No, that's wrong. We have a hot and a neutral wire too here, and the
neutral is at earth potential, i.e. can be touched without danger. But
here in Germany the mains plug can be inserted both ways, so in a
device with a mains plug you never know which of the two mains wires
is hot. In other countries in Europe this is different, at least for
the 3-prong plugs.
