Thanks, I will do the breaker box math as soon as I get home. Another detail I have run across and trying to sort out, do I want single phase (costs less) or three phase power (costs more)? I cant think of much except the electric oven that might be three phase, but I am guessing three phase is what I get from the utility provider into the breaker box. I see the mid-range house generators are mostly single phase. I guess that works but is not as good or efficient as three phase. At some point there has to be a knee in the curve for cost/benefit.
Three phase is mostly for industrial use.
Some of your loads like an oven, electric dryer or AC may have two ganged breakers (two that switch together on one throw). Those are your 2 phase loads.
They would not be operable with a single phase generator.
