Yes, all outlets in bedrooms, or served by the bedroom circuit must be Arc-fault protected. This also includes the wiring to the bedroom. See definition of outlet in Article 100 of the 2002 NEC. :)

Are you sure about the smoke detectors having to be on the AFCI? I usually wire the smokes on their own dedicated cicuits and link them all together.

Wayne, the requirement in the 2002 NEC is for all 15 or 20A, 120 V dwelling unit bedroom outlets to be AFCI protected. Look up the definition of outlet in art 100.
But some local agencies have exempted smoke detectors from being on an AFCI circuit.

Hurk, 230 volt equipment such as heaters, AC's is normally not connected with a portable cord. However it is possible that for the 2005 cycle this equipment may be proposed to be included.

Re: Arc Fault in bedrooms

Tom, since I have already wired this house with the dedicated smoke circuit and the bedrooms with AFCI,can I put all the smokes on an AFCI circuit brkr (approx 10 smokes).This would cover the requirement for the bedroom circuits. Of course I would only do it if the AHJ says anything about it. He's already passed the rough in inspection.

You can put all the general purpose circuits on an AFCI if you want. It may come to that in a few code cycles. I suprised the AHJ didn't catch it, or perhaps he/she didn't feel it was important to have on an AFCI...

I will support the AFCI concept when the sensor units are plug in, like the modular wiring method.

The units must have supervision with visual indicators.

The present method will soon be, a panel, with a lot of expensive breakers that do nothing.

Re: Arc Fault in bedrooms

There has been a lot of discussion about the smoke detector circuit on the AFCI circuit(s). Understanding that State and local AHJ are all over the place on this, I refer to the 2002 NFPA technical meeting ROC's #2-74a and 2-77.
The submitters of these comments suggested that "the smoke detector .....shall not be supplied by any circuit protected by arc-fault circuit interrupter(s). The reply from the panel was to reject the proposal, stating "there has been no data submitted substantiating why smoke detectors should be deleted from the AFCI requirement.
Further arguments, in at least some parts of the county, point out that some State codes do not allow separate circuit for the smoke detectors and that NFPA 72 requires the sinlge station detectors to have battery backup.
All that said, our local AHJ's have taken the position that the smoke detectors are not to be installed on the AFCI circuits. Given the NEC panel response and the UL test I would tend to disagree with them on this one. I would not want to try to defend their position in a court of law or a civil action.
 
Re: Arc Fault in bedrooms

I far from being the sharpest inspector out there but, can someone out there explain why they are worried about the smokes being on the AFCI circuit?

Here in Indiana the state AHJ feels that with battery backup the battery is still removable and can be removed in some smokes without the beep going off. this will leave the smokes disabled opon the failure of the AFCI, Which would be the first thing to trip in a fire. He said that when they come out with smokes with a perminit battery back up like a rechargable battery that could not be disconnected by the homeowner then there would be no problem.

Which brand of smoke detectors doesn't beep when the battery is low or removed? I know BRK and Firex do and I'm sure any detector that doesn't is not listed. The homeowner would never know when the battery is low.
 
Re: Arc Fault in bedrooms

Thanks Curt, I was quite sure that was the case and wanted to have someone else make that statment. I'm sure that the older smokes would not be used on a new circuit that would have AFCI but I guess it could happen. Once in a while I get a homeowner doing his own work and he gets a special deal on smokes without back-up and I make him take them back and tell the people at the "Depot" the inspector won't approve them.

guyg,
Unless you have a dual listed AFCI/GFCI, you will need GFCI(s) for the bathroom receptacles.
