My dad was doing some experimenting with the UMC to discover how it determines which adapter is plugged into it. The goal was to get 24 amps from a 120V source without buying the proper adapter from the Tesla store. It turns out that the two communication pins (shown in the picture below) have a resistance across them, and this resistance tells the UMC which voltage and current it should look for.
Drill till you get an open between ground and sense. Adjust the pot to 30k Ohms and it will take 120-240vac at 24amps.
What do you guys think?

It's not just in Tesla-land, it's everywhere. Read electrical or construction forums, someone asks "can I do this?", the reply from experts is "that is against code and would be extremely unsafe", and then that someone begins to argue how it's not really unsafe and the code-writers are secretly agents of <his-hated-political-party-here>. All the experts can do is note that there are insurance and liability implications, strongly warn against it, and pray the poster doesn't lose his life or the life of a family member, or his home.
