Not believing him, I reached over and touched it myself. Sure enough, the metal casing was hot. I had recently hooked up a UPS (Uninterruptible Power Supply) that is basically a big battery that keeps the computers on when the power flickers on and off. I had noticed that there was no grounding pin when I installed it, but I did not have one, and I don’t have a car, and if I had a car I would not know where to drive to get one. So I installed it without grounding the system and figured everything would be fine.
Obviously it wasn’t.
So I made do with the materials at hand – a paper clip. When I went to “install” the paper clip, I unplugged the UPS from the wall because 220v still scares me. As I was working the paper clip into place – and trying to simultaneously answer the phone – I yelped as 220v passed through my fingers. It turns out that even if a UPS is not plugged in it can deliver 220v because it is, after all, a big battery designed to do just that.
By the way, the paper clip is working out great.
