Re: WATER HEATERS
Bill, I'm not being arguementative to piss anyone off, only for the sake of aruing one side as a way to learn. I can jump ship and argue your side as well, but you're doing a fine job
more your first question.
As to your second, I think anyone could be smart enough to do it, but not everyone should.
I work in one locality that has a law that if you are caught doing electrical work without a license, you go to jail. Do not pass Go, do not collect $200.
And hey, let's face it, anyone can be smart enough to pass a test, but does that even really mean that the same person has the ability to do the work??
I know an electrician, took the test, and goes to continuing ed. seminars. He called me the other day about a hot tub hook-up. The tub was 240v 2-wire plus ground. He installed a 2p.50a. breaker in the main panel, ran a 6/2wg to an outside disconnect mounted on the wall of the house where he installed a 2p50a GFCI breaker. He went from there to the tub in pvc with (2)#6 hots and (1)#6 ground. In the disconnect he 'floated' the grounds with a split bolt.
Getting the point yet?
His call to me was that the Spa supply company sent someone out to check on the tub. He didn't like the way the electrical hook-up looked, so he called his own electrician to check it. Spa co.'s electrician told homeowner that installation was not safe. (it had not yet been inspected).
This
Licensed Electrician actually hooked the white wire from the GFCI breaker to the unbonded neutral bar in the disconnect, but never brought a neutral from the main panel. He told me that was how the INSPECTOR told him how to do a 2-wire hot tub. I don't that I believe that part.
He didn't know what to do and called for my advice. The spa co.'s electrician told him that he would have to run a 4-wire to the outside disconnect. I told him to swap the 2 breakers. I don't like the GFCI outside anyway. He did and he passed the inspection.
I'm not 100% convinced that the piece of paper means as much as we would think that it should sometimes.
I don't know it all, but this to me seemed to be rudamentary.
