    For what it's worth, I've been charging my Chevy Volt using the 120V J1772 cord (that came with the car) for 10 months through a double GFCI setup without any problem. The GM charge cord has a built-in GFCI and I have it plugged into a garage outlet which was already GFCI protected.

    I also bought a portable GFCI adapter for travel use and used it a couple of times recently where it protected an extension cord leading to the GM charging cord. No problems there either.

    Hi TEG,
    On a recent road trip I tried at two separate locations to use my RFMC to plug into a GFCI 120V outlet, and in both cases, the GFCI in the outlet tripped when the contactor in the Roadster closed to start charging. I tried multiple times, and had the current limit set to 12A. Nothing worked. I had my standard Tesla 120V cord as well, but it would not fit the recessed outlet, so I could not try that. The standard cord also still has the original built-in GFCI, so I don't know if the double GFCI would have been more trouble anyway. Advice?

    I guess the RFMC doesn't have a GFCI so you weren't running into a double GFCI situation.
    It sounds like some PEMs had issues with current leakage causing these trips on some GFCIs.
    I am not an expert on this stuff, just an information gatherer. I guess you should double check that you have the lasted Roadster firmware, and ask a service advisor if they have any advice.
