Quick Answer

Journey Electrical installs three-phase power upgrades across Newcastle, Lake Macquarie, Maitland, and surrounding areas. Upgrading from single to three-phase power requires a formal Ausgrid application and Level 2 Accredited Service Provider credentials. As an Ausgrid Accredited ASP holding all four Level 2 categories, we manage the complete project — network application, consumer mains upgrade, and switchboard work — under one contractor.

Self-Assess

Do You Actually Need Three-Phase Power?

Most homes run perfectly well on single-phase power. But single-phase has a ceiling, and if you’re adding high-draw equipment, you can hit it faster than you’d expect.
Three-phase power delivers three times the capacity of a standard connection. It’s not always necessary, but when it is, it’s the only solution that actually works.

“Not sure whether your setup requires it? Call us and describe what you’re trying to run — in most cases, we can give you a straight answer over the phone without a site visit.”

EV Fast Charging

22kW chargers need three-phase. Single-phase maxes at 7kW, adding hours to every charge.

Ducted Air Conditioning

Multi-zone ducted reverse-cycle A/C draws high startup loads that can overwhelm single-phase circuits.

Solar Over 10kW

Single-phase caps your export capacity. Three-phase lets your system send more back to the grid.

Pool, Spa or Sauna

These run constant, high-draw loads that stack up fast on a single-phase connection.

Home Workshop & Industrial Equipment

Lathes, welders, compressors and industrial machinery commonly require three-phase supply to operate at full capacity.

How It Works

What's Involved in a Three-Phase Upgrade?

There are two distinct scopes of work — and most contractors can only handle one of them. We handle both.

01

Ausgrid Network Application

Three-phase starts at the street. A formal application must go to Ausgrid and the meter provider before any physical work begins.

Level 2 Accredited only

02

Consumer Mains & Service Upgrade

Once Ausgrid approves, the physical mains work proceeds — new cables, service fuse, meter installation, and three-phase main switch.

Level 2 licensed work

03

Switchboard Commissioning

The upgraded supply feeds into a new switchboard with the correct circuit breakers and RCD protection for three-phase operation.

General electrical

Charging Output Comparison

  • Ausgrid network connection upgrade
  • Meter provider application
  • All documentation prepared and submitted
  • ~2 week approval turnaround

Step 2 — Mains Work

  • Service mains cable replacemen
  • Point of attachment upgrade
  • Service fuse and meter installation
  • New three-phase main switch

Step 3 — Switchboard

  • New switchboard installation
  • Three-phase circuit breakers
  • Full RCD protection
  • Same day as mains work where possible

Because we hold both Level 2 accreditation and a standard electrical licence, the entire job is managed by one contractor. You don’t coordinate between trades, explain the project twice, or worry about who’s responsible for what.

EV Charging

Three-Phase Power for EV Charging in Newcastle

A standard single-phase EV charger tops out at around 7kW — enough to charge overnight, but not much faster. If you want meaningful daytime charging speed, you need more.
A 22kW three-phase EV charger will charge a typical EV to full in under two hours. But to run one, your home needs three-phase power at the switchboard — and that means a full connection upgrade, not just a charger installation.

We assess your current setup, advise on the minimum upgrade required, and manage the entire job — Ausgrid application, consumer mains, switchboard, and charger wiring — as a single, coordinated project. No third parties, no coordination gaps.

Single-phase (7kW)

~8–10 hrs for full charge

Three-phase (22kW) — Zappi

Solar Integration

Maximise Your Solar Investment With Three-Phase Power

There’s a common misconception with larger solar systems: installing more panels doesn’t automatically mean more export. Single-phase connections have a physical export limit — and if your system is generating more than the mains can carry, that energy doesn’t go back to the grid. It’s wasted.
Upgrading to three-phase power allows significantly more export capacity and better interaction with the grid, which means better returns on a larger system.
We work alongside solar installers as the Level 2 ASP on residential and commercial solar projects — handling the Ausgrid application and consumer mains upgrade so the installation can proceed without delays.

Why Journey Electrical

The Credentials That Make the Difference

A three-phase upgrade touches scopes that most contractors can’t complete alone. Here’s why we can.

6807

Ausgrid Accredited ASP

Accredited — not just Authorised — means a broader scope of Level 2 work and access to the network applications required for three-phase. Accreditation number 6807.

4/4

All Four Level 2 Categories

Metering, overhead, underground, and consumer connections — all held under one contractor. A three-phase upgrade touches every one of these categories.

Cable Locator

In-House Cable Locator

If underground cable location is required before excavation, we carry our own equipment. No third-party locator, no delays, no additional contractor to schedule.

5yr

Heavy Industry Background

Our director spent five years managing electrical operations across Australia’s mining and heavy industry sector. Three-phase residential work is routine by comparison.

Common Questions

Three-Phase Power — Frequently Asked Questions

Answers to the questions we’re asked most often before a three-phase upgrade.

1

Do I need three-phase power for an EV charger?

It depends on the charger. A standard 7kW single-phase charger doesn’t require a three-phase connection — but if you want to install a 22kW fast charger, you’ll need three-phase power at the switchboard. If you’re not sure what charger you’re buying, call us before ordering any hardware — it’s a quick conversation that can save a lot of rework. And it normally works out cheaper for our clients.

2

How much does a three-phase upgrade cost in Newcastle?

Three-phase upgrades aren’t a fixed-price job — the cost depends on your property’s existing infrastructure, how far the mains run from the street, whether underground cable location is required, and the scope of any switchboard work. Simple residential upgrades typically start from several thousand dollars, while larger jobs involving full mains replacement and switchboard upgrades can be significantly more. We’ll give you a clear scope and cost estimate after assessing your property.

3

How long does a three-phase upgrade take?

The Ausgrid application process typically takes around two weeks from submission to approval — this is the longest part of the project. Physical work on-site can usually be completed in a single day once approval is granted. We’ll keep you updated throughout and confirm your job schedule as soon as approval comes through.

4

Do I need Ausgrid approval for three-phase power?

Yes. Three-phase power requires a formal application to Ausgrid to upgrade the network connection at your property — this cannot be bypassed. An Ausgrid Accredited ASP can submit this application and perform the associated mains work. We manage the entire application process, so you don’t need to contact Ausgrid directly at any point.

5

What's the difference between single-phase and three-phase power?

Single-phase power delivers electricity in one continuous wave — it’s what most homes in Australia run on, and it’s perfectly adequate for standard appliances. Three-phase power delivers electricity across three staggered waves simultaneously, giving your home three times the capacity. This is what makes it possible to run high-draw equipment like 22kW EV chargers, large ducted air conditioning systems, or solar systems that export significant power back to the grid.

6

Will my solar system work better with three-phase power?

If your solar system is larger than around 10kW, yes — single-phase connections limit how much power you can export at any one time. Upgrading to three-phase increases your export capacity, which means more of what your system generates actually goes back to the grid rather than being curtailed. If you’re planning a larger solar installation, it’s worth discussing the three-phase upgrade at the same time to avoid doing the mains work twice.

7

Can one electrician handle the whole three-phase upgrade?

Most electricians can only handle part of it. A three-phase upgrade involves both Level 2 accredited work (the Ausgrid application and consumer mains upgrade) and general electrical work (the switchboard). These are two separate licence categories, and many contractors only hold one. Journey Electrical holds both — we manage the complete project from Ausgrid application through to switchboard commissioning under one contractor, which means no coordination between trades and one point of contact throughout.

8

Is three-phase power available in my area of Newcastle?

Three-phase is available across most of the Newcastle and Lake Macquarie network — but availability at the street level can vary by suburb and even by street. In some older areas, the overhead service may only provide single-phase to the point of attachment, and an upgrade may require additional network work by Ausgrid. We check availability as part of the Ausgrid application process. Call us with your address and we can give you a preliminary assessment.
