I'm thinking of standard 3 phase AC systems where each pahse is 120 degrees from the next one, such as:

http://www.tpub.com/content/doe/h1011v3/css/h1011v3_85.htm
and there are usually 2 phases coming into a home.
BTW, voltages have increased over the years, up from 110 and 117 to 120. That's one reason why older tube equipment must be carefully checked to make sure the capacitor voltages are not exceeded when used with 120 volt power as opposed to yesterdays 110 volt power.
A Dogpile search turned up these references.
