Expert DB Board Upgrades in Centurion
Your distribution board is the control centre of your entire electrical system. An outdated, overloaded, or faulty DB board is one of the most common causes of electrical fires in South African homes. Electrician Centurion upgrades, replaces, and repairs distribution boards for homes and businesses across Centurion — safely, correctly, and with a Certificate of Compliance on completion.
We replace old rewirable fuse boards with modern MCB (miniature circuit breaker) boards, add RCCB earth leakage protection, install surge protection, and correctly size each circuit breaker for the load it protects. The result is a safer, code-compliant electrical system with proper protection for your home and appliances.
Why Choose Electrician Centurion for DB Boards
Modern MCB & RCCB Protection
We replace outdated fuse wire boards with modern MCB circuit breakers and RCCB earth leakage protection — providing proper fault protection that fuse wire cannot offer.
Surge Protection Installation
We install Type 1 and Type 2 surge protection devices to protect your home and appliances from lightning and grid voltage surges — essential in South Africa.
Correctly Sized Circuits
Every circuit breaker is sized correctly for the cable and load it protects. Oversized breakers are a major fire risk — we get this right.
COC Issued on Completion
Every DB board upgrade includes a valid Certificate of Compliance — required for your insurance and essential if you're selling your property.
Signs Your DB Board Needs Attention
-
Frequently Tripping Breakers Breakers that trip regularly indicate overloaded circuits, a faulty appliance, or an undersized board that can't cope with your home's electrical demand.
-
Old Fuse Wire Board If your DB board uses fuse wire instead of circuit breakers, it provides almost no protection against electrical faults and must be replaced immediately.
-
Burning Smell or Scorch Marks Any smell of burning plastic or visible scorch marks on or around your DB board is an emergency — turn off the mains and call us immediately.
-
Flickering Lights Whole-house flickering or lights dimming when appliances start can indicate a loose connection or faulty main breaker inside the DB board.
-
No Earth Leakage Protection Older boards often lack RCCB (earth leakage) protection — a critical safety device that disconnects power instantly if current leaks to earth, preventing electrocution.

Frequently Asked Questions — DB Boards
How do I know if my DB board needs replacing?
Key signs include: frequent tripping, an old fuse wire board (not circuit breakers), burning smells, scorch marks, or a board that's more than 20 years old. Call us for a free assessment — 078 912 0847.
How long does a DB board replacement take?
A standard residential DB board upgrade typically takes 3 to 5 hours. You'll have power off only during the replacement itself — we work as quickly as possible to minimise disruption.
What is an RCCB and do I need one?
An RCCB (Residual Current Circuit Breaker) is an earth leakage protection device that cuts power in milliseconds if it detects current leaking to earth — preventing electrocution. SANS requires RCCB protection in all South African homes.
Can you add more circuits to my existing DB board?
Yes — if your board has capacity, we can add new circuits for additional rooms, appliances, or solar systems. If the board is full or outdated, we'll recommend an upgrade or sub-board installation.
Is surge protection worth installing?
Yes — especially in South Africa. Lightning strikes and Eskom grid switching surges can destroy appliances and electronics instantly. A properly installed Type 2 surge protector pays for itself the first time your area gets a lightning storm.
