And if you've gotten away with something before, you're like the cat who has used up 8 of his 9 lives running across traffic, about to do it again. I've gotten zapped by 480 VAC at what should have been several times a safe distance, which made me FAR more cautious even working on household 220 down to even 5.0 VDC (yes, back in my college days, I turned into a conductor for a hi-current 5 VDC power supply that definitely got my attention. My hand hurt for several hours after!) High Voltage electricity is a very unstable, unpredictable ally, not really a friend.
