Question

Quizplus · Accepted Answer

The service factor of an electric motor is determined by its reserve capacity, which is the amount of overload the motor can handle for short periods of time without sustaining damage. The National Electrical Code and National Electrical Manufacturers Association code provide standards for electrical equipment, but they do not directly determine the service factor of a motor. The required wire size supplying power to the motor is important for ensuring safe operation of the motor, but it does not determine the service factor.
