John, will figure out why I asked the question. It is because here in NJ we are getting ready to adopt the '08 NEC. I still don't think that the AF breakers have proven their reliability. Since NJ doesn't require them yet, I need some of the people out there who have used them. Right now NJ will adopt the '08 and use AF breakers on new construction only. We have a separate code for rehab houses. Anymore stories out there? I would like to know them. Thanks.
