Plug Adapter on my Universal Mobile Connector has melted...

Yes, they use a simple resistor. I doubt there is much interest in a TT-30 adapter. Even if the Model-S would charge at 24A on 120V, it's still only 2.88kW, which is damn slow. Most all RV parks that have a TT-30 are going to have a 14-50.

Looks like I'll need to get my UMC replaced as well. I went to unplug it after topping the car up before a trip and I nearly burned my hand. The adapter and the cable between the adapter and electronics box were very hot. I've got some discolouration inside the adapter but it doesn't look like it's started to melt yet.

Glad I found this thread... We've been having trouble with my circuit breaker tripping. Car not charging... My electrician was over 3 times! Everything except the wire was replaced. Now he felt the right-angle connector and it was "burn your hand" hot. Called SC and will have them replace. Will dial back the amperage....
