-Most motor circuits are protected by ____.

Quizplus · Accepted Answer

Most motor circuits require protection that is both time delay and dual element to provide both overload as well as short circuit protection. Dual element fuses can provide both, but inverse time circuit breakers may also provide similar protection. Instantaneous trip circuit breakers alone do not provide adequate overload protection, and non-time delay fuses do not provide adequate short circuit protection.
