: A big concern now is with a torquey drive system, you can over load the 60 A circuit breaker pretty easily. We're planning on 20 or 25 A auto resetting CBs on each drill motor, so we don't hit the big one and get stuck out there during the match.


Hello All;

You need not "cripple" your drivetrain because of concern over the 60 amp breaker.

I've previously posted my test results on the board (someplace well below). The key is you can draw 100 amps for almost 2 minutes before it trips; it will hold 200 amps for about 8 seconds. So with 30 amp breakers on the motors, so long they aren't tripping, you are pretty safe.
