A motor might require much more than 10 amps when starting or at some point in normal operation. Follow the manufacturer's instructions.

@Carmen43p,
well I can get you to the point of rating your breaker to the wire size, which 10 gauge wire is only rated up to a 30 amp breaker.
Continuous motor loads require you multiply by 125% 1.25
