Plenty of Bexley North homes are still running on the same single phase supply they were built with decades ago, long before ducted air conditioning, EV chargers and induction cooktops became the norm. We're Level 2 ASP electricians who upgrade Bexley North homes from single phase to three phase power, safely and signed off to code.
Three Phase Power Upgrades for Bexley North Homes
Many Bexley North homes (2207) were built with a single phase 60 to 80 amp supply, which was plenty for the appliances of the time but not for a household running ducted air conditioning, an induction cooktop, an EV charger and a home office all at once. When that happens, the usual signs are mains that trip under load, lights that dim when the air conditioning starts, and appliances that seem to run slower or wear out faster than they should.
Upgrading to three phase power spreads the load evenly across three conductors instead of one, so voltage stays stable and you get the headroom to run demanding equipment like three phase EV chargers, workshop machinery and larger pool heat pumps without drama. As authorised Level 2 electricians, we're certified to disconnect and reconnect directly to the Ausgrid network that supplies Bexley North, so the whole job is handled by one team from quote to energisation.


Why Bexley North Properties Are Upgrading to Three Phase
Bexley North sits within the St George area, under Bayside Council, and is supplied by Ausgrid. These are the upgrade triggers we see most often on 2207 switchboards:
- An older home still wired for the original 60 to 80 amp single phase supply it was built with, long before modern appliance loads existed.
- A renovation, extension or rebuild that adds a new kitchen, extra bathroom or additional living space to the home.
- A granny flat or secondary dwelling on the block, which pushes total demand well past what the original single phase supply was designed for.
- 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.
- Heavy appliance loads, ducted reverse cycle air conditioning, spa heaters, instant hot water and EV charging all running at the same time.

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 Bexley North 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 2207?
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 Bexley North garages, yes, three phase is required.
Are you authorised to work on the Ausgrid network in Bexley North?
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 St George area.
