I have 2 80kw UPS systems, powering a total load of 80kw. the load has duel power inputs so when both ups's are on line they each are running 40kw to load. If one fails, the other runs the entine load so it is outputting 80kw. is my service caculation here 80kw or 160kw? My guess is 80 if i supply both with 1 breaker sized for 80kw, and 160 if i use 2 seperate breakers to power them. Question 2- if i have a ups with a nameplate rating of 80kw and i only install 40 kw worth of batteries to fit the current load of 40kw can i treat it as if it were a 40 kw ups? john
