Ryan, What a question you ask. I've seen quite a bit over my time as a Faultsman. I've seen people put nails in pole fuses on the load sides of Xformers to keep the TV going during Rugby games, only to have the line-side drop-outs fail, about 3 seconds later. At least these people have the sense to use Insulated Pliers when putting the "fuse" in. But, things on the inside of a house really amaze me, I've removed old porcelain fuses in older houses, trying to find Faults and Meggering the installation, only to find 80A or more, Tinned Copper Wire fuse links in the fuseholder, these don't tend to co-ordinate too well with the HRC pole fuses we use here.

I was working in a small town once with little industry. We were about it. The local vet called for her electrical contractor from 'the city'. She passed the phone to him and he explained the situation. X-ray machine had a blown fuse, hurt dog waiting for the use of it, 30A oddball from Europe, 2 1/4" hole center, non-time delay. I measured my inventory and all I had were re-usable links, no cases. The truck arrived just as I finished drilling the holes. He screwed them in place (no cases) in open air, and closed the cabinet.
Any pennies behind blown fuses? American pennies ($0.01) are about 2cm diameter and made of copper and lately copper clad zinc. People used to stick a penny in a screw in fuse holder and reinstall the blown fuse on top of it to get the lights back on. Of course there's no more overcurrent protection anymore....
A bullet!....Read this in Car and Driver magazine many years ago....A guy with a pick up truck was in a jam and needed to replace a burned out fuse in his pick up truck (the fuse box was located under the dash by the steering column) and used a bullet to replace it. Needless to say, he was in the hospital getting his left leg repaired because it went off! Was this guy brilliant or what?
