I opened my garage door today to smell burning - plastic, or wires. After searching the garage door opener and all of the obvious locations to me, i decided to check the 240v outlet at the back of the garage dedicated to Tesla charging, which, at the time was in use. The Tesla charging cable was hot to the touch, so i unplugged it to find this. I'm pretty sure this was a wiring issue on the 240's side, as the charred bits seem to be from the 240v plug. If anyone else has experience with this, let me know!
