How did you identify the problem and get ComEd to look into it? My UPS is switching inconsistently, sometimes a couple times a day, and I’ve seen some signs that makes me think it’s not just that UPS/outlet/breaker. I wasn’t at the point where I was going to do anything yet but since you’re talking about the same provider I have I figured I’d ask. I have a multimeter, oscilloscope and smart plugs that watch voltage/amperage/power.
I’m with the other guy, I’m not reading that again, but I remember it was on the verge if that helps.
