DB board upgrades in Randburg — what we actually find
Randburg's high proportion of homes converted into offices and back rooms means the board is usually being asked to carry far more than it was sized for. We calculate the actual demand before recommending an upgrade rather than fitting the largest board available. Sub-boards feeding cottages and outbuildings without their own earth leakage are a straight COC failure and are corrected as part of the same visit.
Property stock in Randburg
Randburg's older freehold homes around Ferndale and Blairgowrie still have galvanised supply pipe in the walls, and once it starts weeping the pressure drop shows at the furthest tap first. Complexes here often share a single bulk meter, which makes one unit's internal leak everyone's problem. A high proportion of homes have been converted into offices or back rooms, each conversion adding load to a board sized for a family house.
Freehold access is direct. On bulk-metered complexes we coordinate with the managing agent, because isolating to test a single unit affects the others.

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 Randburg 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
