RCBO Replacement in Singapore
RCBO replacement starts from $150 at SG QuickFix. An RCBO combines an MCB and earth-leakage protection on one circuit, so a faulty appliance trips only its own circuit instead of the whole home. A faulty RCBO is replaced, or MCBs are upgraded to RCBOs, in about 30 to 60 minutes per breaker.

Task guide
When this may be needed
- An RCBO trips with nothing on its circuit.
- The RCBO's test button doesn't trip it.
- One faulty appliance trips the whole home's RCCB.
- You want the water heater or outdoor circuit on its own protection.
- The RCBO is warm or damaged.
What the team does
The technician tests the circuit and the RCBO to confirm where the fault is. The correct rating and sensitivity for the circuit are chosen. With the supply isolated, the old breaker is removed, the RCBO fitted and connected, including its neutral, and the circuit tested. The RCBO is test-tripped and labelled.

Limits & price factors
Faults on the circuit itself, and boards without space or a compatible busbar for RCBOs, are priced separately.
The price starts from $150 per RCBO. Upgrading several circuits, and older boards needing compatible parts, change the total.
FAQs
A breaker that gives one circuit both overload protection and earth-leakage protection, so a fault on that circuit trips only that circuit.
With a single RCCB, one faulty appliance can switch off the whole home. RCBOs limit the trip to the faulty circuit.
Replacing breakers is electrical installation work that must be done by a licensed electrical worker.
