Our local AHJ requires all new equipment installed to be inspected regardless of who does the wiring. And beleive it or not we are in the state of PA! And I must say we have no fear of them because in our facility we pride ourselves in having everything up to code and will hold up our work against any contractor's work. In addition to the electrical inspector, We get Dept of Labor & Industry, OSHA and DEP in here ocasionally and have never had a bad experiance with any of them.
I'm not saying any of this to boast but only to say that there actually are places that run by the code. These are the places that electrical contractors never see because they have no reason to be in such places.
