Generator Changeovers

Generator Changeovers is one of the jobs our teams are called out for most often across Gauteng. Over 15 years we have refined the process down to something predictable: an honest assessment, a written price before anyone picks up a tool, and a technician who leaves the site cleaner than they found it.

A changeover switch is what stops your generator from back-feeding into the municipal grid, which is both illegal and lethal to line workers. It also protects your generator from being destroyed when the grid returns.

We install manual changeover switches and fully automatic transfer switches with mains-failure sensing, timed start, load transfer and automatic return to mains, and we can segregate an essential-loads board so the generator only carries what it can handle.

Why generator changeovers matters

Safety is the part clients rarely see. Correct cable sizing, protection, earthing and mounting on generator changeovers is what keeps a small fault a small fault. It is also the difference between compliant work and work that will fail an inspection at the worst possible moment.

What’s included

Manual and automatic transfer switches
Essential-loads sub-board segregation
Mains-failure sensing and auto-return
Correct earthing and neutral arrangements

A burning smell near the board, a plug point or a light fitting

How we handle generator changeovers

1. Free assessment and written quote

We attend site, inspect what is actually there, and quote generator changeovers in writing with the parts, labour and any compliance work itemised. No deposit is required to get a price.

2. Scheduling that suits you

Once you approve the quote we book a slot — including after-hours and weekend work where a business cannot afford downtime — and confirm the arrival window by phone or WhatsApp the day before.

3. The work itself

A qualified technician carries out the generator changeovers to SANS standards using correctly rated materials. Drop sheets go down, the area is protected, and anything unexpected is raised with you before extra cost is incurred.

4. Testing, handover and paperwork

We test the completed work under load, walk you through what was done, and issue your invoice, warranty details and — where the job requires it — a Certificate of Compliance.

What affects the price of generator changeovers

Anyone quoting generator changeovers sight-unseen is guessing. These are the factors that genuinely move the number on our quotations:

Cable length, routing and whether chasing into walls is required
Single-phase versus three-phase supply and the rating of the circuit
Condition of the existing DB board and whether an upgrade is needed
Quality and rating of the protective devices and fittings specified
Whether a Certificate of Compliance forms part of the scope
Access, working at height, and whether the site must stay live

Our guarantee

If something we installed fails within the guarantee period we come back and make it right — no argument, no callout fee.

Recent project

A family home in Carlswald needed generator changeovers handled properly after a poor previous experience. We assessed the site, quoted in writing, completed the work to SANS standards and handed over full documentation. Read the full Generator Changeovers for a family home in Carlswald case study.

Generator Changeovers FAQs

Can I plug a generator straight into a wall socket?

No. Back-feeding is illegal and extremely dangerous. A changeover switch is the only compliant method.

How much does generator changeovers cost in Gauteng?

There is no single price — generator changeovers is quoted on scope. The assessment is free and the quotation is itemised, so you see the parts, the labour and any compliance work separately before you commit. Call 060 959 2231 and we will give you a realistic range over the phone, then confirm it on site.

How quickly can you attend?

We aim for same-day or next-day attendance across Gauteng for generator changeovers, and we run emergency call-outs after hours, over weekends and on public holidays. Booked installations are usually scheduled within a few working days.

Are your technicians qualified and insured?

Yes. Our teams are qualified, insured and, on the electrical side, registered to issue Certificates of Compliance. We only fit components we are prepared to stand behind, which is why our return-to-site rate stays in the low single digits.

Do you cover my area?

We cover the whole of Gauteng — Johannesburg, Pretoria, Centurion, Midrand, the East Rand, the West Rand and the Vaal — including estates and complexes where access has to be arranged with the HOA in advance.
