Is it right for you?
Most Sydney homes run on single phase power, which is plenty for everyday living. Three phase spreads the load across three supplies instead of one, giving your home much more capacity for big appliances running at the same time. If you're weighing up a 3 phase power upgrade, Impulse Electrical Enterprise can look at what you want to run and tell you whether a 3 phase switchboard upgrade in Sydney makes sense. It's usually worth considering for:
Not every home needs three phase. If you just need more circuits and safety switches, or room for solar or a 7 kW EV charger, a single phase switchboard upgrade may be all you need. We'll tell you honestly which one suits your home when we quote.
How it works
We check your current supply, your switchboard and what you want to run, then give you a fixed price before anything is booked.
We arrange the network application for the change to three phase, whether your home is supplied by Ausgrid or Endeavour Energy, and any Level 2 work needed on the network side. You only deal with us, so there's no one else to chase.
We install a new three phase switchboard with safety switches and clearly labelled circuits, and upgrade the cabling from the meter to the board where needed. This 3 phase power installation work usually takes about two days.
We test everything before the power goes back on and give you a Certificate of Compliance for Electrical Work (CCEW) for your records.
Prices
Most 3 phase upgrades cost $7,000 to $11,000+ + GST. We confirm your price in a free, fixed quote before any work starts.
The biggest factors are how far your meter and switchboard are from the street connection, whether the board needs to move and the size of the new board. The work needed on the network side also varies from street to street, which is why we confirm everything in your quote.

It depends on the charger. Single phase home chargers usually top out at around 7 kW, which suits most drivers charging overnight. A 22 kW charger, such as the zappi 22 kW, needs three phase power. We can help you choose the right EV charger for your home.
Most can, but it depends on the supply available in your street. That's checked as part of the network application we arrange for you, and we'll let you know early if there's a problem.
The work itself usually takes about two days, depending on your site. The overall timing also depends on the network's approval, so we give you a timeframe with your quote and keep you updated.
Yes. We take care of the network application, whether your home is supplied by Ausgrid or Endeavour Energy, and organise any Level 2 work, so there's no one else for you to coordinate.
