NJ, has adopted the NEC "As Ammended" just like any other state does. So I guess that Nj is just using the NEC as a guide line for their own code. Shockme, I hear rumors that the 2005 will be adopted real soon, but you know how that goes. We will just have to wait and see. As an AHJ, I am asked that question all the time,, but I don't know the answer. My elec. contractors Assoc. sometimes get more info before I do.
