Just an observation here ....
Many electricians are surprised at all the area the term 'electrician' can cover. The vast majority of codes, licensing regulations, etc., are directed towards electricians who construct permanent electrical systems. (Having a few pages of the NEC addressing 'temporary' electrical work is not going to change this).
One area is that of industrial 'maintenance' electrical work. Another is the work of 'stage electricians.'
Look at the credits of any film; did you ever wonder what a 'gaffer' was? He was the lead electrician, and with the training and experience to make him a 'master' by any standard. He's a 'real' electrician; he just belongs to a different union.
As for 'following codes,' I think you'll find that the trade practices of the stage technicins are far beyond anything OSHA or the NEC can imagime. "Temporary" work on the scale of a movie set or rock concert is a world of its' own.
