If your Box Hill property keeps hitting its limit, a three phase upgrade delivers the extra capacity that modern homes and businesses need. SPG carries out single-to-three-phase upgrades right across Blacktown / Northwest.
It's Level 2 work — the supply, consumer mains and switchboard all have to be upgraded and coordinated with Endeavour Energy, which is exactly what we do.
Three Phase Power Upgrade in Box Hill (2765)
In the Blacktown / Northwest, Box Hill (2765) is characterised by a fast-growing blend of established suburbs and brand-new estates across the north-west growth corridor. Understanding that housing is half the job when it comes to service-side electrical work.
Around Box Hill we're regularly called out for high solar and EV uptake pushing supply upgrades, older overhead mains in the established suburbs and new underground estate connections and metering — all Level 2 ASP work rather than something a general electrician can sign off.
Power to Box Hill runs through the Endeavour Energy network. Strong solar and EV adoption plus rapid new-build activity keep connection and supply-upgrade work busy here. Endeavour Energy supplies the Blacktown and north-west corridor, with underground mains in new estates and overhead supply in older streets.
Do You Need Three Phase in Box Hill?
Three phase is worth considering at Box Hill properties running high loads — ducted air conditioning, multiple EV chargers, large solar and battery systems, workshops, or commercial equipment. It spreads load across three supplies for more headroom and smoother running.
We'll assess your current and future load and advise whether an upgrade is warranted — see our supply upgrade service.
