QOD for 1/26/07 - AFCI's

[Jae Williams]

Because of complaints from builders and electricians who didn't fully understand the AFCI the Great Grand Exhalted Governor of the State of Ohio recently rescinded the 2008 NEC and reverted to the 2005 NEC as the code of choice for the great State of Chaos...I mean Ohio.

The builders didn't like the cost, either...

Joint Committee on Agency Rule Review (JCARR) (attachment) has scheduled a hearing for June 2, 2008 1:30 P.M. William McKinley Room (Statehouse Room 121)77 South High Street (Concourse Level) Columbus, Ohio 43215 (614) 466-4086 www.jcarr.state.oh.us to review the OBBS proposed rule change affecting the 2008 National Electrical Code.

The Director of JCARR, Mr. Bill Hills encouraged interested parties to testify at this hearing, however he cautioned that testimony for the JCARR hearing is limited to the criteria that may invalidate a proposed rule. JCARR does not have the authority to vote for or against a particular rule, rather they can only invalidate a rule if it does not meet one of the required criteria. NEMA sent a letter to JCARR on April 10, 2008 requesting a review the Rule Summary and Fiscal Analysis. See (4) of the criteria required to be met.

Is there more info than this? The above came from NEMA.

I thought it was only the interior rooms and not the kitchen, bathrooms nor laundry room. Those were to be GFCI protected. Right? Wrong?

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.

The definition of arc-fault circuit interrupter given in 210.12(A) explains its function. The basic objective is to de-energize the branch circuit when an arc fault is detected.

Arc-fault circuit interrupters are evaluated in UL 1699, Standard for Arc-Fault Circuit-Interrupters, using testing methods that create or simulate arcing conditions to determine a product's ability to detect and interrupt arcing faults. These devices are also tested to verify that arc detection is not unduly inhibited by the presence of loads and circuit characteristics that may mask the hazardous arcing condition. In addition, these devices are evaluated to determine resistance to unwanted tripping due to the presence of arcing that occurs in control and utilization equipment under normal operating conditions or to a loading condition that closely mimics an arcing fault, such as a solid-state electronic ballast or a dimmed load.
UL 1699 is the standard covering arc-fault devices that have a maximum rating of 20 amperes and intended for use in 120-volt ac, 60-Hz circuits.

These devices may also have the capability to perform other functions such as overcurrent protection, ground-fault circuit interruption, and surge suppression. UL 1699 currently recognizes five types of arc-fault circuit interrupters: branch/feeder AFCI, combination AFCI, cord AFCI, outlet AFCI, and portable AFCI.

Placement of the device in the circuit and a review of the UL guide information must be considered when complying with 210.12. The NEC is clear that the objective is to provide protection of the entire branch circuit. (See Article 100 for the definition of branch circuit.) For instance, a cord AFCI cannot be used to comply with the requirement of 210.12 to protect the entire branch circuit.

The type of AFCI required to comply with 210.12(B) was the subject of a revision in the 2005 Code. To expand the level of AFCI protection for cord sets that are plugged into receptacles supplied by AFCI-protected branch circuits, the use of combination-type AFCI devices is required. These devices provide the combined protection required by UL 1699 for branch/feeder and outlet type AFCIs. The product standard requires specific marking on AFCI devices to indicate the type of protection provided. Combination-type AFCIs bear such a marking. Exhibit 210.21 is an example of a circuit breaker that provides combination-type AFCI protection. In addition to the revised type of AFCI protection required, the location of the AFCI device in the circuit now provides a new option. The exception permits the AFCI device to be located at the first outlet supplied by a branch circuit, provided that the wiring method from the circuit overcurrent protective device to the outlet is rigid metal conduit, intermediate metal conduit, electrical metallic tubing, or steel armored cable. These wiring methods afford a higher level of physical protection for branch-circuit conductors. There is no length restriction on the branch-circuit conductors from the OCPD to the first outlet as long as the conductors are contained within one of the wiring methods identified in Exception No. 1.

Mike......It appears that Frank "Barney Phyfe" Carrio and his plastic moderator badge has taken a stand against Joe Farsetta, Chairman of the ESOP Committee.

I wonder who will win this one.

[James H. Bushart]

All members should be warned that the poster, Joe Tedesco, has been expelled from InterNACHI twice and has caused harm to members by utilizing telephone calls and emails to interfere with their personal lives...involving their families, employers, and others.

Frank Carrio is a moderator who has chosen to ignore the ban placed on Mr. Tedesco by the ESOP Committee Chairman, Joe Farsetta. This ban was put into effect to protect the membership.

Please be advised that nothing can be done by InterNACHI or its moderators should Mr. Tedesco decide to harass you as he has done others. It is best to simply read...but not to engage him in any posts.
