If your robot is going to constantly draw more than 60 amps, say 100-120 amps, couldn't you put a heat sink or a fan blowing in the circuit breaker? Would that be legal?

And also, could you put a breaker board with 3 x 20 amp auto-resetting breakers in serial between the 60 amp and your main control board. So the power would flow from the 60 amp breaker to the board with 3 x 20 amp breakers, which are connected to each other in parallel, and then connected in serial to the 'main' circuit breaker board. (It would not be legal with 30 amp breakers because they are only for speed controllers) I'm pretty sure that is possible and it 'should' trip before the 60 amp breaker trips, telling you that the robot is drawing too much power.

BTW: This would only work if the 3, 20 amp breakers have the same resistance. And I would not try it unless I ask FIRST, first.
