Here in NJ the state will adopt the NEC, but they will make a few changes. The state doesn't change much and some of it is very small changes. For example, the state will remove the wording every where in the NEC where it mentions the AHJ and instead insert, "The electrical sub code official". That is a minor change. A major change is that the state does not require the use of AFCI's yet. Also we are still working on the 2002 NEC right now.
