Good reply, I am an electrician and the receptacle that’s is used is a 20 amp dedicated circuit. You are correct regarding the stab lock terminals on receptacles. These should be banned by the NEC, no one should use these for anything. The plug itself does get very warm but the fault that shuts the charge down shows up as a car fault most times. The faults did occur some in the spring but since the summer is here I may have to disconnect and reconnect as many as 8-10 times to charge the car.
