Edmondson Park is one of Sydney's newest growth suburbs, and most new estate homes here are specified with three phase power from the day they are built. We're Level 2 ASP electricians upgrading Edmondson Park homes from single phase to three phase power, safely and compliantly.
Three Phase Power Upgrades Built for Edmondson Park
Edmondson Park homes (2174) are increasingly outgrowing the single phase supply they were built with, a pattern that shows up locally through new estate growth corridor. Modern loads add up fast, ducted air conditioning, induction cooktops, EV chargers, pool equipment and a home office, and a single phase 60 to 100 amp service shows the strain through tripping mains, dim lights and appliances that struggle to perform.
For the handful of established or older Edmondson Park properties still on single phase, upgrading brings them in line with the estate homes around them. Load is spread evenly across three conductors instead of one, voltage stays stable, and you unlock equipment new builds take for granted, fast EV charging, ducted air conditioning and larger solar systems.
As authorised Level 2 electricians, we're certified to disconnect and reconnect directly to the Endeavour Energy network that supplies Edmondson Park, so the whole upgrade is handled by one team from quote to energised.


Why Edmondson Park Properties Are Upgrading to Three Phase
Edmondson Park sits within South-West Sydney, served by the Liverpool City Council. These are the upgrade triggers we see most often in 2174:
- New estate construction that specifies three phase from day one, prompting nearby older properties to upgrade.
- EV ownership, with fast home chargers common across this newer estate.
- Solar and battery systems sized to take advantage of a full three phase supply.
- Ducted air conditioning across larger, modern floor plans.
- Granny flats or secondary dwellings added as families settle into the area.
- Home businesses needing reliable, higher capacity power.

Reliable capacity
Handle heavy loads at the same time, ducted air conditioning, a pool pump, an EV charger and the oven, without the mains giving up.
Future-proof for EVs & solar
Gives you the headroom to add a second EV, a bigger battery or a larger solar array whenever you are ready.
Longer appliance life
Spreading the load across three conductors reduces the voltage sag that shortens the life of motors and pumps.
Lower running costs
Efficient three phase equipment and a stable supply add up to a leaner power bill over the year.
Property value
A certified three phase upgrade is a real point of difference when the property is next on the market.
Compliance peace of mind
Full Certificate of Compliance, Level 2 ASP sign off and network approved metering, every time.
Do I Need A Power Upgrade?
You should consider upgrading if you:
- Install multiple high-power appliances or industrial equipment.
- Are renovating or constructing a new building that will have increased energy requirements.
- Require adherence to the latest safety standards and electrical codes, which may mandate more robust systems.

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
Does a three phase upgrade affect my solar system?
It can improve it. A three phase supply lets a hybrid inverter export more evenly and generally performs better than a single phase system straining under a large array, worth discussing if you are planning solar or a battery in Edmondson Park.
How much does a single to three phase upgrade cost in 2174?
Costs depend on switchboard scope, mains length, point of attachment changes and Endeavour Energy network requirements. We provide a detailed fixed quote after a free on site assessment, so there are no surprises mid job.
Is a three phase upgrade disruptive to neighbours?
Most of the work happens inside your switchboard and meter box. If overhead network changes are required on your street, Endeavour Energy schedules that separately and notifies affected neighbours directly.
Do I need three phase power for an EV charger?
For a standard 7 kW home charger, no. For an 11 kW or 22 kW charger, which are becoming more common in Edmondson Park driveways and garages, yes, three phase supply is required.
Are you authorised to work on the Endeavour Energy network in Edmondson Park?
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 South-West Sydney.
