Plenty of Bonnyrigg homes are still running on the same single phase supply they were built with decades ago, long before ducted air conditioning, EV chargers and induction cooktops became the norm. We're the local Level 2 ASP team upgrading Bonnyrigg properties from single phase to three phase power, coordinated directly with Endeavour Energy.
Bonnyrigg Three Phase Power Upgrade Specialists
Many Bonnyrigg homes (2177) were built with a single phase 60 to 80 amp supply, which was plenty for the appliances of the time but not for a household running ducted air conditioning, an induction cooktop, an EV charger and a home office all at once. When that happens, the usual signs are mains that trip under load, lights that dim when the air conditioning starts, and appliances that seem to run slower or wear out faster than they should.
A three phase supply gives your Bonnyrigg property real headroom, spreading demand across three conductors so voltage stays stable and heavy equipment like EV chargers, ducted systems and workshop machinery can all run without tripping the mains. We hold Level 2 ASP authorisation to work directly on the Endeavour Energy network, so your upgrade is quoted, installed and certified by the one team.
What's Driving Three Phase Upgrades in Bonnyrigg
Bonnyrigg falls under Fairfield City Council and sits on the Endeavour Energy network. Across 2177 and the surrounding streets, these are the signs we see most before a three phase upgrade:
- A renovation, extension or rebuild that adds a new kitchen, extra bathroom or additional living space to the home.
- Heavy appliance loads, ducted reverse cycle air conditioning, spa heaters, instant hot water and EV charging all running at the same time.
- Solar and battery upgrades, since modern hybrid inverters perform better, export more and last longer on a three phase supply.
- Mains that trip regularly once the air conditioning, oven and another large appliance are running together.
- An older home still wired for the original 60 to 80 amp single phase supply it was built with, long before modern appliance loads existed.
- A pool or spa with a pump and heater that draws heavily on the supply, especially in summer alongside ducted air conditioning.

Do I Need A Power Upgrade?

What is a Three Phase Power Upgrade?
Single phase power uses one live wire and typically provides up to 240 volts, adequate for light loads but not optimal for heavier consumption without risking system overload and inefficiency. In contrast, a three phase power system incorporates three alternating currents, equally spaced in phase angle, providing up to 415 volts. This configuration allows for a more consistent delivery of power, as the total power delivered never drops to zero, a distinct advantage particularly in industrial settings or in homes with high energy demands.

FAQs
What are the signs my Bonnyrigg home needs three phase power?
The most common signs are mains that trip once several large appliances run together, lights that dim when the air conditioning or oven starts, and slow recovery on hot water or ducted systems. If that sounds familiar, it's worth getting a free assessment.
How much does a single to three phase upgrade cost in 2177?
Costs vary based on switchboard scope, mains length, point of attachment changes and Endeavour Energy requirements. We provide a detailed fixed quote after a free on site assessment, so there are no surprises mid job.
Will I lose power during the upgrade?
Yes, briefly. We coordinate the changeover to minimise disruption, typically a few hours on the day of energisation. We'll give you advance notice so you can plan around fridges, work from home setups and pool equipment.
Does a three phase upgrade help with solar or battery?
Yes. Larger hybrid inverters and battery systems generally perform better and export more on a three phase supply, so it's worth planning the upgrade at the same time as a solar or battery installation.
Are you authorised to work on the Endeavour Energy network in Bonnyrigg?
Yes. High Demand Electrical is a Level 2 ASP under Licence 397193C, authorised to disconnect, upgrade and reconnect directly to the Endeavour Energy network throughout the South West Sydney area.

"Chris was the professional, punctual and his services are exceptional. Chris re-wired the entire property, chased the electrical work in the bathroom and kitchen areas, left a clean and tidy environment and his open communication and dialogue was a welcomed experience.
When he quoted an arrival time, he was there. He talked me through what he was doing, and provided feedback/suggestions on how to tackle any issues. I felt part of the process, as opposed to being another Customer.
