My issues are occurring with the 18' foot cord. I received it early June 2020, so it's from their 3rd batch, I believe.I just read that thread for the first time. I have the long cord, too. It would get warm but not “hot.” But aren’t people seeing this issue with the shorter cord too? I wonder if the new units they are sending us are different in any way (thicker cord?).
Also, I saw some voltage drop, too. Looking at my screenshots, I see 234V at 48A and 238-239V at 24A. But I figured that was partly due to the long wire run from my breaker box to the charger (about 60’) or that it was just normal. Touching the 60A breaker the electricians installed I can feel some warmth when the car is charging. But it is not “hot,” just warmer than the other breakers. I know essentially nothing about electrical equipment though. And like everyone else, mine worked fine at 48A until mid-July, then this issue started happening every time.
Tomorrow I’ll try 40A but I’m superstitiously afraid to jinx the 36A which is working well right now.
