Glad the information was helpful. I figured Eaton GFCIs would be good quality stuff, since usually Eaton gear is pretty top notch. I suspect the Gen 1 UMC did test, just less aggressively or something. The same Chinese GFCI I had problems with on the Gen 2 UMC, would also pop when trying to charge my Roadster back when I had it. I suspect the new Eaton GFCI would have probably fixed that situation as well.
