Tesla Motors Club
Hi All,
I took delivery of my Model 2 days ago. In preparation for the purchase, I had a licensed electrician install a NEMA 15-40 outlet powered by 50 amps in my garage. The circuit box, unfortunately, is on the other side of the house so he ran 6/3 MC cable across the width of my basement which was about 75 ft of cable. I purchased the Clipper Creek 40A EVSE as my charger.

My issue is that my breaker seems to occasionally trip (3 times so far) when I open the Tesla app while the charging cord is connected to the car. The car was not actively charging during any of these periods. I have done at least two charges without obvious incident and the app indicated the car was charging with 40 amps at roughly 9-10kW.
I searched the forum and several threads noted that having the breaker on a GFCI may not play nicely with the car. I believe the electrician re-used the breaker that previously was connected to an outside hot tub and I would assume had a GFCI. It seems like this may be what I should pursue but I wanted to get the community's feedback in case there is something about this situation that indicates a different problem.
