What is Arc and where I need to use Arc Fault breakers?
Electricity can be discharged unintentionally as a result of an ARC and not only its wasteful, it might also cause fire. Arc can be caused by damaged or worn insulation, an object pressing the electrical cord, screws and nails driven into the wire or staple is hammered in too deep on the wire. Currently Arc Fault breakers must be used for bedroom receptacles in new construction and in old construction only if new wire is run to feed the bedroom outlets. Gradually the code will change to require all wiring to be protected by Arc Fault breakers.
