17.3. Check of the Circuit Separation
PURPOSE OF THE TEST
The test, to be effected in case the protection is realised through separation (SELV or
PELV or electrical separation), shall check that the insulation resistance measured
according to the indications below (depending on the separation type) complies with the
limits reported in the table relative to the insulation measurements.
 INSTALLATIONPARTS TO BE CHECKED
SELV system (Safety Extra Low Voltage):
 measure the resistance between the active parts of the circuit under test
(separate) and the active parts of the other circuits.

measure the resistance between the active parts of the circuit under test
(separate) and the earth.
PELV system (Protective Extra Low Voltage):
 measure the resistance between the active parts of the circuit under test
(separate) and the active parts of the other circuits.
Electrical separation :
 measure the resistance between the active parts of the circuit under test
(separate) and the active parts of the other circuits.
 measure the resistance between the active parts of the circuit under test
(separate) and the earth.
