RE: OFF TOPIC: 2-prong outlets



Well, sometimes. Read the specs for your prospective UPS very carefully. 
"Consumer grade" units (ie. cheap ones that are generally used with PCs / 
comparatively low draw equipment) can vary wildly in exactly what you're 
getting, with not much upfront warning. "The Big Print Giveth, the Small 
Print Taketh Away" can apply in spades to cheaper UPSs. Some don't do any 
power conditioning at all and simply swap to batteries when the power goes 
out, while some will run you through the rectifier at all times. The first 
option often comes with an exciting subsecond glitch while the unit 
recognises there is no power and switches to battery (short, but long 
enough to take gear down). The other route may provide protection against 
peaks, but not against brownouts, or it may provide both. Read carefully 
and spend wisely. Not that I've ever seen anyone caught out by buying a 
cheap(ish) UPS and not getting the protection they thought they  were 
getting ...

As an aside, what are US domestic outlets rated for ? In the UK, I think 
an outlet is generally  rated for 3 kilowatts, so you can run a fairly 
extensive set of gear off a single socket so long as you don't do anything 
too daft, like endless daisy chains of four-bars ...
