Actually,
for periods under 5 seconds the main breaker will not trip with currents up to 600 amps. As the temperature inside the breaker rises, this over current trip point is reduced. Think about this, four chalupa motors in stall is 129 amps x 4=516 amps and still no main breaker trip. However, the 40 amp breakers would likely be tripping. Since they are auto reset, the effect is erratic motor operation and a loud clicking from the robot.
