I'm having a discussion on another forum, but I don't quite agree with what they're saying. I don't know their qualifications, and I don't want to start an argument over this, so I figured I'd post here where I know there's knowledgeable folks.
I have 100a service to my house. If I load 55amps on one leg, and 50 on the other, will the main breaker trip? Or, does it need to see 100 amps on each leg (or at least over 100 on one or the other).
Basically, the other forum is saying that I could draw 200 amps at 120v, because the main breaker is rated PER LEG. So, as long as my 120v circuits are evenly distributed across the two legs in the panel, I could draw up to 200 amps.
I'm saying that if I draw over 100 amps, period, I'm going to pop the main.
