Full throttle?

The numbers are ambiguous and seemingly inconsistent:

10 amps total divided by 6 motors would be only 1.7 amps per CIM, which is less than their free amps.

50 amps per motor times 6 motors would be 300 amps, which would pop your main breaker.

Please elaborate.



Yes that was all per motor, but only 4 motors are on right now. It was also full throttle. However the 50 amps were only a spike as we reversed direction so the breaker didn't pop because it was instantaneous.

Also we thought about the 1/8" not being enough but it has worked previously, we are only experiencing this today. Also its pulling these amps on the blocks so the wheel drop shouldn't affect the amps right now...
