My wife is always laughing at me because she thinks I did a little too much "learning on my own" electrical courses. I think I still have the nervous tick.
Seriously, it is an interesting question. I have not learn of any courses that addresses the new 4th Class requirements for training in electrotech. As a matter of fact I am interested in finding out whether or not there even is a marine electrician course anywhere, I don't think there is because I have not seen standards for that.
I am not sure how deep into it they get; but Malaspina College (http://www.pr.mala.bc.ca/nautical.htm#BME
) in Nanaimo, and Marine Education Associates (http://www.maritimeeducationassociates.com
) has put together a course that meets the "alternative path requirement" for fourth class cert from Transport Canada. They list electrical, but I am not sure what exactly is this course. and whether or not you can do it by correspondence.
Other than that you can try your community college for millwright, industrial electrician course, perhaps they have intro courses or beginners... Then again its probably too much for the average person, without being in an apprenticeship.
