Just a reminder to make sure the UMC is snug when plugging into the outlet. There shouldn't be any play when plugged in. If you don't have the Tesla recommended NEMA 14-50, (Hubbell/Cooper), minimize plugging and unplugging the UMC. This outlet was installed about a year ago, the loose connection between the adapter blade and the outlet caused the adapter to melt into the receptacle. The circuit breaker save the day. Hope this helps someone.
