Use the circuit. The breaker is there to protect the wiring, not the motor; you run light bulbs on 15 amp circuits and they don’t draw anything close to 15 amps. You could replace the 50amp breaker with a lower amperage breaker, that more closely matches the motor, if you like, the wiring will just be over sized. The bad situation is having too large a breaker for what the wiring can handle.
