The NEC has NO authority whatsoever, UNLESS the State adapts it as law with or without amendments. It is the State that vests the AHJ with 'authority' not the NEC. Government 101. Furthermore there is the overriding Federal Law of OSHA that SPECIFICALLY lists NRTL that are acceptable and lists the type of equipment that MUST have such approval. So if there is a UL approved apparatus listed for the appropriate Class, Div, Group, etc. by UL for a Classified location I just simply do NOT see how an AHJ can reject it.
Furthermore, if you are truly saying that and AHJ can reject a listed equipment for any reason, meaning that reason
- does not have to be based on either a technical explanation that is in the NEC, or
- an exception codified by a State amendment that is lawfully codified,
- (Not to mention that the NEC takes exception of trying to aplpy its rules to assembled equipment. If that would be the case hardly ANY assembled equipment internal wiring would meet the Ampere rating of conductors.)
Then the democratic lawful process is thwarted and is Constitutionally challenge-able for its arbitrariness.
