believe you are correct; AC power in Europe is generally derived from
3-phase where 230VAC is the voltage from Line to Neutral. In most
locations the neutral is at earth ground potential but not everywhere.
In some areas the neutral is floating (so I have been told).
It isn't floating but is earthed through an 'impedance'. I didn't find
any information on the nature and magnitude of this impedance. The
technique is used in places where the ground conductivity is much too
high to use the ground as a 'protective conductor'.

Instead of saying that the government is doing too little, too late or too
much, too early, say they've got is exactly right, thus throwing them into
total confusion.
