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.
