We are replacing the controller and fire pump for a customer. Because of the size of the new controller, we have to relocate it about 10' away from the previous location. The AHJ wants us to use 2-hour rated conductors into the new controller. All well and good (although not necessary; once you are in the fire pump room you don't need the 2-hour rated conductors). We are on 2008 in NJ. The building was constructed, as far as I know, around 1985. I don't know which edition NJ was on then, but say the 1984 or '87. Article 695 didn't appear until 1996. Where would I find the information on the rating required for the conductors (if any) back then? I ask because the conductors from the disconnect on the 10th floor to the fire pump on the 17th floor are THW and wouldn't meet today's 2-hour or the previous 1-hour rating requirement. I want to know if I'm going to be the bearer of bad tidings to the customer.
