Pool pumps, ducted air con, EV chargers, granny flats and workshops all draw more than a single phase service was built for. We're Level 2 ASP electricians upgrading Seven Hills homes from single phase to three phase power, safely and fully compliant with AS/NZS 3000.
Three Phase Power Upgrades for Seven Hills Homes
Seven Hills (2147) is a mix of older homes and light industrial premises. Whatever the era of your home, the story is often the same: the electrical service was sized for the appliances of the day, and modern living has moved well past that. On a single phase 80 to 100 amp supply, heavy loads show up as tripping mains, dimming lights, sluggish appliances and motors that wear out faster than they should.
A three phase upgrade spreads that load evenly across three conductors instead of one. Voltage stays stable under heavy draw, and you open the door to equipment a single phase service can't run at all, three phase EV chargers, larger pool heat pumps, workshop machinery and bigger reverse cycle systems among them.
As authorised Level 2 electricians, we're certified to disconnect and reconnect directly to the Endeavour Energy network that supplies Seven Hills, so the whole job, mains, switchboard, metering and certification, is handled by one team from quote to energised.
Why Seven Hills Properties Are Upgrading to Three Phase
Seven Hills sits within Western Sydney, in the Blacktown City Council area. Here are the upgrade triggers we see most often on 2147 jobs:
- An older single phase service that was never designed for today's appliance loads.
- A home workshop, shed or small business running three phase tools, welders or compressors.
- An 11 kW or 22 kW EV charger, which needs three phase supply to run at full speed.
- Instant or continuous flow hot water systems.
- Solar and battery upgrades, since modern hybrid inverters perform better on a three phase service.
- Frequent nuisance trips on the main switch when several appliances run at once.

Future-proof for EVs & solar
Lays the groundwork for a 22 kW EV charger and a larger solar or battery system, both increasingly common around 2147.
Longer appliance life
Balanced load across three conductors reduces strain on motors, compressors and electronics throughout the house.
Lower running costs
Three phase motors and HVAC systems run more efficiently, which helps keep standing losses and running costs down.
Property value
Three phase supply is a genuine selling point for Seven Hills properties, and buyers researching an upgrade path will notice it's already done.
Compliance peace of mind
A full Certificate of Compliance, Level 2 ASP sign off and Endeavour Energy approved metering, so the paperwork is sorted along with the power.
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
How long does a three phase upgrade in Seven Hills usually take?
Most Seven Hills residential upgrades are completed in 2 to 5 working days once approved. Endeavour Energy network coordination can add 1 to 3 weeks depending on whether overhead or underground works are needed on your street.
Will I lose power during the upgrade?
Yes, briefly. We coordinate the changeover to keep disruption to a minimum, usually 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.
Are you authorised to work on the Endeavour Energy network in Seven Hills?
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 Western Sydney.
Does three phase power help with solar and batteries?
Yes. Larger hybrid inverters and battery systems export more efficiently and have more headroom on a three phase connection, which is increasingly relevant as solar uptake grows.
Can you supply three phase power to a home workshop or shed?
Yes. We regularly run dedicated three phase circuits to sheds and workshops across Seven Hills, sized to suit welders, compressors and machinery.
Testimonials
"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.
