"The standard U.S. household wiring design has two 120 volt "hot" wires
and
a neutral which is at ground potential. The two 120 volt wires are
obtained
by grounding the centertap of the transformer supplying the house so that
when one hot wire is swinging positive with respect to ground, the other
is
swinging negative. This versatile design allows the use of either hot wire
to supply the standard 120 volt household circuits. For higher power
applications like clothes dryers, electric ranges, air conditioners, etc.
,
both hot wires can be used to produce a 240 volt circuit."
