Never mind, I noticed that the upscode2 driver doesn't seem to support this command (yet), so the chances that you actually did a runtime calibration are fairly slim (unless you used something else than NUT to control it).

Nominal load depends on the amount of VA (or W) that a UPS sees. It makes no difference if this is one load drawing 2.2 kVA or ten each drawing 220 VA, the total load will be the same. Surge (inrush) current is something different. Usually, PC/server power supplies will peak around 20..50 A (each), with essentially no dependency on the actual load. So there is a huge difference if you have one or ten systems connected when it comes to inrush current. In many cases, five PC/server power supplies all connected to the mains at the same time will be enough to trip the circuit breaker. Adding just a single additional one may tip the scale. When it comes to tripping fuses, you may be fine if you stay just below a certain limit and will only notice a problem if you (just) exceed it. So basically the only way to check for differences, is to disconnect all loads. Don't leave the mains connections attached, the power button on a PC/server is just a soft switch, it doesn't actually disconnect the mains.
