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.)
