Consumer mains upgrades, including single-phase to three-phase conversions, connect directly to the Ausgrid network, and only a Level 2 ASP is licensed to carry them out.

Older cottages around the Avondale Estate and original village were built for far lighter loads than a modern home carries today, and newer Watagan Park homes with pool pumps, workshops and EV chargers can quickly max out a standard single-phase supply. Our Level 2 team sizes the upgrade to genuinely match your household's needs, including the larger rural-residential blocks stretching toward the Watagan foothills.

Our Consumer Mains Upgrade Services in Cooranbong
Supply Capacity Assessment
We assess your existing consumer mains against your current and planned electrical load before recommending an upgrade.
Single-Phase to Three-Phase Conversion
Where a single-phase supply is maxed out, we upgrade to three-phase for genuinely higher capacity.
Underground & Overhead Upgrades
Whether your mains run overhead or underground, we upgrade the run to carry the extra load safely.
EV Charger & Workshop Sizing
Mains are sized to comfortably support an EV charger, home workshop, pool pump or larger appliances.
Switchboard Coordination
We coordinate the mains upgrade with any required switchboard work so the whole supply chain matches.
Ausgrid Approval & Coordination
We manage the Ausgrid approval and any outage booking needed to complete the upgrade safely.
Acreage & Rural Load Planning
Larger rural-residential properties adding sheds, pumps or workshops get mains sized for the full spread of the block.
Compliance Testing
Every upgraded mains connection is tested and certified compliant before we sign off and hand back the completed job.
Why Consumer Mains Upgrade Choice Matters for Cooranbong Homes
Getting the mains upgrade right matters for households adding modern load across older and newer streets:
- Original mains on pre-1940 and mid-century cottages were sized for far lighter loads
- A maxed-out single-phase supply can cause whole-house dimming or dropouts
- Adding an EV charger, pool pump or workshop can push an old supply past its limit
- AS/NZS 3000 governs exactly how a mains upgrade must be sized and installed
- Larger acreage blocks often need extra capacity for sheds and outbuildings
- Workmanship and materials vary significantly between installers

Common Consumer Mains Problems We Fix Across Cooranbong
Undersized mains on older cottages
Homes near the Avondale Estate and original village often still run mains sized for a 1960s household, well under what modern appliances need.
Whole-house dimming or flickering
When flickering lights happen across the whole home rather than one circuit, undersized or ageing consumer mains are a common cause.
No power to the whole property
A loose neutral or failing connection at the mains can cause no power to the whole property, which our Level 2 ASPs isolate and fix.
Circuits tripping under new load
Adding a pool pump, EV charger or workshop to a maxed-out supply leads to overloaded power points, often resolved with a mains upgrade.
Single-phase supply maxed out
Larger Watagan Park homes and acreage properties adding significant load often need a single-phase to three-phase conversion to keep up.
Ageing mains failing under demand
Decades-old mains that have never been upgraded can fail outright once modern load is added, and we replace them before that happens.
Rural blocks outgrowing their original supply
Acreage properties adding a bore pump, workshop or shed circuit often discover the original mains were never sized for it, and we upgrade to match the new load.
