Which is a very good thing because Norway has no
neutral wire. :)
(Two phases, 220V p-p)
However, in my experience you cannot treat either phase to ground as
110V a la North American practice. Quite aside from there being no
neutral wire and thus this meaning carrying current over the ground
wire, I've seen the voltages to ground rather grossly unbalanced (like
the voltage from one side to ground being about twice the that for the
other side - 73 and 147 volts, for an exact 220V). I don't know
whether this was just a faulty installation, but it happens.
