Arc Fault Circuit Interrupter

An Arc Fault Circuit Interrupter (AFCI) is a circuit breaker designed to prevent fires by detecting a non-working (i.e., non-intended/non-useful) electrical arc and disconnecting the power before the arc starts a fire. A critical component to fire safety, these devices can save lives.

An important safety feature, an AFCI circuit breaker can be identified by the special colored button near its handles.

How AFCI Circuit Breakers Work

An AFCI should, but may not always, distinguish between a working arc such as may occur in the brushes of a vacuum cleaner, upon the operation of a light switch, the insertion or removal of a plug into an electrical receptacle, or during the operation of other household devices and a non-working arc such as those caused by a lamp cord that has a broken conductor in the cord from overuse.

Possible Causes of AFCI Circuit Breaker Trip

• Overload: When electrical usage overheats a circuit's wires.
• Short Circuit: Extremely high current that results from a fault on the circuit.
• Overheated Breaker: When the breaker itself has poor contacts or connections.
• Ground-Fault: Leakage of the intended circuit. This would include shock hazards, neutral to ground faults, and the differing current on the neutral wire when it is shared by another circuit.
• Arc-Fault: Sparks that occur on the circuit or lights and appliances.

Why AFCIs Are Important

Arc faults in a home is one of the leading causes for household fires. Each year in the United States, over 40,000 fires are attributed to home electrical wiring. These fires result in over 350 deaths and over 1,400 injuries each year.

National Electrical Code (NEC)

The National Electrical Code (NEC) is the standard for the safe installation of electrical wiring and equipment in the United States. The NEC, while having no legally binding regulation as written, is generally adopted by states and municipalities as the standards by which they enforce safe electrical practices within their jurisdiction. Considered the benchmark for safe electrical installations, the NEC is published by the National Fire Protection Association (NFPA) every three years.
