If your Mosman 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 North Shore.
It's Level 2 work — the supply, consumer mains and switchboard all have to be upgraded and coordinated with Ausgrid, which is exactly what we do.
Three Phase Power Upgrade in Mosman (2088)
In the North Shore, Mosman (2088) is characterised by leafy established homes on large blocks under a heavy tree canopy, plus newer apartments near the rail line. Understanding that housing is half the job when it comes to service-side electrical work.
Around Mosman we're regularly called out for storm and branch damage to overhead service lines, private power poles on larger and battle-axe blocks and consumer-mains and three-phase upgrades for extended family homes — all Level 2 ASP work rather than something a general electrician can sign off.
Power to Mosman runs through the Ausgrid network. Falling limbs and wild weather are the most common cause of service-line faults across these suburbs. Ausgrid supplies the North Shore largely overhead, and the mature tree cover through Ku-ring-gai puts service lines at risk in storms.
Do You Need Three Phase in Mosman?
Three phase is worth considering at Mosman 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.

Three Phase Power Upgrade Mosman — Frequently Asked Questions
