The correct choice is based on the guidelines established by the National Electrical Code (NEC) and general practices regarding motor conductor sizing. For motors, the minimum size of circuit conductors is determined by factors such as the motor's full-load current rating, ambient temperature, and the type of insulation used in the conductor.

In typical scenarios for smaller motors, the minimum permitted size for circuit conductors is often 14 AWG for motors with a full-load current that does not exceed certain thresholds. This sizing ensures that the conductors can handle the current without overheating, thus promoting safety and reliability in the electrical system.

It’s important to note that for larger motors or different conditions, 10, 6, or 12 AWG may be required, particularly as the motor's full-load current increases. However, in this context, the specified minimum size conductor, reflecting common practices for specific circumstances, is identified as 14 AWG. This aligns with the NEC's safety guidelines, which aim to prevent overheating of conductors and ensure efficient operation of the motor.
