WebApr 11, 2024 · An AFCI is a safety device that monitors the current flow through it. It detects abnormal situations such as arcing or short circuits, and once this happens, it trips its internal contacts – stopping all power from flowing so that there is no chance of any fires occurring. To detect an arc, look for spikes at a certain frequency and too many ...
WebMar 1, 2009 · The NEC doesn't require you to provide short circuit or ground-fault protection for service conductors, but the feeder overcurrent device provides overload protection for the service conductors.
