Description of the operating system
An arc-fault detection device (AFDD) or arc-fault circuit interrupter (AFCI) is a circuit breaker that breaks the circuit when it detects the electric arcs that are a signature of loose connections in home wiring.
Loose connections, which can develop over time, can sometimes become hot enough to ignite house fires dangerous arc (that can occur, for example, in a lamp cord which has a broken conductor).
An AFDD selectively distinguishes between a harmless arc (incidental to normal operation of switches, plugs, and brushed motors), and a potentially dangerous arc (that can occur, for example, in a lamp cord which has a broken conductor).
