I officially installed my first AFCI today. When I tested the receptacles with my Ideal tester it tripped the AFCI. Also when I checked the voltage to ground it also tripped. Is this normal operation for these new paragons of safty.???
resqcapt: Hmmmmmmm ? I wasnt aware of a GFP function, Yes the Ideal tester has a coil in it, I figured some type of inductive loading, or kickback. After i reset it I had the carpenter plug in his electric planer and it worked fine and then told him to turn the switch on and then plug it in and it worked fine again, so maybe that's it, other than that it worked great. Maybe now I should read the instructions ?? Ha ha ha........ You know what they say if all else fails read the instructions.
And I was getting ready to say "It was only a matter of time..." but since it holds under load and under switching (yeah, I know, switching is a series arc) then I'd call it good.
By all means if anyone has trouble with AFCI's "nuissance" tripping, then please report here about it whether you've solved the problem or not... We all need to know as soon as possible, to help combat the inevitable.
Steve, (sparky) you've still had mostly good luck with 'em?

I'm doing work on a pre-fab home that was delivered to the foundation after Jan 1. In addition to the basement, garage, HVAC and gameroom wiring, I had to replace three regular breakers with 15A AFCI breakers. The circuits that the breakers feed are not strictly bedroom circuits but a bedroom along with a bathroom or a utility room (laundry) or the living room. Evidently, the home designers weren't thinking AFCI or 2002 NEC when they built this home. I've had two problems so far. The first was an AFCI that tripped whenever an under-cabinet fluorescent light fixture mounted in a bedroom clothes closet was switch on. I took the fixture apart and made sure that none of the solid conductors inside the fixture were near sharp metal edges. I also found that one of the lamp sockets was broken with the plastic missing from part of the socket. This was the side of the socket that was near the metal case. I applied strips of Scotch 88 to the case to prevent arcing from the socket and the breaker no longer trips. Another AFCI breaker trips apparently for no reason and will not usually reset. I swapped circuits with an adjacent AFCI breaker and that one did not trip. I suspect the breaker is defective and will attempt to return it to Cutler Hammer.
