What is the cost to upgrade to 3 phase power from single phase for home owners?

Upgrading from a single-phase to a three-phase power supply can significantly enhance your home’s electrical capacity. Typically, homeowners can expect to pay between $2,500 and $6,000 for the upgrade, depending on various factors such as the complexity of the installation, distance to the nearest three-phase power line, and the specific requirements of your property. This cost includes the installation of a new three-phase switchboard, additional wiring, and necessary paperwork. While the initial investment is considerable, the benefits of a more stable and higher capacity power supply can be worthwhile, especially for homes with high energy demands or plans for future electrical upgrades.

Is it worth upgrading my home to three-phase power?

Switching to a 3-phase power supply can bring several advantages to your home or business.

Here’s why upgrading from a single-phase system is worth considering:

Longer appliance lifespan

3-phase power reduces wear and tear due to lower vibration, extending the life of electromechanical equipment.

Improved electricity efficiency

Switching to 3-phase power significantly improves electricity efficiency. Unlike single-phase power, which relies on one current waveform, three-phase power uses three separate waveforms. This tripling of power capacity enables more balanced electricity distribution, reducing energy losses and optimising the performance of electrical systems. The use of three-phase power keeps the electric supply constant, ensuring a steady and reliable power flow.

With improved efficiency, you can expect lower energy bills and more sustainable electricity use, making the transition to 3-phase power a smart investment for long-term energy savings.

Stable power supply

Ideal for large residential homes, commercial buildings, and manufacturing, 3-phase electricity ensures a consistently distributed load profile.

The advantages of upgrading your home to 3 phase power

As homes integrate more advanced technologies and high-powered appliances, a reliable and efficient electrical system becomes crucial. Upgrading to three-phase power offers a stable and robust power supply that improves the performance of various systems, from ducted air conditioning to electric vehicle charging stations.

Here are the 7 main benefits of upgrading from single phase power:

Rapid electric vehicle charging

As electric cars gain popularity, home charging stations require increased power. A three-phase switchboard boosts your household’s power capacity to meet the additional energy demand, enabling rapid charging.

Three-phase solar inverter and battery storage

Upgrading to solar panels and battery storage is more effective with a three-phase power supply. This setup allows you to produce, store, and use more energy, benefiting from energy-efficient appliances.

Future-proofing your home

Today’s households have increasingly more devices and appliances. A three phase supply provides the option to safely distribute the power demand across multiple phases, allows for greater choice in energy efficient appliances and yields broader options for solar energy and storage.

Ducted air conditioning systems

For larger homes with ducted air conditioning, upgrading to three-phase power can be a smart move. This upgrade allows for more powerful and energy-efficient three-phase AC units.

Pool and heater combination

While not essential for every pool, three-phase power is beneficial if you plan to add high-electricity features. For instance, a large pool heater may require a three-phase setup to meet peak power needs. Consult with us to determine if this upgrade suits your property.

Large home with many appliances

Bigger households naturally have higher electricity requirements due to additional space, plug points, and appliances. Upgrading to a three-phase system prevents circuit overloads, allowing simultaneous use of multiple appliances without tripping the system.

Workshop equipment

High-output machinery often requires a three-phase power supply for its torque and heating demands. It also allows for balanced circuit segregation across phases.

What is the process of upgrading to three-phase power?

If you’re planning to upgrade to a three-phase power system or your new home has significant power demands, Valour Services is here to help. Our team of certified level 2 electricians will support you throughout the entire upgrade process, from planning to execution.

How to know if 3 phase power available in your location?

The electricity networks operating in Sydney have the infrastructure to provide three-phase power to your home. Contact Valour Services for a detailed quote and to schedule the installation.

What you need to know when upgrading to 3 phase power

To connect your property with a 3 phase supply, only an electrical contractor can provide this service. A level 2 electrician will be required to install either underground or overhead power connections.

3 phase power upgrade process

Installing new Service Mains and Consumer Mains cables

The installation begins at the road reserve, with cables running overhead from a Network Pole or underground through a Network pillar or column.

To learn more about the cost and benefits of running underground power, read our article “What is the cost to run underground power?”

Setting up connection pillars, private poles or Point of Attachments (POAs)

Depending on how the electricity on your street is distributed, your level 2 electrician will connect your 3 phase supply either through a private pole or pillar, or straight to a Point of Attachment (POA).

Connecting to the power supply

The new 3 phase service mains cables are connected to the Network Pole or Pillar and then to your meter box, ensuring a consistent and secure electricity supply.

Making the decision to upgrade to 3 phase power

Upgrading your single phase supply to a three-phase supply is a crucial step in enhancing your power system to meet the demands of modern, energy-intensive electrical appliances. Unlike a single phase system, a three-phase system distributes electricity through three active phases and one neutral wire, reducing the risk of an overloaded phase and promoting safer, more efficient energy use. This solution adheres to the stringent Australian standards for electrical safety and efficiency.

Installing a three-phase switchboard offers several benefits. It accommodates the higher load of your household or business equipment and sets the foundation for future expansions. This ensures your property has a power system that can handle today’s needs as well as tomorrow’s. Additionally, three-phase appliances are more energy efficient than single-phase ones, providing long-term economic benefits.
