My charger started popping its 30A breaker even while it was only charging at around 10A. I traced it to a push-on connector on the breaker that had slacked its tension and/or slightly corroded, causing a hot spot that would trigger the thermal shutoff in the breaker after a while. I suspect that the same happened to you: one blade of the fuse or holder corroded or lost spring tension, causing a hot spot, resulting in melting.
Always when charging at a new outlet, I monitor plug and outlet temp after several minutes and after half an hour for that same reason.

Has anybody ever melted the plastic and holder of an Automotive ATC fuse, without blowing the fuse itself? I had a cheap AutoZone in-line fuse holder with a 30 Amp fuse on the 12 volt line between the DC-2-DC and accessory battery, and today one side of the holder and one side of the fuse melted and made a nasty burning smell while I was driving down the road. This was especially concerning with my new Leaf Modules just recently installed ;> I was actually quite relieved to find it was "just" a melted fuse. The funny thing is that the fuse itself didn't blow, it still has connectivity when I touch inside where the leg used to be. The only thing I can think of is that while I was moving wires around for the install of the new charger the fuse got slightly jolted and one leg had a loose contact with the holder, causing a high resistance connection and lots of heat without going over 30 amps.
