Re: Breaker for Globe Motor?

I always thought that the thermo-trip design of the breaker (auto-reset) allowed a little leeway, so that you can run the motor at currents higher than rated (stall current), and in this way, a stall underrated breaker, for starting motors, would still be adequate.

I also had thought that the breaker was to prevent motor damage mostly, in addition to kill a short to the frame. So wouldn't you actually want an underrated breaker? To protect your motor to an extent?

But more than anything, the rules are a great place to start. I should probably go back over them now that I think about it...
