I'm getting a 25*F uptick at my blink handle with 16A at the 1 hour mark. Haven't checked my Open EVSE (Leviton) handle yet.
I don't agree, it was Blink's engineering that specified a crappy low-cost terminal block. It's a marginal part for 20A, let alone 30A! On top of that, it was not installed correctly.
Several people personally inspected Berman's unit, I was one of them. One of the factory screws was not very tight, and the middle one was loose enough you could actually see a gap in-between the pressure plate and the conductor. I'm not even sure it was tightened at all. I think this is what started it down a path of overheating. The overheating looks like it eventually carbonized the plastic and then an arc-over event occurred on the input side.
This is the factory side, which looks to me where the problem began. The middle screw was not tight at all. You can clearly see the gap.
