I have the EVSE installed in the sun outside where temps can reach well over 100F.However, the circuit trips every hour or so when I try to charge my car. I have also tried charging while the AC unit in the house is turned off and that had helped reduce the auto tripping but not 100%. I had used an electrician to install this for me and he had come out twice to check and problem is still there. I don't want to spend more money on the electrician, does anyone have any pointers that could help please?

Thanks,
