Has anybody ever melted the plastic and holder of an Automotive ATC

Two possibilities occur to me:
1. Fuseholder not rated for the current. 30 amps is pretty high for a
simple quick-connect type terminal. You normally don't use them above 15
amps unless they are specially made for more, or have good cooling.
There's a good reason that high-current fuseholders are made of
bakelite, ceramic, or some other non-meltable non-combustible material.
Low-current ones get made out of cheaper meltable plastics.
2. Fake fuse. Some outfits sell really cheap no-name fuses that are
basically just any old piece of scrap metal in a fuseholder. Who knows
at what current it will blow (or *if* it will blow at all).
