Three Phase Installations

We treat three phase installations as an engineering job rather than a quick fix. Our technicians assess the whole system before recommending anything, because the fault you can see is very often a symptom of something upstream that will simply come back if it is not addressed properly the first time.

Three-phase supply is needed for large machinery, big air conditioning plant, industrial ovens, lifts and heavy workshop equipment, and it balances heavy loads far better than single phase.

We handle the application and liaison with the supply authority, install three-phase distribution boards, balance loads across phases, and connect and commission three-phase equipment correctly with phase rotation verified.

Why three phase installations matters

Load shedding, surges and Gauteng’s summer storm season are hard on both air conditioning and electrical infrastructure. Correct three phase installations builds in the protection and headroom needed to survive that environment instead of failing on the first hot Saturday of the season.

What’s included

Supply upgrade applications and liaison
Three-phase distribution board installation
Load balancing across phases
Phase rotation verification on machinery
Compliance certification

Warning signs we look for on three phase installations

A burning smell near the board, a plug point or a light fitting
Extension leads permanently in use because there are too few points
Lights dimming or flickering when large appliances start
Earth leakage tripping and needing to be reset regularly
No valid Certificate of Compliance for the property
Warm, discoloured or buzzing switches, sockets or DB board

How we handle three phase installations

1. Free assessment and written quote

We attend site, inspect what is actually there, and quote three phase installations 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 three phase installations 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 three phase installations

Anyone quoting three phase installations 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

Every job carries a written workmanship guarantee on top of the manufacturer’s warranty on parts and equipment.

Recent project

A server and comms room in Randjesfontein needed three phase installations 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.

Three Phase Installations FAQs

How do I know if I need three-phase power?

If your equipment nameplate specifies 400V three-phase, or your single-phase supply is at capacity, you need it. We assess and advise.

How much does three phase installations cost in Gauteng?

How quickly can you attend?

We aim for same-day or next-day attendance across Gauteng for three phase installations, 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. If something we installed fails within the guarantee period we come back and make it right — no argument, no callout fee.
