It's not easy but then again it's not hard once you get the hang of things. I was going to a college class for that for a little while but I had to leave for personnal reason ( besides the point ) While I was taking that class we made switch boards learned how they work how to cut the power when needed um lets see we rewired a office building ( demonstration type of course ) we basically did every thing that you did while on the job but as for you, i don't believe you would be that much hands on at first. Once your use to it and your master thinks your ready he MAY let you do something on a house or something.
