FAQs
What is the function of an RCBO?
An RCBO (Residual Current Breaker with Overcurrent protection) combines the functions of an MCB (Miniature Circuit Breaker) and an RCD (Residual Current Device), protecting against both overcurrents and earth faults.
Who should install the Axiom Mini RCBO?
Installation must be performed by a qualified electrician to ensure safety and compliance with electrical regulations.
How often should I test the RCBO?
Test the RCBO at least every six months using the test button to ensure it is functioning correctly.
What does the 20A rating mean?
The 20A rating indicates the maximum current the RCBO can safely handle continuously. If the current exceeds 20A, the device will trip and cut off the power.
What does the 30mA sensitivity mean?
The 30mA sensitivity refers to the earth leakage current threshold. If an earth fault current of 30mA or more is detected, the RCBO will trip.
Can the Axiom Mini RCBO be used outdoors?
The Axiom Mini RCBO has an IP20 rating and is generally not suitable for outdoor use. It should be installed in a protected indoor environment.
What is the warranty period for the Axiom Mini RCBO?
The Axiom Mini RCBO comes with a 1-year warranty.
What should I do if the RCBO trips and I can't find a fault?
If the RCBO trips repeatedly and no obvious fault can be found, consult a qualified electrician to inspect the circuit and the RCBO itself.
Troubleshooting
RCBO trips frequently.
Check the connected circuits for earth faults or overloads. Inspect appliances and wiring for damage. If the issue persists, the RCBO may need to be replaced.
RCBO does not trip when the test button is pressed.
The RCBO may be faulty and should be replaced. Contact a qualified electrician to inspect the device and the associated wiring.
RCBO trips immediately after being reset.
There is likely a fault in the connected circuit. Isolate the circuit, inspect wiring and appliances, and repair or replace any damaged components. Ensure the fault is resolved before resetting the RCBO.
The device feels warm to the touch.
Check for excessive load on the circuit, ensure proper ventilation, and consult an electrician to assess for potential issues with the wiring or device.
