15 Amp 250 Volt fuse in a 13 Amp, 120 volt system. Onle one end of the fuse was heating up, and the plastic part of the holder melted. The fuse blew. I thought maybe the fuse blew because it was old, and that melted the holder. But after cleaning up the clips, I put a new fuse in and the one end of the fuse started heating up and sparking again. I flipped the fuse around, and the other end of the fuse started heating up on the same end of the holder. So I flipped the holder around. Still the same end of the holder. I tested for shorts, but there were none. It was still pulling 13 amps, as expected. I installed a new fuse holder, which is NOT heating up. It's working fine with the new fuse holder.
So what would cause that to happen? Does plastic get old and become conductive? I know there's no metal in the fuse holder.
