I remember going to change one of the 65V power supplies at a cabinet one day!
There is a 3 core mains lead for the mains input and a seperate earth bonding wire, the power supply was just thrown on the shelf (typical ntl) and I had a little belt and used a few bad words when I lifted the still powered PSU to make room for the replacement. Unfortunately the contractors had mixed up the Earth and Neutral connections on the mains socket fitted to the backboard of the cabinet. It was very fortunate that I had not removed the extra earth wire from the unit, or the shock could of been much worse.
I powered the unit down, removed the extra earth wire and had a nice brightly lit neon screwdriver when I touched the psu case with it powered up again.
See, ntl were looking at ways of getting rid of network tchnicians in those days.
