When newly fitted systems do not trip on the TEST button or using the MFT the problem is
normally caused by an earth to neutral fault on the circuit (PME supply).
Installers can easily check the AFDD/RCBO by removing the LOAD connections on the device
and applying power. If the TEST button works the fault is in the circuit.
Combined AFDD/RCBO ARE MANUFACTURED IN ACCORDANCE WITH
IEC 61009-1
AND
MUST BE TESTED TO THIS SPECIFICATION USING A CALIBRATED TEST METER.
