BAC Group installs and upgrades three-phase power systems for residential and commercial properties across Sydney, coordinating with Ausgrid and other network operators where supply upgrades are required.
When You Need Three-Phase Power
- Large ducted or commercial air conditioning systems
- Workshops with heavy machinery (lathes, compressors, welders)
- Commercial kitchens with multiple large appliances
- EV charging infrastructure — particularly for multiple chargers or fast-charging
- Swimming pools with larger pumps and heating systems
- Properties with solar and battery systems above standard capacity
- Any situation where single-phase supply is insufficient or causing voltage drop
What's Involved
Installing three-phase power typically involves upgrading the supply from Ausgrid (if not already three-phase at the street), installing a three-phase meter and main switch, installing a new switchboard or sub-board for the three-phase circuits, and running the required circuits to the application.
