Whats black and crisp and hangs from the ceiling?
An Irish electrician
Been there done that, once or twice. In America, we use 120 V for most plugs and in commercial and industrial applications, we often use 277 V for lighting, though you can also encounter 120 V lighting, as well. I've been hit by 120 V so many times it feels only like a nerve twitch. 277, however, hurts and gets my attention.
I once took 120 V across the chest for about 3 seconds. Anyway, now my unit glows in the dark and I don't have to turn the light on to pee. Old electricians never die, we just can't find our shorts.
