I have a 2017 Mitsu EVSE which is a Yazaki model 9482A128. It worked fine for about a year and now about half the time I plug it in I get a ground fault.
I've plugged it in several locations other than my house where I know there are good grounds and I get the same behavior.
I figured I'd try to open it up and check the wiring to see if it looks solid. I removed all of the screws and carefully used a screwdriver to pry it open but it is not opening easy.
Has anyone had any experience opening one of these?
Or any other advice?
