Check permanent electrical circuit wiring, arcing, poor insulation, shorted wires An afci is a special circuit breaker that is designed to help protect against fires resulting from electrical arcing, often caused by damaged or deteriorated wires and cords. A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit.

The branch circuit overcurrent protection is provided by a fuse or circuit breaker usually located in a centralized panelboard that is served with power by the local utility.

That is because they are not designed to detect sudden dangerous arcs. Reset circuit breaker by pushing its handle to the off position and then to the on position: Check permanent electrical circuit wiring, arcing, poor insulation, shorted wires Gfci and afci circuit breakers:
