Question

Quizplus · Accepted Answer

The National Electrical Code (NEC) allows electrical personnel to increase the ratings of thermal protection devices in cases where the original selection does not allow the motor to operate. For example, a motor may require a 125% or 115% overload protection device, but if the available devices are not rated high enough, the Code permits the selection of a higher rating to ensure safe and effective operation. This is detailed in NEC Article 430.32.
