OK, my tale of ancient electricity. Early '80s, NCR minicomputer (size of a large refrigerator) installed 3 feet in front of main breaker box to computer room. NCR was on site doing maintenance work inside the computer so skins were off when the electricians decided they needed to do some work on the breaker box so they had the front off it. Whatever they were doing, they managed to drop one of the live street feeds out of the breaker box and it fell into the open computer, striking the back plane. 3 inch long black burn mark on back plane, and fried all but 1 of the logic boards in the machine.

The body was discovered after a while by odor, and people thought he could not be removed safely without cutting off power to about half the datacenter. I remember managers asking us what was connected to what so they would have an idea of what servers would go down, but I can't remember if they eventually removed him by shutting down power or by just being very careful. The big guy was laying right above some 3-phase copper cables that were each about an inch in diameter - possibly the lines coming directly from the power company.
