A renovation or extension is one of the most common times we get called out to Maroubra, once the added loads make it clear the existing single phase supply is maxed out. We're Level 2 ASP electricians who upgrade Maroubra homes from single phase to three phase power, safely and signed off to code.
Three Phase Power Upgrades for Maroubra Homes
A renovation or extension is one of the most common times we get called out to Maroubra (2035). Once the new kitchen, ducted air conditioning, extra bathroom and EV charger are all accounted for, the existing single phase supply is often maxed out before the fit off is even finished.
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 Maroubra, so the whole job is handled by one team from quote to energisation.
Why Maroubra Properties Are Upgrading to Three Phase
Maroubra sits within the Eastern Suburbs area, under Randwick City Council, and is supplied by Ausgrid. These are the upgrade triggers we see most often on 2035 switchboards:
- 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.
- EV ownership, with 11 kW and 22 kW home chargers requiring three phase supply and becoming a lot more common in local driveways.
- Solar and battery upgrades, since modern hybrid inverters perform better, export more and last longer on a three phase supply.
- Mains that trip regularly once the air conditioning, oven and another large appliance are running together.
- Lights that visibly dim across the house whenever a large appliance or the air conditioning compressor starts up.

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 Maroubra 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 2035?
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 Maroubra garages, yes, three phase is required.
Are you authorised to work on the Ausgrid network in Maroubra?
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 Eastern Suburbs area.

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.
