Doc, I think you were pretty diplomatic here.
If this guy wants to misrepresent himself thats fine,(not really) but he shouldn't be trying to teach something that he doesn't understand.

You know whats going to happen here. When a problem occures this guy is going to hang Brian out to dry, and blame him for the faulty wiring.

Brian I know this a touchy situation to go above somebody, but you might mention your concerns to some one in a higher position.
