An MCB (miniature circuit breaker) is the switch in your distribution board that cuts power to a circuit when it overloads or short circuits. It protects the cable in the wall from overheating, and protects you from the damage a fault can cause. Each circuit needs a breaker rated for the cable it protects and the load it carries.
We fit or replace MCBs so that lighting, sockets and heavy appliances each sit on a suitable rating, and we check that the breaker matches the cable behind it. A breaker rated too high will not trip before the wiring overheats, and one rated too low will trip all the time.
New breakers are connected, labelled and tested before we leave.
Problems we solve
- Breakers that trip repeatedly
- An old board with missing or mismatched breakers
- Heavy appliances added to a circuit not meant for them
- A breaker that feels hot or will not stay on
- No clear labels showing what each breaker controls
- No protection on a newly added circuit
Our process
- 1
Check the circuit
We note the cable size and the load before choosing a rating.
- 2
Select the breaker
The MCB rating is matched to the cable and the appliances on that circuit.
- 3
Install and connect
The breaker is fitted in the board with tight, correct connections.
- 4
Label and test
Each breaker is labelled and tested.
Benefits
- Wiring protected from overload
