Combination AFCI and GFCI Circuit Breaker

Electrical Question: Is a AFCI and GFCI circuit breaker madeĀ  in the same circuit breaker?

  • After reading about the arc fault breakers and knowing about the ground fault breakers for some time.
  • I was wondering if the NEC, National Electrical Code, would be pushing manufacturers to create both AFCI and GFCI circuit protection in the same breaker?
  • Do you see this happening in the near future ?


This home electrical question came from: Jeffrey, a Homeowner from Flower Mound, Texas.
Additional Comments: Very worthwhile compilation of experience and know how.

Thanks for your electrical wiring question Jeffrey.

AFCI and GFCI Circuit Breakers

Actually your right on target. A combo AFCI and GFCI circuit breaker was already developed a few years ago but due to problems the item was taken off the market, I’m sure a replacement will be available soon.

    I see many different letters before and after the AFCI/GFCI combination breakers. Which one do I need for a home residence. I want to use it for the dishwasher. Thank you.

    • Dave Rongey says:

      Hi Victor,
      A GFCI breaker with the circuit wiring amperage rating will be fine for the dishwasher. It is important to match the circuit breaker amperage rating with the wire gauge amperage rating. For example a #14 AWG copper wire with THWN insulation is rated at 15 amps, and a #12 AWG copper wire with THWN insulation is rated at 20 amps.
      I hope this helps,


    When installing AFCI breakers, do you have to use MC Cable or conduit to the first box, or just pull Romex as normal and land it on the AFCI breaker?

    • Dave Rongey says:

      Hi Bill,
      The method of wiring for the AFCI circuit will depend on what is allowed in your location and what type of construction methods are used for the home. The objective is to protect the circuit wiring, and that is based upon how the wiring will be installed and what the local codes require. If the home has stud frame construction and type NM cable is allowed in that area then that will be the acceptable method. However if there is MC cable installed then MC cable will be required. Your local building department will be able to tell you the acceptable method for wiring the AFCI circuit.
