Re: light over tub
It is not what I think, it is the authority that is specifically given to the AHJ by the NEC. 90.4 is pretty clear. The only person that may approve a piece of equipment is the AHJ. That is why it is important that we never refer to equipment as "UL Approved". Testing agencies do not approve anything, they list it so that the AHJ (whoever that is) may approve it based on their testing. If the inspector is the AHJ he has the authority and the responsibility to approve or NOT APPROVE a piece of equipment for ANY reason regardless of the listing and labeling. He may also approve equipment that is not listed. To avoid problems with inspectors making arbitrary decisions, the county in which I work has made the Electrical Board the AHJ. For 99% of the time this has no effect on the work done in the county, but when the electrician and the inspector disagree they can bring the dispute to the electrical board for arbitration. This has been in effect for about 6 years and seems to be working fairly well. If you do not trust the inspectors in your area you will need to work with the legislators to have someone else appointed as the AHJ. There are several areas in the code that give the AHJ a great deal of authority, that is why it is crucial that these people be extremely well qualified. Unfortunately in many jurisdictions the AHJ is whoever is available on that day. Sometimes that may be the plumbing inspector who is filling in for the electrical inspector who is on vacation.
In this case, if the inspector is NOT the AHJ, he has over-stepped his authority. If he IS the AHJ, he is doing his job. You may disagree with his decision; but he has the power, the authority, and the responsibility to make that decision.
