There are two different flavors of 220/230/240 volts. Some places have a
simple system with one wire hot and one wire grounded. Other places have
a split system where the voltage is split in half to get 110/115/120 volts
relative to ground, by adding a additional "middle" conductor that is the
grounded one.
