Safe Isolation
The supply is isolated before any work on the board, and we confirm it is dead before touching connections.
Distribution Board (DB) Repair in Dubai
Tripping breakers and faulty distribution boards diagnosed and repaired
In Brief
Distribution board (DB) repair is diagnosing and fixing faults in the panel that feeds all the circuits in your property: breakers that trip, switches that will not stay on, loose or overheated connections, and circuits that are overloaded. The cause is traced first, then the faulty part is repaired or replaced.
The distribution board, often called the DB or fuse box, takes power in and shares it between the lights, sockets, AC and other circuits, each protected by its own breaker. When a breaker keeps tripping, it is doing its job: something on that circuit is drawing too much current, leaking current to earth or has a fault. Resetting it again and again, or replacing it with a larger one, hides the problem and can be dangerous.
We isolate the supply before working on the board, then trace the cause by testing the circuit, disconnecting loads one at a time and checking connections for looseness or heat damage. The repair might be a faulty breaker, an overloaded circuit that needs splitting, a loose connection or a damaged appliance on the circuit. Work that affects the incoming supply follows the rules set by the building and the authorities.

When You Need This
Signs You May Need Distribution Board (DB) Repair
- A breaker trips repeatedly or will not reset
- Part of the property loses power while the rest still works
- A burning smell, buzzing or warm spot comes from the board
- Lights flicker or dim when a large appliance such as the AC starts
- The board is old, crowded or has unlabelled circuits
What We Do
What Distribution Board (DB) Repair Covers
Fault Tracing
We test each circuit and disconnect loads one at a time to find what is causing the breaker to trip.
Breaker and RCD Replacement
Faulty circuit breakers and earth-leakage protection devices are replaced with ones suited to the circuit.
Connection Checks
Loose, burnt or overheated connections are tightened or replaced, since heat damage is a common cause of faults.
Overloaded Circuits
Where a circuit is carrying too much, we advise on splitting it or adding a circuit so the load is shared properly.
Labelling and Tidy-Up
Circuits are labelled so you know what each breaker controls, and the board is left tidy and tested.
Our Process
How It Works
- 1
Describe What Trips
Tell us which breaker trips, when it happens, and what was running at the time. Photos of the board help.
- 2
Isolate and Inspect
We isolate the supply and inspect the board for damage, loose connections and unsuitable parts.
- 3
Trace and Repair
We find the faulty circuit or part, explain what is wrong and confirm the price before repairing it.
- 4
Test and Label
Circuits are tested, labelled and switched back on, and we show you what each breaker does.
Good to Know
What Affects Time and Cost
Every property is different, so we confirm the price before any work starts. These are the things that most often change the time and cost.
- Whether the fault is in the board, a circuit or an appliance
- The age and condition of the board and its parts
- Whether circuits need to be added or split
- Whether the work affects the incoming supply or the building's approvals
- How accessible the board and wiring are
FAQ
Distribution Board (DB) Repair Questions
It means a circuit is overloaded, has a short, or is leaking current to earth. Common causes are a faulty appliance, damaged wiring or too many items on one circuit. We trace the cause rather than just resetting it.
No. A breaker protects the wiring behind it. Fitting a larger one can let the wire overheat. We find the cause and, if needed, split or upgrade the circuit.
Switch off at the main if it is safe to do so and call us. Do not keep using the circuit. See emergency maintenance for urgent faults.
Yes, if the board and supply can take it. We check the load first and advise on what is needed.
Yes. Clear labelling helps you and any future electrician know what each breaker controls.
