Youtube has plenty of clips showing various critters caught in the act of trying to short 2 adjacent overhead power lines.found the remnants of a squirrel(fuzzy tailed rat) under a transformer pole. 14.4 kV! it looked sorta of squirrel like still, but up close it was just a piece of black charcoal. a very un-natural end for the rat with a pretty tail.
Most of us have survived 120 volts. It isn't comfortable, but it doesn't explode when you make a mistake!I think its a good idea to lower the voltage to around 120V (is it safe enough?).
Always liked that clip and used it at work for safety lectures.This is slightly higher voltage but the same effect can be imagined with 415 vs. the 480 3-phase here. I have a screw driver in my maintenance dept that was dropped across some similar power sources - not much left. A small slip of a screw driver, or a poorly tightened lug can cause some major damage in a fraction of a second. By damage, I don't mean the building.
