I don't know, but I hope, since there will always guys like the OP doing that, they train the electricians in the field to beware.

You would hope they are taught to do a 120v measurement with a handy-dandy gizmo before exposing themselves to deathly zapping. Not to excuse the OP, et al, for doing that.

I believe it's SOP for a lineman to scan the hardware he's going to work on before any contact to see if anything's energized. Of course, how's that going to protect him when Mr. Resident decides just after that to power up.

FWIW, I have a customer that called me one night to assist him to connect a wall oven. He had already tried to wire it up but had blown the transformer in the street and three of his neighbors didn't have power, either. I'm still trying to figure out how he did it.
