Spa pumps, ducted air-con, EV chargers, granny flats — if your household is outgrowing its single phase supply, it's time to upgrade. We're Level 2 ASP electricians upgrading Calkendor homes from single phase to three phase power, safely and compliantly.
Three Phase Power Upgrades Built for Calkendor
Many Calkendor properties were originally connected with a modest single phase supply that's now under real pressure. Pools, ducted air-con, induction cooktops, EV chargers and home offices all draw significant current, and on an 80–100 amp single phase service the strain shows up as tripping mains, dim lighting and appliances that can't reach full performance.
Upgrading to three phase power gives your Calkendor property the capacity modern living requires. Load is shared across three conductors instead of one, voltage stays firm under demand, and heavier equipment becomes viable — three phase EV chargers, workshop machinery, large pool heat pumps and commercial-grade kitchen gear that a single phase service simply can't sustain.
As authorised Level 2 electricians, we're certified to disconnect and reconnect directly to the network infrastructure serving Calkendor, delivering the whole upgrade — quote through to energisation — with one team.
Why Calkendor Properties Are Upgrading to Three Phase
Properties around Calkendor are increasingly bumping up against single phase limits. The most common triggers we see are:
- 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 locally are frequently designed around three phase supply from the outset.
- Granny flat or secondary dwelling — a second residence on the property often pushes demand past single phase limits.
- EV ownership — 11 kW and 22 kW home chargers require three phase supply, and they're becoming more common in the area.
- Solar and battery upgrades — hybrid inverters export and perform more efficiently on a balanced three phase connection.
- Workshops, sheds and home businesses — three phase motors, welders and compressors run more efficiently and last longer.

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.
