    Does Your Property Need a 3 Phase Power Upgrade?

    Single phase power at 230V works for everyday appliances, but it struggles with EV chargers, ducted AC, solar systems, or heavy machinery. A three phase upgrade brings 400V across three conductors — the capacity your property actually needs.

    Heavy Electrical Loads: Ducted air conditioning, electric hot water systems, and industrial ovens overload single phase. Three phase spreads the load evenly, stopping tripped circuits and overheating before they start.

    EV Charging Infrastructure: Three phase EV chargers deliver up to 22kW vs 7.4kW on single phase — cutting a 60kWh charge from 7+ hours to under 3. Essential for any property planning EV charging.

    Solar & Battery Systems: Ausgrid permits up to 10kW per phase on three phase supplies — meaning up to 30kW solar generation in NSW. Three phase is essential for large solar and battery storage setups.

    Commercial & Industrial Use: Businesses running HVAC, lifts, and production equipment simultaneously need the stable balanced voltage of three phase to avoid voltage drops and frequent breaker trips.

    Workshop Machinery: Three phase motors in compressors, lathes, and pumps run more smoothly, generate more torque, and last longer — the balanced voltage reduces mechanical stress and heat buildup.

    Renovations & New Builds: Upgrading during a renovation is far more cost-effective than retrofitting later. Future-proof your property against growing power demands and add resale appeal for buyers with high electrical needs.

    Signs You Need a Three Phase Upgrade

    A three phase upgrade makes sense once your property’s electrical demand regularly pushes past what single phase can handle. Here are the clearest signals.

    Circuit breakers tripping regularly means your single phase supply is already at capacity. Three phase distributes that demand across three conductors and stops nuisance trips.

     

    Single phase maxes at 7.4kW per charger. Three phase brings that to 22kW — cutting charge time by over 60%. Any property adding one or more EVs should upgrade.

     
     

    In NSW, Ausgrid allows up to 10kW per phase — meaning three phase allows up to 30kW of solar exports. Single phase is capped at 10kW, limiting your solar return.

     

    Compressors, lathes, and industrial air conditioning are engineered for three phase. Running them on single phase causes overheating, poor torque, and premature failure.

     
     

    Adding ducted AC, a larger kitchen, a workshop, or significant new circuits during a renovation is the most cost-effective time to upgrade — far cheaper than retrofitting later.

    Multiple HVAC units, servers, commercial kitchen equipment, and office loads running simultaneously demand the balanced, stable supply that three phase provides.

    Frequently Asked Questions

    Everything homeowners and business owners typically ask before booking a three phase upgrade in Sydney.

    How much does 3 phase upgrade cost in Sydney?
    The total cost depends on your property’s existing infrastructure, cable run distances, and the full scope required. Switchboard upgrades range from $750 to $1,800, consumer mains from $450 to $1,400, and Level 2 ASP labour from $1,000 to $2,200. We charge $0 for call-outs and site assessments. Contact us for a fixed, itemised quote specific to your property.
     
    Yes. Under the Gas and Electricity (Consumer Safety) Act 2017 and NSW Service and Installation Rules, all three phase electrical work must be carried out by a licensed electrician. Network-side connections — from the street to your meter — can only be done by an Ausgrid or Endeavour Energy accredited Level 2 ASP. Unlicensed work carries fines of up to $22,000 for individuals and $110,000 for companies, and cannot be retrospectively certified.
     
    Most three phase upgrades are completed within one to two days on site. The main variable is the network application processing time with Ausgrid or Endeavour Energy, which typically takes one to two weeks. We manage this application for you and keep you updated throughout the process.
     
    There will be a planned outage during the installation — typically a few hours. We schedule this at a time that minimises disruption to your household or business operations, and we advise you of the expected outage window well in advance.
     
    In most cases, yes. Single phase switchboards are not rated for three phase supply. We will assess your existing board during the site visit and advise whether it needs a full replacement or modification. Modern switchboards with the correct circuit breakers, RCDs, and surge protection are a mandatory part of a compliant three phase installation.
