What is an AFCI?

The National Electrical Code, Section 210-12, requires that all branch circuits supplying 125V, single phase, 15 and 20 ampere outlets installed in dwelling unit bedrooms be protected by an arc-fault Circuit interrupter. Eventually they will be in more areas but the NEC selected to require them on bedroom circuits first because a CPSC study showed many home fire deaths were related to bedroom circuits.

The AFCI (Arc Fault Circuit Interrupter) breaker, will shut off a circuit in a fraction of a second if arcing develops. The current inside of an arc is not always high enough to trip a regular breaker. You must have noticed a cut or worn piece of a cord or a loose connection in a junction box or receptacle arcing and burnt without tripping the regular breaker. As you can guess this is a major cause of fires in a dwelling.

There is a difference between AFCIs and GFCIs. AFCIs are intended to reduce the likelihood of fire caused by electrical arcing faults; whereas, GFCIs are personnel protection intended to reduce the likelihood of electric shock hazard. Don't misunderstand, GFCIs are still needed and save a lot of lives.

Combination devices that include both AFCI and GFCI protection in one unit will become available soon. AFCIs can be installed in any 15 or 20 ampere branch circuit in homes today and are currently available as circuit breakers with built-in AFCI features. In the near future, other types of devices with AFCI protection will be available.

If a GFCI receptacle is installed on the load side of an AFCI it is possible for both the AFCI and the GFCI to trip on a fault if the current exceeds the limit for both devices. It is also possible for the AFCI to trip and the GFCI to not trip since the two devices could race each other. However, in no case is safety compromised.

How should outlets be installed in a kitchen area?

All 15 and 20 ampere receptacles installed within 6 feet of a kitchen sink or wetbar shall have GFCI protection. Receptacles in a kitchen used to serve counter tops should be supplied with at least two 20 amp branch circuits, for small appliances. Each fixed appliance (refrigerator, stove, dish washer) shall have its own dedicated circuit. On counter tops 12 inches or wider a receptacle shall be installed so that there is no more than 24 inches between outlets. Receptacles outlets installed to serve island counter tops shall be installed above, or within 12 inches below the counter top. There shall be no more than 24 inches from center line of counter top. No receptacle shall be installed face up on a sink counter top.
