Isn't 208V usually provided as a connection across two phases of a 3 phase circuit? In that case, you get 120V by going between one phase and neutral (no transformer required).

Indeed it is. If you want to see it yourself, measure the voltage between "hots" on different circuits. I see 208-212V depending on the legs (they aren't evenly loaded.) This is easier to do in a data center, but with a long extention cord it can be done with the office. :-) (of course, having the building wiring diagram(s) makes for a short hunt.) --Ricky
