lmfao if your power goes out at new years when you are drunk in eastern europe that can happen
or like super drunk, and there is a useless switch around... convinced you got the right switch or forgot about the other one, then you think the power is out so you go fuck with it
that wiring might be off too, you know it could have gotten spliced in with some weird shit, old mig parts from 1967, etc.
but it does show you how insulation choice is important when low skill operators are likely to be present.
