You are calculating your demand incorrectly. You're max draw is 70 amp @ 120
volt. The feeder you intend to run is 100 amp @ 240 volt. That's 200 amps @
120 Volt. What gfretwell suggested #6 copper, is 60 amp @ 240 volt or 120
amp @ 120 volt. More than enough for your load


From what you say there 40a with #8/3 would be more than enough. You
will balance 80a across the 2 hot legs but going 60a is just a few
bucks more for 6/3. The breakers and panel will probably be the same.

So does that mean I would only need a 60A double-pole breaker in the
main to feed the subpanel? This breaker will feed two hots (240v) to
the subpanel bus bars, and then I can pull up to 96A (80% of 120) of
120v from that subpanel?
