I used to work 277v live. no more unless I have no other choice. Years ago I once was working On a 277v lighting circuit which I thought was de-energized. I had a ballast cradled in my arms while disconnecting or reconnecting it. I still don't know what touched what but what i do know is that baby became very uncomfortable in my arms. Talk about vibrating all over! I left it drop, baby, cradle, and all. That was probably the best thing that could have happened to me since at that time I had no business messing with electric, much less 277v as I now realize when I look back. I still shudder when I think of the stuff I pulled off back then. Now many years later I have become much more educated and experianced. But I am still learning. There is always room for improvement.
