Acreage blocks, machinery sheds and horse properties around Dural draw a lot more power than the standard suburban home, and single phase supply runs out of headroom fast. We're Level 2 ASP electricians upgrading Dural homes from single phase to three phase power, safely and compliantly.
Three Phase Power Upgrades Built for Dural
Dural homes (2158) are increasingly outgrowing the single phase supply they were built with, a pattern that shows up locally through acreage and workshop demand. 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 Dural property genuine working capacity. Load is spread evenly across three conductors instead of one, voltage stays stable at the shed as well as the house, and you unlock equipment a single phase supply cannot run, workshop machinery, irrigation pumps, large pool heat pumps and machinery sheds all at once.
As authorised Level 2 electricians, we're certified to disconnect and reconnect directly to the Endeavour Energy network that supplies Dural, so the whole upgrade is handled by one team from quote to energised.


Why Dural Properties Are Upgrading to Three Phase
Dural sits within the Hills District, served by the The Hills Shire Council. These are the upgrade triggers we see most often on acreage properties here:
- Machinery sheds, workshops and welders that need three phase motors to run efficiently.
- Irrigation and bore pumps on larger rural residential blocks.
- Pool and spa heat pumps, common on the bigger Dural properties.
- Second dwellings or granny flats for family living on the same acreage.
- New stables, arenas or outbuildings added as a property is developed further.
- EV charger installation for a driveway well away from the front gate.

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
Will my existing switchboard need to be replaced?
Often, yes. Many Dural homes still have an older single phase board that cannot safely accommodate a three phase distribution. We assess this on site and include any switchboard work in the fixed quote.
How much does a single to three phase upgrade cost in 2158?
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.
Can I get a three phase upgrade done on a rented or tenanted property?
Yes, we regularly work with landlords and property managers in Dural. We coordinate timing with tenants and provide all compliance paperwork the agency needs on file.
Are you authorised to work on the Endeavour Energy network in Dural?
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 Hills District.
