− correct positioning of the conductors;
− adequate space between the underside of the base and the surface on which the base is
mounted or between the sides of the base and the enclosure (cover or box) so that, after
installation of the socket-outlet, the insulation of the conductors is not necessarily pressed
against live parts of different polarity.
NOTE This requirement does not imply that the metal parts of the terminal are necessarily protected by insulating barriers or
insulating shoulders, to avoid contact due to incorrect installation of the terminal metal parts, with the insulation of
For surface type socket-outlets to be mounted on a mounting plate, a wiring channel may be
needed to comply with this requirement.
