Old or crowded DB boards struggle with today’s loads and Victoria Falls’ return-of-supply spikes. We rework and upgrade your board so protection devices trip correctly and daily use is simple.
First, we assess what’s there — breaker types, cable sizes, earth continuity, shared neutrals, and any inverter or generator feeds. Then we propose a clear plan: enclosure (if needed), correct breaker curves, RCDs/RCBOs, and Type 1/2 surge protection.
Nuisance tripping isn’t “normal”; it’s usually poor grouping or shared neutrals. We separate circuits, balance loads, and fit the right devices so trips point to real faults instead of constant blackouts.
With storms and grid spikes, surge protection plus proper earthing saves electronics. We install DB-level devices and advise point-of-use protection for sensitive gear like POS, TVs, and routers.
If you have a generator or inverter, we add a safe changeover/ATS and set neutral/earth arrangements correctly. Clear labelling and a simple handover mean anyone can operate the setup confidently.
We work across CBD, Chinotimba, Mkhosana, Aerodrome, and the Industrial Area. Expect tidy wiring, a labelled board, and practical advice for Victoria Falls conditions.
FAQs
How do I know my DB needs an upgrade?
Signs include frequent nuisance trips, warm/burnt breakers, mixed breaker types jammed together, or add-on wiring for inverters/generators hanging off the side. Lack of RCDs and surge protection is another clue.
RCD vs RCBO — which should I choose?
An RCD protects a group of circuits from earth leakage; an RCBO protects a single circuit from both earth leakage and over-current. RCBOs reduce whole-house outages because one fault won’t drop everything — ideal for homes, shops, and lodges.
Will surge protection really help with spikes in Vic Falls?
Yes — when paired with solid earthing. We fit Type 1/2 devices at the DB to clamp big surges when power returns, and recommend point-of-use units for sensitive equipment.
Can you integrate my inverter and generator safely?
We can. We install a compliant changeover/ATS, set neutral/earth correctly for each source, and separate backup circuits so there’s no back-feed into ZETDC. Everything is labelled with a simple switching routine.
Why does my earth leakage trip at random times?
Often shared neutrals, damp outdoor circuits, or too many mixed circuits on one RCD. We test insulation resistance, split problem circuits, and fit the right RCD/RCBO layout so trips are meaningful.
Do you do small fixes or only full board replacements?
Both. From replacing a failed RCD in Chinotimba to a full DB rebuild in Mkhosana, we match the scope to your problem and budget.
