I know this doesnt answer your question but I have found the pay for apprentices to be pretty lousy. Not to mention the lack of respect people have for trades people and the occasional boss that doesn't listen to new ideas.
Those are a few of the reasons I decided to get a degree instead of doing a full time apprenticeship.
Anyway, sorry about the venting. I don't want to discourage anyone from becoming an electrician because for all the bad things, it's still a good field and as long as people need electricity, the world will need electricians.
I still havent ruled out a career in this business entirely.
Here in New England jouneymen (+women) can make between $20 and $40 approximately, and alot of that depends on the union/non-union issues like Nick said.
