Our experienced electricians handle three phase power installations for homes and businesses across Perth. Unlike a standard single phase supply, which delivers electricity through a single active conductor, a 3 phase power installation uses three separate conductors, giving a property around three times the capacity and a more stable, balanced supply. This makes it well suited to running high-demand equipment without overloading circuits or causing tripping.
As licensed electricians in Perth, we manage 3 phase power installations with quality and in line with Australian standards.
Many properties are built and wired with single phase, however upgrading from single phase to 3 phase is becoming increasingly popular in Perth. A 3 phase power upgrade involves new switchboard work, consumer mains and metering, all completed by our licensed electricians. If you’re ready to upgrade to three phase power, contact our expert team today.
While three phase power was once mainly found in commercial and industrial settings, a 3 phase domestic installation is becoming increasingly common in Perth homes. The shift is largely driven by the high-draw appliances households are adding, including ducted reverse-cycle air conditioning, induction cooktops, pool pumps, and EV chargers.
A single phase supply can struggle when several of these run at once, which often results in power trips or slow appliance speeds. Choosing to install 3 phase power at home spreads the load evenly across all three phases, letting everything run smoothly while leaving plenty of capacity in reserve. For both new and existing properties, a 3 phase electrical installation is a practical way to future-proof your home.
For most homes, a 3 phase power installation cost in Perth can fall between $3,000 – $8,000, though the final figure varies considerably depending on what’s already in place at your property. As most jobs involve moving from an existing single phase supply, the cost to upgrade to 3 phase power is largely determined by how much work is required. The main factors affecting both your 3 phase upgrade cost and the overall cost of installing 3 phase power include:
