Upgrade to Three Phase Power Today
If your current power supply struggles to keep up, it’s time to step up. A three phase upgrade gives you more stable voltage, better support for high-load appliances, and less strain on your system.
From family homes in the Inner West to commercial sites in Parramatta, Pro Electrical upgrades single phase to three phase quickly and with minimal disruption. Our team works with Ausgrid, Endeavour, and local councils to get the job done right—first time, every time.
What is Three Phase Power?
Three phase power is a higher-capacity electrical supply used in homes and businesses that need more than what a standard single phase connection can deliver. While single phase provides one live wire of power, three phase spreads the load across three active wires—allowing for more efficient power delivery, reduced voltage drop, and greater stability under load.
In homes, three phase is ideal for large air conditioning systems, EV chargers, or heavy kitchen appliances. In commercial and industrial settings, it’s essential for powering machinery, motors, and equipment that demand constant, balanced power.
Our Three Phase Services in Sydney
Pro Electrical offers complete three phase solutions for homes, businesses, and industrial properties across Sydney, handled by licensed Level 2 electricians from start to finish. Here’s how we help:
New Phase Installation
We install new three phase connections for residential builds or commercial properties, including overhead or underground cabling, network metering, and a fully compliant connection to the street supply.
System Load Upgrades
For properties with growing power demands, we upgrade your supply from single to three phase to support heavy loads, improve appliance performance, and eliminate underpowered circuits.
Supply Reconfiguration Service
If your site needs a new connection point or better load distribution, we redesign and rewire your existing setup to provide balanced three phase supply throughout the property.
Switchboard Upgrade Integration
When upgrading to three phase, we also replace your switchboard with a modern unit that safely handles increased current and complies with all current Australian electrical standards.
Private Pole Integration
Pro Electrical manages full three phase setup for properties with private poles by upgrading the supply, installing compliant equipment, and handling all required approvals with your energy provider.
Who Needs a Three Phase Upgrade?
Not every property needs three phase power—but for some homes and most commercial setups, it’s essential. If your power supply is underperforming or you’re installing high-demand equipment, here’s where a three phase upgrade makes sense:
Large Air Conditioning
Ducted and multi-head systems often rely on three phase power for stable performance, preventing overloads and keeping your home or business evenly cooled.
Heavy Commercial Equipment
Welders, motors, and industrial tools demand consistent power—three phase prevents interruptions and keeps machinery running at full capacity without strain.
EV Charger Support
Modern EV chargers operate more efficiently on three phase, reducing charging time while keeping the rest of your home’s power supply stable.
Solar System Integration
High-output solar inverters often need three phase to safely manage feed-in and avoid export limitations or load imbalance with the grid.
Voltage Drop Issues
If you notice lights dimming or appliances lagging under load, your current supply may be maxed out—three phase power corrects and stabilises this.
Signs You May Need an Upgrade
If your current electrical system struggles under load or you’re adding high-demand appliances, these signs could mean it’s time to upgrade to three phase power:
Frequent Breaker Trips
If your circuit breakers keep tripping when using multiple appliances or machinery, it’s a strong indicator your single phase system is overloaded and underperforming.
Underpowered Heavy Equipment
When tools, motors, or appliances hesitate or cut out during use, it often means your system lacks the voltage consistency that three phase power provides.
Lights Flicker Frequently
If lights dim or flicker when high-power appliances switch on, it could be due to voltage drop from excessive demand on your existing supply.
New High-Load Appliances
If you’ve recently installed an EV charger, commercial air conditioning, or heavy-duty kitchen gear, your single phase setup may no longer be sufficient.
Maxed Out Supply
If an electrician has warned that your switchboard or cabling is nearing capacity, upgrading to three phase will help future-proof your power infrastructure.
