Re: OT it looks like two outlets in one of my rooms arent grounded
Well, apparently I'm failing to remember those classes, and that's fine, I'll concede.
You're still not addressing the only point I tried to make in this thread - that MOV-based surge suppression on an ungrounded line is doomed to fail repeatedly - which spells doom for your UPS system, and a much higher aggregate cost over actually having a professional rewire the plug with a ground in the first place.
