I used to do volunteer plumbing work for Habitat for Humanity. Some of us studied plumbing and some of us studied electrical for a couple of Saturdays at the local trade school, then we worked under the supervision of a real plumber or electrician. Then the local building inspectors decided that non-licensed volunteers could no longer do electrical and plumbing work. My dad said I should file for an apprenticeship with the state labor board and then I'd be able to continue. If I did enough supervised volunteer work, I could apply for a license. I never looked into it because I didn't like the idea of probably having to pay dues to a labor union just so I could do volunteer work. This was maybe 5 or 6 years ago.
I just found out today that my electrical engineering degree should qualify me to skip the apprenticeship and take the exam to get a "Master Electrician A" license here in Minnesota. If it was a BSEE I *know* it would qualify (according to the state's licensing FAQ.) I have a BSEET rather than a BSEE, but the actual statute is less specific than the FAQ and my degree should be OK.
I think I'm gonna look into it. For one thing, it would be nice to have a skilled trade in addition to my profession if my employer decides to start laying off middle-aged technical folks again.
Best regards, Bob
