I purchased a wall charger when I got on the reservation list and installed it last week when I ordered my Model 3. I have it on a 100 amp 240V dedicated breaker. I metered open circuit between L1 and L2, and from L1 and L2 to ground. The ground meters short to the ground bar. A short while after plugging the charger into the Model 3, all of the AFCI's on other circuits trip. It has happened the three times I have charged. I used the 115V adapter last night without any problems. I know that I can replace the AFCI's with GFCI's or regular breakers, but I think that would violate my electrical code. Has anyone experienced similar problems?
