 75 amps(at
once) and all I can find are 60 or 100 amp breakers, so I want to go
with the 100 incase I ever need it in the future. So the question is
will 2ga x3 and one 4ga be enough? and also for determaning the gauge I
saw in a chart that ambiant temp also effect it and in my attic in az is
about 160f.
thanks
justin
