The jacket on the wiring should have the Brand along with size and type of wire and some have strand count. By the looks of the Burnt wiring as Ive seen over the years.. to me it looks like CCA wiring by the Charcoal burn color look. Not Sure on the size by the Pick but taking a Wild Guess that its 4gauge??

what can melt an amp fuse?

Most melting near connection points are caused by loose clamps (bolts, screws, blade holders, crimps).

I don't care for those type of fuse holders personally. Seems the set screws always loosen up and that will cause it to melt.

There are a few different things that can cause that. If you could fill us in with the system specifics, we could probably help you out better ...

Yes.

I've had trouble with those style fuses myself and as you say the bolts always seem to loosen up and cause issues. Some I've used aren't tapped deep enough for the bolt to really cinch tight in the first place and you'd need to use a washer right from the start.
