Can you put 10-3 UF cable on a 50 amp circuit breaker?

A #10 copper conductor with an insulation rating of 90 degrees C is rated at 30 amps. The only time that a breaker larger that the load maximum capacity can used is in motor connections. A breaker can be used sized at 250% of the motor's full load amperage. In this case a 50 amp breaker can be used on a #10 conductor if the motor's full load amps falls within the amperage's of 20 - 22 amps.
