I have a rackmount UPS. The UPS has a 6ft long 12AWG thick power cable that powers it from one of the server room's 20A wall plugs.
The current orientation of the cabinets is not ideal. All but this one are easily moved, however this cabinet's UPS' cable is too short to reach one of the 20A circuits if I were to move it.
Is it acceptable to attach the UPS's power cable to a thick (12AWG? or thicker?) extension cable? I'm no electrical engineer, but I think this will add impedance at the two cable's junction (ie. the plugs). I don't know if I should worry or not. Having an electrician come out and re-due the cable on the UPS is really not an option.
I know people generally don't recommend daisy-chaining surge protectors (even though it will work for most cases), but surge protectors are doing a bit more than just a plain cable.
(please don't just say "no don't do this!", please explain why, the risks, pros and cons.)
