6. PRACTICAL EXAMPLES OF ELECTRICAL TESTS
6.1 LOW CONTINUITY MEASUREMENT
CONTINUITY MEASUREMENT ON PROTECTIVE CONDUCTORS
PURPOSE OF THE TEST
Check the continuity of: protective conductors (PE), main equalising potential
conductors (EQP), secondary equalising potential
conductors (EQS) in TT and TN-S systems.
neutral conductors having functions of protective
conductors (PEN) in TN-C system.
NOTE: This test is to be preceded by a visual check verifying the existence of yellow-
green protective and equalising potential conductors as well as compliance of
the sections used with the standards’ requirements.
INSTALLATION PARTS TO BE CHECKED.
Equalising
potential node
Connect one of the
test leads to the
protective conductor
of the FM socket
and the other to the
equalising potential
node of the earth
installation.
Connect one of the
test lead to the
external mass (in
this case the water
pipe) and the other
to the earth
installation using for
example the
protective conductor
of the closest FM
socket.
