Re: lighting
In my opinion, the AHJ should have the final word, but it should be covered by either/or. I feel it should be covered by the NEC as long as it is served from the building service. If it is served by the utility, then NESC should take care of it. The problem I see is that if the lighting is owned by the buidling and the NESC does not cover it, something must be in place to regulate it. If it is unregulated, then anything can be done and/or built.
In our case, the AHJ sets the guidelines as to the design parameters, requirements, etc.
