Mains Power Upgrade Services Brisbane

Your mains power supply determines the total electrical capacity available to your home or business. Most Brisbane homes are connected to single-phase 63–80A supply — enough for typical residential loads. But if you’re adding an EV charger, large-capacity solar and battery system, workshop equipment, a granny flat, or running a home business with high electrical demands, you may need a mains upgrade.

A mains power upgrade — including upgrading from single-phase to three-phase — requires coordination with Energex and a licensed electrician. Fused Air manages the entire process, from application through to completion.

Frequently Asked Questions

Not always — many homes have enough capacity. We'll assess your existing supply during the free quote and only recommend an upgrade if it's necessary.

The electrical work typically takes 1–2 days. Energex's connection work adds additional time — typically 2–6 weeks depending on the upgrade type and their schedule.

Three-phase power delivers higher capacity and is required for certain high-load equipment. Most homes don't need it, but it's recommended for large EV chargers, large solar/battery systems, some air conditioning units, and workshop or business equipment.

Turn off your main switch if safe to do so, keep everyone away from the affected area, and don't use the electrical system until we've cleared it.
