Operation of the TEST button on RCBO
When newly fitted systems do not trip on the TEST button or using the RCD tester the problem is normally caused by an earth to
neutral fault on the circuit (PME supply).
Installers can easily check the RCBO by removing the LOAD connections on the RCBO and applying power. If the TEST button
works the fault is in the circuit.
RCBO TEST
RCBOs ARE MANUFACTURED IN ACCORDANCE WITH IEC 61009-1 AND MUST BE TESTED TO THIS SPECIFICATION USING A
CALIBRATED TEST METER.
General type
0.5IΔn RCBO will not trip
1Δn RCBO must trip within 300ms
5IΔn RCBO must trip within 40ms
What to do if a RCBO trips
1 Reset tripped RCBO to ON position
2 If RCBO trips again then disconnect all appliances connected to this circuit.
3 Switch RCBO to ON position and connect 1 appliance at a time to see which one trips the RCBO.
4 Once the faulty appliance has been identified, DO NOT USE appliance until it has been checked.
5 Switch RCBO to ON position.
