Hinchinbrook's 1990s family homes are being fitted with pools, EV chargers and granny flats faster than the original single phase supply can handle. We're Level 2 ASP electricians upgrading Hinchinbrook homes from single phase to three phase power, safely and compliantly.
Three Phase Power Upgrades Built for Hinchinbrook
Hinchinbrook homes (2168) are increasingly outgrowing the single phase supply they were built with, a pattern that shows up locally through family pool and granny flat growth. A single phase 60 to 100 amp service was never designed for today's mix of ducted air conditioning, induction cooktops, EV chargers and home office equipment, and the symptoms show up as tripping mains, dim lights and premature appliance wear.
Upgrading to three phase power gives a Hinchinbrook property the capacity a growing family needs. Load is spread evenly across three conductors instead of one, voltage stays stable, and you unlock equipment single phase cannot run, a pool heat pump, an EV charger, a granny flat, together.
As authorised Level 2 electricians, we're certified to disconnect and reconnect directly to the Endeavour Energy network that supplies Hinchinbrook, so the whole upgrade is handled by one team from quote to energised.


Why Hinchinbrook Properties Are Upgrading to Three Phase
Hinchinbrook sits within South-West Sydney, served by the Liverpool City Council. These are the upgrade triggers we see most often in 2168:
- Pool and spa heat pumps on established Hinchinbrook blocks.
- Granny flats and secondary dwellings for extended family.
- EV ownership, with home chargers increasingly common.
- Ducted air conditioning replacing older split systems.
- Renovations and extensions adding extra living space.
- Solar and battery upgrades that perform better on three phase.

Reliable capacity
Keep voltage steady across the whole property even when air conditioning, cooking and charging are all drawing power at once.
Future-proof for EVs & solar
Keeps the property ahead of the curve as EV charging and home battery systems become the norm rather than the exception.
Longer appliance life
Steadier voltage across the property means less wear on pumps, motors and sensitive electronics.
Lower running costs
Three phase motors and HVAC systems run more efficiently, which helps keep running costs down.
Property value
Buyers increasingly ask about supply capacity, and three phase power is an easy tick on the building report.
Compliance peace of mind
Every upgrade leaves you with a Certificate of Compliance, Level 2 ASP sign off and properly approved metering on file.
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
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.
How much does a single to three phase upgrade cost in 2168?
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.
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 give you advance notice so you can plan around fridges, work from home setups and any pool or aquarium equipment.
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 Hinchinbrook.
Are you authorised to work on the Endeavour Energy network in Hinchinbrook?
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.
