    Combination Arc Fault

    NEC 210.12 will require combination arc faults for bedrooms beginning January 1, 2008. Please explain what is a combination arc fault in contrast to a brranch circuit arc fault? Are these items now on the market and readily available? I have heard that the combination arc faults do not work properly if wired in series. Help! I'm a residential inspector!:-?

    Here is a link to NEMA and a FAQ page dealing with AFCI's.

    I personally haven't seen any combination AFCI breakers avaliable at my local supply house, but there are some manufacturers that state they have them avaliable.

      Can you explain what you mean by that?

        Does your AHJ actually adopt the new NEC on Jan 1? Here in Oregon it is usually April or May of code change year.

          This week, I was at a Trade Show, where Square D had literature on Combination AFCI:
          http://www.squared.com/us/products/circuit_breakers.nsf/unid/617D2D6F3F84CFB6852571F1005D526F/$file/comboafciFrameset.htm
          It's a combination of an ACFI and GFCI covering the full range of Arc Faults.
          While some states (2) have delcaired they will adopted the 2008 NEC, they have made an exception regardling AFCI's
          Just my $.02
          I found my easter eggs & my car keys, life is good!

            Jack the rule is actually in the 2005 NEC, as long as an area is using the un-amended 2005 NEC the requirement for combination AFCIs takes effect.

            Check out 2005 - 210.12

              I think you may want to go to that link again and read it closely. A combination AFCI is not a AFCI and GFCI combined. A Combination AFCI detects both parallel and series arching...This has nothing to do with GFCI protection.

                Cutler Hammer combination arc faults have been able to be ordered from my CH supplier for a few weeks now. They actually had the press release on their availability a couple months ago.

                  How are the new AF's going to be visauly identified from the old? What color will the test button be? I could not get this info from the link provided above.

                  I know you believe that you understand what you think I said but I'm sure you realize that what you heard is not what I meant.

                    Arc Faults Combination

                    The NEC 2005 and the IRC 2006 both require the use of the combination arc faults in bedrooms beginning January 1, 2008. Any building/electrical permit issued after January 1, 2008 is within the current IRC and NEC Code cycle and is already in effect (in Pennsylvania). Therefore, waiting for the next Code cycle to apply this existing code requirement is not applicable. The current code cycle contains this requirement even though it is not enforceable until January 1, 2008. As the AHJ, I must enforce this item as of January 1, 2008. Is the industry and the trades ready for this?

                      In your position as a representative of the AHJ, I believe you must.

                      Ready or not, here it comes.

                        At the Western Section IAEI meeting, Eaton, Square D and Siemens had combination AFCI devices on display and all three say they are currently available. At this time those are the only breaker manufacturers that have a listing for combination AFCIs on the UL website.
