We recently installed some new blade servers and we have 'overloaded' our current UPS (APC Smart UPS 3000). We bought an identical UPS to balance out the load, however, we did not have another 30 Amp socket in our server room to support it. I have been asked to figure out if it's 'safe' for a 125V|30A plug (with an adapter) to be plugged into a 125V|20A socket. I was told to calculate the 'draw' power of the UPS and to check the spec sheets, but I'm completely new to this so I'm not sure what I'm supposed to compare/calculate.

If someone can point me in the right direction (even reading), that'd be awesome!
