The plug is a NEMA 5-15.  The wiring of the power distribution box
expects 110 on each of the hot and `neutral'.  So it should look like
this:

	          110VAC--- |   | ---110VAC
			
			      O ---GND

						in the USA, with the
110's 180 degrees out of phase.  220VAC single phase is what they have in
Europe.  We ship a different plug to Europe, too.
