If the motor is on a 40 amp breaker, it would take 40+ amps for slightly over a second to trip it. The breakers are slow-blow.

Driving in full power with can get close to the 40 amps required to trip the breaker, depending on your gear ratios and stuff. Pushing gets even scarier. If the drive train wasn't built for high torque and it's used in a pushing match, it's possible for it to easily draw 50+ amps. That, over a few seconds, could trip the breaker.

Good thing is these breakers are auto reset, so they'll reset after 2-10ish seconds.
