Arc fault circuit breaker wiring diagram.

Afcis are designed to sense an arc which is an electrical leak caused when a hot wire touches a neutral or ground but doesn t trigger the circuit breaker. It reveals the elements of the circuit as streamlined forms and the power and signal links between the devices. Requirements for gfci ground fault circuit interrupter protection have been in place for many years but more recently the national electrical code nec began requiring another form of protection known as arc fault circuit interrupters afci. In this case the afci will detect the arc fault and cut off the main power supply to the connected devices and equipment hence prevent the chances of electric fire.

A wiring diagram is a streamlined standard pictorial depiction of an electrical circuit. Arc fault breaker wiring diagram what is a wiring diagram. An arc fault circuit interrupter or afci breaker prevents fires by sensing when an electrical arc is about to occur and instantly disconnecting the damaged circuit before the arc builds enough heat to catch fire standard circuit breakers don t always trip in these instances because standard breakers are designed to respond to a sustained amount of heat not a quick surge. To avoid false tripping operation do not install and wire an afci gfci gfpe ground fault protection of equipment or combo of both afci gfci circuit breakers on shared neutral wire with other circuits.

An arc fault circuit interrupter afci also known as an arc fault detection device afdd is a circuit breaker that breaks the circuit when it detects an electric arc in the circuit it protects to prevent electrical fires. Obc afci outlet branch circuit arc fault circuit interrupter can be used on all types of electrical wiring installation for both series and parallel arc quenching. In 2002 this protection became necessary for bedrooms and in 2014 section 201 12 of the code required all new construction to provide afci. A wiring diagram is a straightforward visual representation in the physical connections and physical layout associated with an electrical system or circuit.

Arcing faults occurs unintentionally in a circuit when the motor switch opens or a line hot wire cuts and touches the neutral.
