Standby power that a working city can rely on
Germiston doesn’t stop when the grid does. The factories and plants of Wadeville and Knights run to a schedule, the offices around President Street keep trading, and homes in Primrose, Lambton and Elspark still expect the lights to come on. A standby generator is the thing that makes that possible — but only if it starts, holds the load and hands over cleanly every single time. When it doesn’t, you want it back fast and fixed properly.
Electromech repairs, services and maintains diesel and petrol generator sets across Germiston, from small home standby units to heavy three-phase sets on the factory floor. Our technicians are qualified in both the mechanical and electrical trades — the combination a generator genuinely needs — and we source spares from the original manufacturer so a repair holds.
Why Germiston trusts us
Built for an industrial town
Industrial experience
Three-phase sets, motor loads and plant switchgear are daily work for us in Wadeville, Knights and Driehoek — not unfamiliar territory.
Two trades in one
Engine and alternator, fuel system and control panel — qualified in both, so nothing gets handed off or left half-done.
Minimal downtime
Swift diagnosis, genuine spares and on-site or workshop repair to get you producing again quickly.
Maintenance that prevents
Service agreements with load testing and optional diesel fill, so failures are caught in the workshop, not on the line.
Repairs & servicing
What we look after on your generator
Sets from 5 kVA to 1500 kVA — the whole machine, not just the easy half.
Alternators & output
No output, unstable voltage, AVR and winding faults on single and three-phase alternators — the electrical side sorted properly.
Changeover & ATS
Manual and automatic transfer switches repaired and set up so the plant moves onto standby power without anyone lifting a finger.
Scheduled servicing
Planned services with a real load test, so a set stands ready for the next outage instead of failing under load.
Control panels
Controller faults, sensor and instrumentation problems, and start/stop logic that isn’t behaving as it should.
Generators & backup →Breakdown response
A dead set mid-shift is urgent. Our standby crew attends breakdowns, with our Germiston emergency electricians on hand for the wiring side.
On the factory floor
Three-phase and industrial sets are our comfort zone
The bigger the installation, the more the two trades have to work together. On a Wadeville or Knights production line, a stopped generator can idle an entire shift, and the fault might sit in the engine, the alternator, the changeover or the control logic. Because we carry both skill sets, we diagnose across all of them at once, repair on site where we can and in our workshop where we must, and get you back to full output with the least disruption.
For the electrical work we sign off to SANS regulations and can issue a Certificate of Compliance, and we’re equally at home on commercial and industrial installations more broadly.

FAQs
Generator Repairs in Germiston — frequently asked questions
Quick answers to the questions we hear most in Germiston. Search or browse below.
What size generators do you work on?
A wide range. We service and repair small standby units from around 5 kVA right up to 1500 kVA industrial sets, and we look after larger installations of 100 kVA and above for Germiston's factories and commercial sites in Wadeville, Knights and beyond.
Do you repair both diesel and petrol generators?
Yes. Our technicians are qualified electrically and mechanically, so we handle diesel and petrol sets — engine faults, starting and charging problems, alternator issues and the control and changeover wiring around them.
My generator won't start or won't take the load. Can you help?
That's a common call. Non-starts, sets that run but won't switch over, tripping on load, or a unit that only ran during the last bout of load shedding — we diagnose the fault across the engine, alternator and ATS and repair it properly.
Can you install or repair an automatic changeover (ATS)?
We can. We install, fault-find and repair automatic transfer switches and manual changeover gear so your Germiston property switches to backup cleanly and safely when the grid drops, all wired to SANS 10142.
Do you offer generator servicing and maintenance contracts?
Yes. Regular servicing — oil, filters, coolant, belts, battery and a load test — keeps a set reliable for when you actually need it. We set up preventative maintenance schedules for homes, businesses and industrial plants around Germiston.
Can you handle the electrical side as well as the engine?
That's our advantage. Because we're a full electrical contractor too, we cover the whole picture — the DB and changeover wiring, the supply integration and a Certificate of Compliance — not just the mechanical repair.
Do you service generators at factories in Wadeville and Knights?
Regularly. Industrial standby power is a big part of our work in Germiston, and we plan servicing and repairs around production so a maintenance visit doesn't cost you a shift.
