3 Phase Upgrades
Determining whether 3-phase power is right for your property depends on your electrical needs and the type of devices you're planning to run. If your home or business uses heavy machinery, air conditioning systems, electric vehicle (EV) chargers, or other high-powered appliances, upgrading to 3-phase power can provide more efficient and reliable electricity.
Unlike single-phase power, which delivers electricity through a single alternating current, 3-phase power distributes electricity evenly across three alternating currents. This reduces strain on electrical components, improves energy efficiency, and provides a more stable power supply.
Our experienced electricians at SK Electrical handle everything from upgrading your switchboard to liaising with your energy provider to ensure a seamless transition to 3-phase power. We take care of all wiring and safety requirements, ensuring compliance with Australian electrical standards.

Upgrading from Single-Phase to 3-Phase Power
Upgrading from single-phase to 3-phase power can significantly enhance your home or business's electrical capacity. This upgrade supports higher electrical loads and increases power efficiency, especially for demanding appliances.
One of the primary advantages of a 3-phase upgrade is its ability to distribute electricity more evenly, reducing voltage drops and providing a stable energy supply. This is essential for businesses running heavy machinery, commercial kitchens, workshops, or homes with high-powered appliances.
At SK Electrical, we conduct a thorough assessment of your current electrical setup to determine the feasibility of an upgrade. Our expert electricians handle everything from switchboard modifications and meter upgrades to liaising with your energy provider for approval.
By making the switch to 3-phase power, you future-proof your property, ensuring it can handle increasing energy demands as technology advances.

Frequently Asked Questions
How much does a 3 phase power upgrade cost in Sydney?
A typical single-phase to 3-phase upgrade in Sydney costs between $3,500 and $7,500, depending on whether the street supply is already 3-phase, how far the meter is from the switchboard, and what switchboard work is required. We provide an itemised fixed-price quote after an on-site assessment.
How long does a 3 phase upgrade take?
From first site visit to energised supply, most upgrades complete in 2-4 weeks - the physical install is usually 1-2 days, but coordination with your energy provider (Ausgrid) for meter upgrade and connection can take 2-3 weeks. We manage all the paperwork and scheduling.
Do I need 3 phase for an EV charger?
Not for most home EV chargers - a 32A single-phase Level 2 charger (7.4kW) covers almost all overnight charging needs. 3 phase is worth considering if you run multiple EVs, want the fastest AC charging (22kW), or also need 3 phase for ducted aircon, workshop equipment or a pool heater.
Can my street supply 3 phase power?
Most Inner West streets already have 3-phase mains available on the pole - which keeps the upgrade cost to switchboard and metering only. Where 3-phase isn't yet at your boundary, Ausgrid can extend supply but this adds cost and time. We check available supply before quoting.
Will I save money on power bills with 3 phase?
3 phase itself doesn't lower your tariff - you pay per kWh the same. The savings come from efficiency: motors and compressors run cooler and longer, so HVAC and appliances last longer and waste less. For homes with heavy loads, 3 phase also unlocks lower-cost time-of-use tariff options.
