If your Jamisontown 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 Western Penrith.
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 Jamisontown (2750)
In the Western Penrith, Jamisontown (2750) is characterised by established family homes and newer estates at the foot of the Blue Mountains. Understanding that housing is half the job when it comes to service-side electrical work.
Around Jamisontown we're regularly called out for three-phase and switchboard upgrades for ducted air conditioning, new estate connections and metering and single-phase supplies struggling with heavy summer cooling loads — all Level 2 ASP work rather than something a general electrician can sign off.
Power to Jamisontown runs through the Endeavour Energy network. Penrith regularly records Sydney's hottest summer temperatures, so peak cooling load makes supply and switchboard upgrades common. Endeavour Energy supplies the Penrith area, mixing overhead residential mains with underground supply in newer estates.

Do You Need Three Phase in Jamisontown?
Three phase is worth considering at Jamisontown 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.
