A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit.Its basic function is to detect a fault condition and, by interrupting continuity, to immediately discontinue electrical flow. Unlike a fuse, which operates once and then has to be replaced, a circuit breaker can be reset (either manually or ...

Motor circuits only; the running current should be no greater than 80% of wire ampacity. Breaker may be sized anywhere from 125% to 250% of the wire and motor nameplate full-load current. Example: 12 gauge wire with 20 Amp breaker, measured load 18 Amp. This circuit is overloaded, load should be 80% of 20A or 16A max. Wiring method:
