I'm installing an APC 3000xl rackmount UPS. I need to have a special outlet installed because the plug is a three pronger like I've never seen. On the end of the plug it says 125v, 30 Amp. When I called an electrican they thought I was crazy when I said 30 AMPS. I see nothing about AMPS in the documentation or anywhere on the APC website. Is this correct? Where else might I looK? I'm 'electricity stupid' and thus why I don't play with it! Thanks in advance!
