EV Charger Installation
Home charging should be sized around the property, the vehicle and the electrical installation — not just the charger nameplate.
Start with the existing electrical installation
An EV charger adds a substantial continuous load. Before installation, the existing supply, switchboard, circuit protection and maximum demand need to be considered so the charging arrangement suits the property.
32 A single-phase charging
From 1 October 2026, Ergon Energy withdrew the previous active-management requirement that applied to a single-phase 32 A EV charger under the referenced QECM clause. That does not remove the need to recalculate maximum demand or address supply and protection limitations.
What we can look at
- Preferred charger location and cable route.
- Existing switchboard condition and available capacity.
- Maximum demand and potential load constraints.
- Dedicated circuit and required protection.
- Whether a network application, supply change or alternative charging strategy needs consideration.
