career, all who said they do not normally check the internal wiring of equipment they install unless they're specifically asked (and paid) to do so. My employees certainly never did. I am not an attorney, but I would hazard a guess that such inspections may even be inappropriate without the owner's express approval.
2) One of my points was that the green conductor was never checked to see if it was, in fact, grounded before using it as such. The several electricians I queried replied that they seldom verify that the green conductor is grounded unless some unusual circumstance dictates it. A couple of cases like this have helped convince me to carry an electric field detector “pen” and to use it, even on green conductors. I suggest the same to everyone who works around electricity, especially amateurs.
3) You are correct. The state license in Florida is a license to be an electrical contractor. Prior to the Florida state licensing law, local jurisdictions issued (and still issue) certificates of competency. I received my first such certificate from Hillsborough County in 1972.
