A renovation or extension is one of the most common times we get called out to Kirrawee, once the added loads make it clear the existing single phase supply is maxed out. We're the local Level 2 ASP team upgrading Kirrawee properties from single phase to three phase power, coordinated directly with Ausgrid.
Kirrawee Three Phase Power Upgrade Specialists
A renovation or extension is one of the most common times we get called out to Kirrawee (2232). Once the new kitchen, ducted air conditioning, extra bathroom and EV charger are all accounted for, the existing single phase supply is often maxed out before the fit off is even finished.
A three phase supply gives your Kirrawee 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 Ausgrid network, so your upgrade is quoted, installed and certified by the one team.
What's Driving Three Phase Upgrades in Kirrawee
Kirrawee falls under Sutherland Shire Council and sits on the Ausgrid network. Across 2232 and the surrounding streets, these are the signs we see most before a three phase upgrade:
- A granny flat or secondary dwelling on the block, which pushes total demand well past what the original single phase supply was designed for.
- Mains that trip regularly once the air conditioning, oven and another large appliance are running together.
- Lights that visibly dim across the house whenever a large appliance or the air conditioning compressor starts up.
- A home based business or tradie's setup that needs reliable three phase power for tools and equipment.
- A renovation, extension or rebuild that adds a new kitchen, extra bathroom or additional living space to the home.
- A pool or spa with a pump and heater that draws heavily on the supply, especially in summer alongside ducted air conditioning.

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 Kirrawee 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 2232?
Costs vary based on switchboard scope, mains length, point of attachment changes and Ausgrid requirements. We provide a detailed fixed quote after a free on site assessment, so there are no surprises mid job.
Will my switchboard need to be replaced?
In most cases, yes. A three phase upgrade almost always requires a new switchboard sized for three phases, along with updated safety switches and circuit protection to current AS/NZS 3000 standards.
Do I need three phase for an EV charger?
For a standard 7 kW home charger, no. For an 11 kW or 22 kW charger, which is increasingly common in Kirrawee garages, yes, three phase is required.
Are you authorised to work on the Ausgrid network in Kirrawee?
Yes. High Demand Electrical is a Level 2 ASP under Licence 397193C, authorised to disconnect, upgrade and reconnect directly to the Ausgrid network throughout the Sutherland Shire 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.
