Is it possible to contact the NFPA Authority Having Jurisdiction about the NEC and if so how?
Yes, in fact it is important to contact the AHJ about the NEC if
there are any questions on how it might be locally interpreted. The
local rules will determine if there is a fire inspector, building
inspector, wiring inspector or the state fire marshal's office that
would be the appropriate AHJ for your facility. You could start by
calling the local building officials who issue permits.
