DB board upgrades in Centurion — what we actually find
Before quoting a Centurion board we establish which side of the bulk meter the fault sits on, because on the estates a problem can belong to estate reticulation rather than to your installation. Borehole pumps and irrigation controllers are the usual source of nuisance earth leakage here, particularly after wet weather, so we isolate them individually rather than simply replacing the earth-leakage unit.
Property stock in Centurion
Centurion sits high, and the estates around Eldoraigne and Highveld often run boosted pressure to push water to the top of the stand. That pressure is what splits older poly fittings under driveways and shortens the life of geyser elements and mixer cartridges. On the smallholdings at the edge of Centurion, borehole water frequently runs alongside the municipal supply, and the two need a proper non-return arrangement to remain legal.
Many Centurion estates run their own reticulation behind a bulk meter, so faults can sit on estate infrastructure rather than the municipal side. We establish which before anyone is billed, and clear estate access in advance.
Faults that cluster in Centurion
- Boosted estate pressure splitting older poly fittings under driveways
- Borehole and municipal supplies joined without a compliant non-return arrangement
- Borehole pumps and irrigation controllers causing nuisance earth leakage after wet weather
- Faults sitting on estate reticulation behind the bulk meter rather than the municipal supply
How DB board upgrades works
A distribution board needs upgrading if it is more than about twenty-five years old, still uses re-wireable fuses, has no earth leakage protection, or predates current SANS 10142 layout requirements. It is also effectively a prerequisite for solar, an EV charger or any significant renovation, because the new work has to be certified and an old board will not support it. A board that buzzes or smells hot is not a scheduling matter — that is how board fires start.
- Full board replacement to current SANS 10142 requirements
- Earth leakage protection where none is fitted, and correct circuit separation
- Surge arrester installation, which matters on the Highveld more than most places
- Load surveys before adding solar, an EV charger or renovation circuits
- Electrical COC issued in the registered person's own name on completion
Our process on a Centurion call-out
- 1Inspect the existing board, its protection devices and the circuit layout
- 2Measure actual load per circuit rather than assuming the original design still fits
- 3Quote the board, protection, surge arrester and certification as itemised work
- 4Replace and re-terminate, torque-checking every connection
- 5Test each circuit and issue the Electrical COC
