The strangest thing I ever found was my hand inside a live 3-phase distribution panel, touching the 'blue' phase
Long story short, when I was an electrical apprentice back in the late 80s, and health and safety being a LOT different back then, we use to do a lot of commercial and industrial electrics which had to be done 'live' on some sites as production lines could not be shut down.
We were working in a textile factory in Peterborough one day and I had to do some work on the 3-pase (415V) dissie board. There was some racking in front of the panel that I had to get on to get into the electrics. As the racking had wooden boards that I was kneeling on, and wood being an insulator, I was not too worried about it. Unfortunately for me, like a dingbat I rested my chin on the METAL framework of the racking, just before I reached into the electric board and just glanced my right hand on the 'blue' phase busbar.
Didn't half make my teeth chatter as 240V went through my hand, up my arm and to the metal framework via my jaw.
Sooooo funny now looking backl
