Power out at home? What to do in a blackout

In short

First work out whether the outage is yours or the street's. If the neighbours are dark too, it is the network: check Ausgrid's outage map or call Ausgrid on 13 13 88. If only your home is out, look at your switchboard for a tripped safety switch or main switch. If it will not reset, or you see or smell anything burning, call a licensed electrician.

If you would rather have it checked, Ambient Electrical offers electrical fault finding in Sydney's Eastern Suburbs.

Is it just you, or the whole street?

A blackout has two main causes. Either the network supplying your street has a problem, or there is a fault in your own installation, usually at the switchboard.

Look outside. If the streetlights and your neighbours' houses are dark, the problem is on the network. Across Sydney's Eastern Suburbs, the CBD and the Inner West that network is run by Ausgrid, which posts current outages on its website and takes fault reports on 13 13 88. An electrician cannot fix a network outage.

If only your home is out

  1. Go to your switchboard with a torch. Look for a safety switch or circuit breaker in the down or off position.
  2. If a safety switch has tripped, reset it once. If it trips again, follow the steps in the safety switch guide to find the appliance causing it.
  3. If the main switch is off or will not stay on, leave it off and call an electrician. The main switch can fail from a short circuit on one of the circuits, or simply from age.
  4. If nothing at the switchboard has tripped and the neighbours have power, the fault may be at your service fuse or service mains, the connection to the network. That is network connection work, which in NSW needs an Accredited Service Provider (Level 2).

Do not open the switchboard, remove covers or try to replace fuses yourself. Call from a mobile: cordless and NBN phones usually stop working in a blackout.

Staying safe while the power is out

  • Use a torch or your phone's torch rather than candles
  • Switch off heaters, ovens, irons and other appliances so they do not come back on unattended when power returns
  • Unplug computers and TVs to protect them from a surge when the supply comes back
  • Keep the fridge and freezer doors closed to hold the cold in
  • Never touch power points, switches or cords with bare or wet feet

When a blackout becomes an emergency

If the outage came with a bang, sparks, smoke or a burning smell, treat it as an emergency. Turn off the main switch only if it is safe to reach, keep everyone clear, call 000 if there is fire or anyone is hurt, then call an emergency electrician.

Common questions

Why is my power out but my neighbours have power?

The fault is in your own installation or your connection to the network: a tripped safety switch, a failed main switch, a blown service fuse, or damaged service mains, often after storms or from overgrown trees. Check the switchboard first, then call an electrician.

Who do I call for a power outage in Sydney?

If the whole street is out, it is a network fault: check Ausgrid's outage map or call Ausgrid on 13 13 88. If only your property is out, call a licensed electrician. Ambient takes calls 24 hours a day on 0415 684 120.

What should I do with the fridge during a blackout?

Keep the fridge and freezer closed as much as possible so they hold their temperature. After a long outage, check food safety advice before eating anything perishable.

Can I replace the service fuse myself?

Replacing the service fuse is not a job for a homeowner. The service fuse is part of the network connection, and replacing it is work for an Accredited Service Provider (Level 2). You can check any provider on the NSW Government's ASP search.

Why does my safety switch keep tripping?

A safety switch (RCD) trips when it detects electricity leaking to earth, usually through a faulty appliance, water in an outdoor fitting or damaged wiring.
