Jim Katen Posted January 25, 2008 Report Share Posted January 25, 2008 From the Seimens press release: Combination Type AFCIs, which will be required by 2005-2008 NEC starting Jan. 1, 2008, protect against both of these arc faults plus series arcs, which can be caused by broken conductors, loose screws and a host of other invisible faults. Let the nuisance trips begin . . . - Jim Katen, Oregon Quote Link to comment Share on other sites More sharing options...
Joe Tedesco Posted January 29, 2008 Report Share Posted January 29, 2008 210.12 Arc-Fault Circuit-Interrupter Protection. (A) Definition: Arc-Fault Circuit Interrupter (AFCI). A device intended to provide protection from the effects of arc faults by recognizing characteristics unique to arcing and by functioning to de-energize the circuit when an arc fault is detected. (B) Dwelling Units. All 120-volt, single phase, 15- and 20-ampere branch circuits supplying outlets installed in dwelling unit family rooms, dining rooms, living rooms, parlors, libraries, dens, bedrooms, sunrooms, recreation rooms, closets, hallways, or similar rooms or areas shall be protected by a listed arc-fault circuit interrupter, combination-type, installed to provide protection of the branch circuit. FPN No. 1: For information on types of arc-fault circuit interrupters, see UL 1699-1999, Standard for Arc-Fault Circuit Interrupters. FPN No. 2: See 11.6.3(5) of NFPA 72®-2007, National Fire Alarm Code®, for information related to secondary power supply requirements for smoke alarms installed in dwelling units. FPN No. 3: See 760.41(B) and 760.121(B) for power supply requirements for fire alarm systems. Exception No. 1: Where RMC, IMC, EMT or steel armored cable, Type AC, meeting the requirements of 250.118 using metal outlet and junction boxes is installed for the portion of the branch circuit between the branch-circuit overcurrent device and the first outlet, it shall be permitted to install a combination AFCI at the first outlet to provide protection for the remaining portion of the branch circuit. Exception No. 2: Where a branch circuit to a fire alarm system installed in accordance with 760.41(B) and 760.121(B) is installed in RMC, IMC, EMT, or steel armored cable, Type AC, meeting the requirements of 250.118, with metal outlet and junction boxes, AFCI protection shall be permitted to be omitted.
