"Legal," "get away with," and "right" are three very different things.
Ask yourself this: Is it OK for you to practice medicine or law using another persons' license? Drive? Buy a gun? Buy alcohol or tobacco? Write a check?
Why would and electrical license be any different?
Yes, it seems like a no brainier.
Yet, here in Saskatchewan I know of a journeyman electrician who is employed full-time at a company and has a contractor's license. That is not supposed to be possible based on the rules governing who is allowed to have a contractor's license.
So how does he do it when no one else can? Apparently he found a legal loophole. I don't know the exact details but I've been told that he uses another electrician's license # on his permits. The other electrician supposedly has agreed to this practice. Is this true? I don't know. Which is why I've posed the question.
