DOH! So any idea what caused it? Have a short somewhere? Do you have a GFCI in your setup?

Well I assume it was just a poor connection that slowly got worse and worse over time. This connector hasn't been touched in about 2 years of electric brewing. Nothing shorted or caused a ground fault, I just shut everything down when I felt how warm that connector was getting! I do have everything protected with a GFCI.

This is so common that soldering on spade, fork, and ring terminals is the only foolproof way.

That is a classic example of a high resistance connection that either started loose or got loose, and then got hot.

I like the solder-on terminals idea to make a better connection with fine stranded wire.

How exactly could you do that? That type of plug has the screw terminal at the bottom of a fairly long plastic tunnel. Could you get a fork terminal down in there? It just so happens I just got plugs like this and was about to start connecting them and if there is a better way to do it now is the time for me to do it.

for those kind of connectors, it's not a bad habit to check the screw terminals annually or so and make sure they are all tight.

One could also "tin" the wires prior to connecting them in this style of plug.

Agreed.

A well-soldered connection is your friend.

It cracks me up how much high amp plug ends cost and how easily the cheap brass threads strip out.
