Pool heating, ducted air-con, EV chargers, workshops — households drawing this much power are outgrowing single phase supply fast. We're Level 2 ASP electricians upgrading Griffith homes from single phase to three phase power, safely and compliantly.
Three Phase Power Upgrades Built for Griffith
Griffith properties on a standard single phase supply are increasingly finding it can't keep up with modern electrical demand. Pools, ducted air-con, induction cooktops, EV chargers and home offices all draw heavy current, and on an 80–100 amp single phase service the result is tripping mains, dimming lights and appliances struggling to perform.
Upgrading to three phase power gives your Griffith property the capacity it needs for the years ahead. Load is spread across three conductors instead of one, voltage stays steady under demand, and you unlock equipment a single phase supply can't handle — three phase EV chargers, workshop machinery, large pool heat pumps and commercial-grade appliances.
As authorised Level 2 electricians, we're certified to disconnect and reconnect directly to the network infrastructure serving Griffith, handling the entire upgrade from quote through to energisation.
Why Griffith Properties Are Upgrading to Three Phase
Properties in the Griffith area are increasingly running into the limits of their original single phase connections. Here's what typically triggers an upgrade:
- Heavy appliance loads — ducted reverse-cycle, pool pumps, spa heaters, instant hot water and EV chargers running together.
- Renovation or knock-down rebuild — new builds in the Griffith area are increasingly specified with three phase supply.
- Granny flat or secondary dwelling — a second residence on the property often exceeds single phase capacity.
- EV ownership — 11 kW and 22 kW home chargers require three phase supply, and adoption is climbing in Griffith.
- Solar and battery upgrades — hybrid inverters export more efficiently and last longer on balanced three phase power.
- Workshops, sheds and home businesses — three phase motors, welders and compressors handle sustained load 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.

"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.
