I started doing electrical work when I was 18 years old. I had been in the trade for about three months, and we were doing a remodel job at a office building with 277V lighting. One of the people I worked with required me to work on a live 277V J-box that could have been easily disconnected. He said "eventually you will have to work hot, so you might as well do it in front of me so I can show you what you do wrong". I HAD BEEN IN THE TRADE 3 MONTHS!!!
I think this sick S.O.B. just got his jollies on watching some poor kid get lit up. I had no business in that J-box. I would like to run into that individual again and have a nice "discussion" with him.
BTW, I didn't get shocked.
