Task guide
When this may be needed
- A breaker trips even with little on the circuit.
- The breaker won't stay on after resetting.
- The breaker's switch is loose or broken.
- The breaker is warm or discoloured.
- A circuit has the wrong breaker rating for its cable.
What the team does
The technician confirms the breaker, not the circuit, is at fault by testing the circuit. The rating needed for the circuit's cable and load is checked, so the replacement protects the cable properly. With the supply isolated, the old breaker is removed, the new one fitted to the busbar and the circuit connected firmly. The circuit is tested and labelled.
Included in this price

Limits & price factors

FAQs
An MCB protects one circuit from overload and short circuits. An RCCB protects people from electric shock by tripping when current leaks to earth. Most homes need both.
No. The breaker's rating matches the cable. A bigger breaker lets the cable overheat. Find the cause of the trip instead.
Replacing breakers is electrical installation work that must be done by a licensed electrical worker.
