I have a 2020 Model 3 (just bought it used from a friend who took immaculate care of it). I don't use enough electricity to warrant installation of a dedicated charger, so I've been charging it with the Mobile Connector. The Mobile Connector, however, keeps tripping the GFCI outlet that I plug it into. It will charge a variable amount of time -- sometimes just a few minutes, sometimes several hours -- but will inevitably trip the GFCI outlet. Here are all of the fixes/causes that I've tried and/or eliminated:
- There is nothing else plugged in to the circuit that the GFCI outlet is on. It's a dedicated circuit -- I had a plug-in hybrid before the Tesla, and we installed the outlet specifically to charge the car and nothing else.
- The GFCI outlet itself is brand-new; I had an electrician come in and replace it just last week.
- The Mobile Connector is nearly new -- I took it into Tesla about 2-3 months ago for some other service, and told them about my problems with the GFCI outlet. They said they couldn't find anything wrong with the car's electrical system (although I don't know how hard they looked), but they gave me a brand-new Mobile Connector in case the old one was the problem.
- It is the GFCI in the outlet tripping, not the GFCI in the Mobile Connector itself or the actual breaker.
- I have lowered the charging amperage from 12 to 11, and then 10, and that doesn't seem to make a difference.
