APC says you can even put a 15A plug on a 2200
You left a few bits out. APC says this only
about the exact model SU2200NET and then only
if you limit the load to 1200VA. All of the other APC units must have a 20A plug. And all of these, the 2200NET included, must be on a dedicated circuit. Note that the 2200NET ships with a 20A plug because a dedicated 20A circuit for this UPS alone is what is required in most applications.
Like I said before, it is pretty foolish to spend money like this for UPS equipment, and then have the circuit breaker trip and dump your IT load.
What are the model #s you are using?
What are the nameplate ratings of your UPSs including amps, VA, and W (or kVA & kW)?
What the peak load of your IT equipment in W (or kW)?
