John,
The last letter I got from the local IAEI chapter had a note in there from Susanne. It says "...I want to clarify that any work done in an existing building or dwelling will comply with the "Rehab" code as presently written..."
So in MHO it sounds like the arc fault is not required yet even if the whole house (which is existing) is gutted and rewired.
I can also see why other people get confused when they see that NJ follows the NEC (sort of) Our state will adopt the NEC but likes to adjust the code to meet our states needs. ( Be it for better or worse).
