If your lights flicker, breakers feel too hot, or the “earth-leakage” keeps tripping, it’s a sign your DB board needs attention. Many Harare homes and businesses still run on old, crowded boards that were never designed for today’s loads, inverters, and sensitive electronics.
We upgrade, reorganise, and label your DB so it’s safe, neat, and easy to understand. That includes modern RCBO/RCD protection (earth-leakage), correct breaker sizes, clean wiring, and clear circuit labels for plugs, lights, geyser, pump, gate/garage, and inverter circuits.
Surge events happen — especially with load-shedding and grid return. We add proper surge protection (SPD) so fridges, TVs, routers, POS, computers, and inverter gear aren’t sacrificed every time power snaps back or a storm rolls through.
If you’re adding an inverter, generator, or solar, your DB must be configured correctly. We separate critical/essential loads, install compliant changeover or isolators, and make sure earthing and bonding are solid so everything plays nicely together.
Our approach is practical and tidy: replace brittle breakers, fit DIN rails correctly, remove “spaghetti” joints, install a modern enclosure if needed, and test everything with proper instruments. You’ll get a safer board and a simple handover showing what’s what.
We work across Harare — Borrowdale, Mount Pleasant, Avondale, Highlands, Greendale, Marlborough, Westgate, Mabelreign, Chisipite, CBD and surrounds — with fast response and a neat finish you can show your insurance or landlord.
FAQs
1) What’s the difference between an RCD and “earth-leakage”?
They’re the same idea. An RCD (Residual Current Device), often called earth-leakage, trips when it detects unsafe leakage to earth — protecting people from shocks. We also use RCBOs (RCD + breaker in one) for targeted protection per circuit.
2) Do I really need surge protection (SPD)?
Yes, if you value your electronics. SPDs clamp voltage spikes caused by load-shedding return, generator switching, or lightning nearby. We typically install main-board SPD protection and, where needed, point-of-use protection for sensitive gear.
3) My earth-leakage trips randomly — is it faulty?
Not always. Nuisance tripping can be caused by damp outdoor circuits, old appliances, pooled leakage across many devices, or incorrect neutral/earth connections. We test insulation resistance and circuits one by one, then fix the true cause before replacing parts.
4) Can you prepare my DB for an inverter/solar/generator?
Absolutely. We separate essential circuits, fit correct isolators/breakers, add neutral switching where required, verify earthing/bonding, and label changeover positions. The goal is smooth switching without back-feeding ZETDC or cooking your inverter.
5) How long does a DB upgrade take?
Most residential boards are done same-day. Larger homes, shops, or DBs with generator/solar integration may take longer. We minimise downtime, keep key circuits live where possible, and always test before sign-off.
6) Will you provide labels and documentation?
Yes. We label every circuit and provide a simple diagram or photo set after the upgrade. That helps with future maintenance, insurance, and quick fault-finding
