Started heating my HLT up today and went upstairs while the water was heating. Went to check on it about 15 minutes later and noticed the smell of plastic in the air. Shut everything down, opened up the toolbox that holds my panel and a bunch of smoke comes out. One of the terminals is melting and probably would have started a fire if I waited much longer.
I'm using a pretty standard configuration. 30 amp breaker at the Box, spa panel, 5500W Camco heater element. Leviton 2626F 30 amp locking receptacle as well as a leviton 30 amp locking plug. Wires appear perfectly fine, not blackened.
Only thing I can think is I hadn't tested the GFCI recently, it failed and a terminal wire loosened. I've brewed around 7 or 8 batches without issue with this setup.
Any other thoughts about what might have happened and best way to rectify it?
