Reno:
Here in Nj (as it now stands) we use the '08 NEC with some amendments, HOWEVER...the '05 (as amended) is 'the rule' for any rehab work. AFCI is not required for service change, panel change, or work within an existing structure. AFCI is required in new construction, and any additions. "Addition" is defined as an increase in volume. An exception to this is IF existing circuits are 'extended' into the addition area.
After you digest the above....
Soon (not my word) the State will update the Rehab portion of the UCC, and rumors abound that the AFCI requirements will be modified to include 'new work'.
Now that I probably added to everyones confusion...I have to go back out in the rain
