16. PRACTICAL REPORTS FOR ELECTRICAL TESTS

16.1. Continuity Test 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 equalizing potential conductors as well as compliance of

the sections used with the standards’ requirements.

INSTALLATION PARTS TO BE CHECKED

AMPROBE

Examples for continuity measurement on conductors

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.

Connect one of the

test lead to the

protective

conductor of the

FM socket and the

other to the

equalizing potential

node of the earth

installation.
