How do I know my board needs upgrading?

Open the cover. Re-wireable fuses, or no unit with a test button on it, both mean an upgrade is due regardless of anything else. No spare ways, overcrowded terminals, or any buzzing or discolouration are the other signals — and buzzing means call today, not book next week.

Do I need this before installing solar?

Almost always. Solar and battery systems need essential-loads separation and proper isolation, and an old board simply has nowhere to put it. Doing the board first also means the solar installation can be certified rather than held up while the board is dealt with mid-project.

Will I get an Electrical COC?

Yes, issued in the registered person's own name with their registration number on it. That certificate covers the installation as it stands on the day, which is why it is worth doing the board and any other outstanding electrical work as one exercise rather than in pieces.

DB board upgrades in Rosebank — what we actually find

In a Rosebank tenancy the board upgrade has to start with a boundary. Units are metered off a landlord's main, so the certificate must state clearly where the tenant's installation begins, and we define that in writing. Successive shopfits also leave abandoned circuits live behind ceilings, and those are traced out and made dead as part of the work rather than left for the next refit.

Property stock in Rosebank

Rosebank is mostly apartments and light-commercial buildings, so access is usually the constraint rather than the plumbing or wiring itself. Stack pressure in the taller blocks means a failed non-return valve on one floor pushes water back into the units below. Commercial tenancies are metered per unit off a landlord's main, and years of shopfitting have left abandoned circuits live behind ceilings.

Booking the service lift and the building's plumber sign-in usually takes longer than the repair. We arrange both with the managing agent before the visit.

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 Rosebank 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
