Re: Arc Fault
If your working under the 2002 or 2005 NEC the light fixtures must be AFCI protected in bedrooms.
Yes it will work.

Re: Arc Fault
what year code are you on? Think about the lamp you will plug in.Yes under 02 and 05 all outlets.That includes lights,fans,smokes and receptacles

Re: Arc Fault
I did have a problem with an electronic controller for a fan - a combination three speed fan switch and fan light switch. The response I got from the manufacturer [Lutron] may be seen here:

Re: Arc Fault
Of course you could be living in a state like Indiana which re-entered the word "receptacle" as it was worded in the "99" code cycle. so we don't have to protect light's or smokes.

Re: Arc Fault
I can't understand why some jurisdictions want to prevent smoke detectors from being installed with AFCI protection. In order for the AFCI to kill power to the smokes the circuit would have an arc fault. If this is the case, it is more important to prevent the fire than to alarm the fire. Smoke detectors are required to have battery back-ups in our area, and the manufacturers instructions say they are to be tested periodically so they should still work if the circuit has been deenergized. The only reason I can see for exempting smoke detector circuits is if AFCI's do not work. If they don't work, then don't require them anywhere, if they do work, use them on smoke detector circuits!

haskindm,
I would agree if I believed that AFCI would really prevent most electrical fires, but I don't. In my opinion most electrical fires are the result of high resistance connections (series arcs) which AFCIs do not directly detect. AFCIs only responds to this type of fault after the heat from the high resistance connection has caused the original fault to progress in to a line to neutral fault, a line to ground fault or to a neutral to ground fault. At this point in time the AFCI does react to open the circuit, but an smoldering stage fire may alread exist...it will be minutes to hours before this fire makes enough smoke for the alarm to react.

Re: Arc Fault
Hold that thought for another 30 months or so. That will be your next opportunity to submit recommendations for changes for the 2011 NEC.

Re: Arc Fault
It is my understanding that the new combination type will respond to series arcs. I am not exactly sure what the specifics are, but I was told this by a freind of mine from UL.

Re: Arc Fault
I've heard the same thing, however I have also heard that a few of the manufacturer's are now calling series arcs what they were calling parallel arcs. So there is really no change. And what about glowing connections.

Re: Arc Fault
Ryan,
As far as I know the only difference between the current and new AFCIs is the point where they start looking at the arc. The current ones don't look unless the current is 75 amps or higher, the new ones start at about 5 amps. They can't really look at "series arcs" because there are too many things like switches that create series arcs in normal operation.
