Our Consumer Mains Upgrade Services in Marks Point
Single-Phase to Three-Phase
We upgrade undersized single-phase supply to three-phase, giving heavier loads like pools or workshops the capacity they need.
Undersized Mains Replacement
Original mains sized for post-war household demand get replaced with cabling rated for modern appliance and pool pump load.
Pre-Renovation Upgrades
Before a major renovation adds circuits and load, we upgrade the consumer mains so the new switchboard has proper supply.
EV Charger Supply Upgrades
Where an EV charger install is being planned, we upgrade the consumer mains alongside it so the whole system copes.
Pool & Workshop Supply
Adding a pool pump or a home workshop often pushes single-phase supply to its limit, and we upgrade the mains to suit.
Compliance Upgrades
We bring undersized or non-compliant consumer mains up to current AS/NZS 3000 requirements, with full Ausgrid notification.
Why Consumer Mains Upgrade Choice Matters for Marks Point Homes
Getting the mains sized correctly matters because undersized consumer mains cause nuisance trips, dimming lights, and can hold up a renovation or new appliance install:
- Post-war and Housing Commission homes often carry mains sized for lighter, older loads
- Pool pumps and workshop equipment are common additions on peninsula blocks
- Whole-house dimming often points to undersized mains, not a switchboard fault
- AS/NZS 3000 compliance applies to any consumer mains upgrade
- Ausgrid notification is required for any change to phase configuration
Left too long, undersized mains are often behind flickering lights across the whole house rather than a single circuit.

Common Consumer Mains Problems We Fix Across Marks Point
Undersized mains on older homes
Original post-war and Housing Commission properties on the peninsula commonly carry mains sized well below what a modern household now draws.
Whole-house dimming or flickering
Lights dimming across the entire home, not one circuit, usually points to undersized or ageing consumer mains rather than a switchboard fault.
Pools and workshops maxing out supply
Waterfront homes adding a pool pump or workshop regularly push single-phase supply past its limit, requiring an upgrade to cope.
Single-phase supply blocking upgrades
Homeowners wanting an EV charger or larger appliance load often find single-phase mains are the limiting factor, not the switchboard itself.
Non-compliant or ageing mains
Mains that no longer meet current standards can surface as no power to the whole property or trigger a defect notice from Ausgrid or Endeavour Energy.
