The protective earthing consists of a
series of contrivances, which ensure
the same earth potential in the electri-
cal earths, thus preventing the same
earths from being tensioned.
The earthing has the aim to ensure that
the earths of the household appliances
have the same potential of the earth.
Earthing also makes the automatic
intervention of the residual current de-
vice easier. Protection earthing invol-
ves not only the electrical system, but
also all the other systems and metallic
parts of the building, including piping,
beams, heating system and so on, so
that the whole building turns out to be
under safety conditions, also in case a
lightning should hit the building.
Before proceeding with the ope-
rations, see "General safety info".
The appliance must be included
in an "Equipotential" system,
