Supply Upgrades
Single Phase to Three Phase & Capacity Upgrades Across Sydney — EV chargers, ducted AC, and modern loads need an adequate incoming supply.
Modern Sydney homes and businesses are placing unprecedented demand on their incoming electrical supply. EV chargers, ducted air conditioning, pool equipment, workshop machinery, and large-scale renovations all push single-phase services beyond their limits. A supply upgrade — whether increasing amperage or converting from single phase to three phase — requires DNSP approval, Level 2 network-side works, switchboard modifications, and metering coordination.
