The Branch/Feeder AFCI can only detect line-to-neutral and line-to-ground arcing faults. Combination AFCIs provide protection against the high-energy parallel (line-to-neutral and line-to-ground) arcing and low-energy series arcing. “Combination” does NOT mean an AFCI + GFCI.

What is the difference between an arc-fault breaker and a combination arc-fault breaker?

Combination arc-fault circuit breakers are not the same as dual function circuit breakers. While they may “sound” the same, the combination arc-fault circuit breaker does not provide the same protection as a dual function arc-fault/GFCI circuit breaker does.

What is a combination type AFCI?





A Combination Type AFCI detects all three types of arcing: line-to-neutral, line-to-ground, and series arcing.” The most probable and convenient “means” to meet the AFCI Protection requirement for new construction dwelling units is through use of a Combination Type AFCI Breaker, 210.12(A)(1).

Where are combination arc-fault breakers required?

2008 Edition: Combination AFCI protection is required in all single-phase, 15-amp, and 20-amp non-ground fault circuits supplying power to living areas including living rooms, rec rooms, family rooms, dining rooms, libraries, bedrooms, sun rooms, hallways, closets, and similar areas.

What is a combo circuit breaker?

The system combination-type AFCI (or dual function AF/GF) is designed to detect and interrupt the following conditions: OVERCURRENT AND SHORT-CIRCUIT CONDITIONS. The system combination-type circuit breaker will detect and interrupt over-current and short circuit conditions per UL 489.

Can you put a GFCI outlet on a AFCI breaker?

It’s perfectly fine to connect a circuit that is GFCI on an arc fault breaker, so don’t worry about damaging the breaker if you decide to do this.

Can I use AFCI outlets instead of AFCI breakers?





AFCI outlets work with any type of wiring and are not dependent on the type of breaker in the panel. They are also easily accessible and have a level of familiarity with users with the TEST and RESET buttons that are also present on GFCI outlets.

Does a refrigerator need AFCI?

Refrigerator Circuit
This circuit usually does not require GFCI protection unless the outlet is within 6 feet of a sink or located in a garage or basement, but it generally does require AFCI protection.

Does an AFCI breaker protect the whole circuit?

An AFCI device protects the entire circuit from the electrical panel through the downstream wire to the outlet, along with all appliances and equipment plugged into that circuit. If an AFCI device trips, it is most likely the result of a potentially dangerous arcing condition detected by the device.

Why do some arc fault breakers have a pigtail?

Historically, AFCI and GFCI breakers needed a pigtail wire to get neutral. Some installers found that messy. So some newest panels do a positioning trick with the neutral bus so the breaker can clip onto it also. This is called “Plug-on neutral”.

Why does my AFCI breaker keep tripping?



Your AFCI breaker trips due to hazardous sparking, helping to protect you from electrical fires. Common reasons for your AFCI breaker trips include incompatibility, faulty devices, damaged or faulty wiring, and overloaded circuits. Identify the problem by isolating the device or circuit that’s having issues.

Does a washing machine need to be arc fault protected?

Nearly every room/ area in a dwelling unit requires AFCI protection, so no matter where you put a clothes washer, it will be AFCI protected in a newer home.

Do I need GFCI outlets if I have a AFCI breaker?

In 2014, the National Electrical Code® (NEC®) introduced AFCI requirements for kitchens and laundry rooms. The code had previously required that these locations needed only GFCI protection, but for added safety they are now required to have both AFCI and GFCI protection.

Where are AFCI breakers required 2020?



AFCI current requirements in the NEC 2020 code:
Common rooms. Hallways and closets. Kitchens. Laundry areas.

Where are arc fault breakers required 2021?

16 states that AFCI protection is required for all 120-Volt, single phase, 15 and 20 amp branch circuits supplying outlets or devices installed in living rooms, parlors, libraries, dens, bedrooms, sunrooms, recreation rooms, closets, hallways, laundry areas, and similar rooms or areas.

Do light circuits require AFCI?

AFCI requirements.
The NEC requires that virtually all branch circuits for lighting and receptacles in a home must have arc-fault circuit-interrupter (AFCI) protection. This is a form of protection that guards against sparking (arcing) and thereby reduces the chance of fire.

Does dishwasher require AFCI?

The National Electrical Code (NEC) does require garbage disposals and dishwashers to have arc fault circuit interrupter (AFCI) protection.

Can bathroom lights and outlets be on same circuit?



The Bathroom Needs at Least Two Dedicated Circuits
This is no more. The bathroom electrical code now stipulates that the bathroom must have dedicated circuits that aren’t shared with outlets or lights in any other room. You must provide at least two of these circuits.
