Why Homeowners Are Upgrading to Three-Phase Power (Mains Upgrade Explained)

Why Melbourne Homes Are Moving to Three-Phase Power

As more homes convert from gas to electric appliances, single-phase power often struggles to keep up. Appliances like EV chargers, induction cooktops, ducted heating, and electric hot water systems all draw significant power. That’s where a three-phase mains upgrade comes in.

A mains upgrade gives your home access to higher electrical capacity, helping you future-proof your property and avoid overloaded circuits or flickering lights when multiple devices run at once.

The Benefits of a Three-Phase Upgrade

• More Power, Less Strain: Three-phase systems provide smoother, more balanced power delivery, ideal for energy-hungry modern homes.

• Supports EV Charging: Most EV chargers perform best with three-phase power, reducing charge times and improving efficiency.

• Perfect for All-Electric Living: As homes switch from gas to electricity, three-phase ensures consistent performance across your induction cooktop, reverse-cycle air conditioning, and hot water system.

• Improved Reliability: Appliances run more efficiently, and large motors (like in HVAC systems) start more smoothly, reducing stress on your circuits.

• Future-Ready: With more electric technologies emerging, a three-phase supply keeps your home compatible for years to come.

When to Consider an Upgrade

If you’ve recently:

• Installed or plan to install an EV charger

• Switched to induction cooking

• Upgraded to ducted reverse-cycle air conditioning

• Noticed frequent circuit tripping or flickering lights
  …it’s worth having a licensed electrician assess your current supply.

What’s Involved in a Mains Upgrade

Your electrician will:

1. Inspect your existing supply and switchboard.

2. Coordinate with your energy distributor to increase your connection capacity.

3. Upgrade your mains cables, meter, and switchboard to handle three-phase power safely.

4. Test and certify everything meets current Australian Standards.
