Old or crowded DB boards struggle with today’s loads and Kwekwe’s return-of-supply spikes. We rebuild and tidy boards so protection devices trip correctly and everyday use is simple. Nothing fancy — just safe, reliable basics done well.
We start with a full check: breaker types, cable sizes, earth continuity, shared neutrals, and any inverter/generator tie-ins. Then we propose a clear plan with the right breaker curves, RCDs/RCBOs, and Type 1/2 surge protection.
Frequent nuisance tripping usually means poor circuit grouping or shared neutrals. We separate and balance circuits so trips point to real faults, not random blackouts.
Kwekwe storms and grid returns can hit electronics hard. Proper earthing plus DB-level surge protection protects fridges, POS, routers, TVs, and inverters.
Have backup power? 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, Mbizo, Chicago, Fitchlea, Goldridge, Msasa Park, Torwood, Amaveni, and Redcliff. Expect a neat board, labelled circuits, and fewer electrical headaches.
FAQs
How do I know my DB board needs an upgrade?
Warm/burnt breakers, mixed brands piled together, hanging add-on wiring, frequent trips, or no RCD/surge devices. Many older boards in Kwekwe weren’t built for today’s loads — testing confirms what to change.
RCD vs RCBO — which should I choose?
RCDs protect a group of circuits from earth leakage; RCBOs protect a single circuit from leakage and over-current. RCBOs reduce whole-house outages and make faults easier to find.
Will surge protection really help with Kwekwe spikes?
Yes — when paired with solid earthing. We fit Type 1/2 SPDs at the DB to clamp big surges when power returns and suggest point-of-use units for sensitive gear.
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 Mbizo to a full DB rebuild in Goldridge, we size the work to your installation and budget.
