John's advise is sound (as always). The FP suffers at "high loads" because it requires active cooling. Look at those vents at the rear and you will see fan impellers integrated into the motor assembly. This is why the body is so small in size compared to the power of the motor.

An FP at stall will almost immediately destroy itself regardless of the circuit breaker used (it might survive with a 20A, but I doubt it).

Bottom line, never stall a Fisher Price motor...
