Ducted air-con, EV chargers, pool equipment, granny flats — modern homes draw far more than the single phase supply they were originally built with. We're Level 2 ASP electricians upgrading Mettalic homes from single phase to three phase power, safely and compliantly.
Three Phase Power Upgrades Built for Mettalic
Homes throughout the Mettalic area were often connected on a standard single phase supply that's now struggling under modern electrical demand. Pools, ducted air-con, induction cooktops, EV chargers and home offices all pull heavy current, and on an 80–100 amp single phase service that translates into tripping mains, dimming lights and appliances underperforming.
A three phase upgrade gives your Mettalic property the capacity it needs going forward. Current is split evenly across three conductors instead of one, voltage stays consistent under load, and you gain access to equipment a single phase service can't run — three phase EV chargers, heavy workshop tools, large pool heating and commercial-grade appliances.
As authorised Level 2 electricians, we're certified to disconnect and reconnect directly to the network infrastructure serving Mettalic, managing the whole job from quote to energisation with one team.
Why Mettalic Properties Are Upgrading to Three Phase
Properties throughout the Mettalic area are pushing past the limits of their original single phase connections. Here's what typically drives the upgrade:
- Heavy appliance loads — ducted reverse-cycle, pool pumps, spa heaters, instant hot water and EV chargers running concurrently.
- Renovation or knock-down rebuild — new construction locally is increasingly designed around three phase from day one.
- Granny flat or secondary dwelling — a second residence on the block frequently exceeds single phase capacity.
- EV ownership — 11 kW and 22 kW home chargers need three phase supply, and demand keeps growing in the Mettalic area.
- Solar and battery upgrades — hybrid inverters export and perform more efficiently on balanced three phase power.
- Workshops, sheds and home businesses — three phase motors, welders and compressors run cooler and more reliably.

What is a Three Phase Power Upgrade?
Single phase power uses one live wire and typically provides up to 240 volts, adequate for light loads but not optimal for heavier consumption without risking system overload and inefficiency. In contrast, a three phase power system incorporates three alternating currents, equally spaced in phase angle, providing up to 415 volts. This configuration allows for a more consistent delivery of power, as the total power delivered never drops to zero, a distinct advantage particularly in industrial settings or in homes with high energy demands.

Testimonials
"Chris was the professional, punctual and his services are exceptional. Chris re-wired the entire property, chased the electrical work in the bathroom and kitchen areas, left a clean and tidy environment and his open communication and dialogue was a welcomed experience.
When he quoted an arrival time, he was there. He talked me through what he was doing, and provided feedback/suggestions on how to tackle any issues. I felt part of the process, as opposed to being another Customer.
