PRACTICAL REPORTS FOR ELECTRICAL TESTS
11.1.
LOWΩ: CONTINUITY MEASUREMENT ON PROTECTIVE CONDUCTORS
PURPOSE OF THE TEST
Check the continuity of:
a) Protective conductors (PE), main equalizing potential conductors (EQP), secondary
equalizing potential conductors (EQS) in TT and TN-S systems.
b) 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 equalizing potential conductors as well as compliance of the
sections used with the standards' requirements.
INSTALLATION PARTS TO BE CHECKED
Examples for continuity measurement on conductors
Connect one of the
test leads to the
protective
conductor
of
the
FM socket and the
other
to
the
equalizing potential
node of the earth
installation.
Connect one of the
test leads 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.
