WE here in the Garden State here that AFCI's will only be required for new construction/additions/re-wire jobs, which is a blessing. As soon as they get around to adopting the '08.
IMHO, doing a service change/upgrade could turn into a nightmare......am I on the right track??
I heard a lot of cr*p when I did a '08 changes CEU seminar, guys were all over me regarding $$$, AFCI, TP/WR, etc.
Change is tough for some. "Guys, I don't write it, I enforce it!"
