Guide

Power out in part of the house?Check the switchboard, then check the street.

If only part of the house has lost power, the usual cause is a safety switch or circuit breaker that has tripped. Check your switchboard, unplug things in the dead rooms, and reset the switch once. If the whole house is out, look next door: if the neighbours are out too, it's the network, so you call its faults line, not an electrician.

Updated 29 October 2026 · Written by the Sparky Next Door team · How we check our facts

Sparks, smoke or a hot smell at the switchboard? Don't reset anything

Keep away from the switchboard and leave everything as it is. If there's smoke or fire, get out and call 000. If a power line is down, stay at least 8 metres away (Evoenergy in the ACT says 10 metres), keep others back and call your network straight away.

What to check, in order

  1. Look next door

    If the street is dark, it's a network outage. Check your network's outage map or call its faults line from the table below. There's nothing an electrician can do until the supply is back.

  2. Open the meter box door

    Look for a switch that's down or sitting halfway. A safety switch has a test button and a circuit breaker doesn't. Note which one has gone.

  3. Unplug the dead rooms

    Switch off and unplug everything in the rooms without power. A faulty appliance is the usual reason a safety switch trips.

  4. Reset it once

    Push the switch firmly back on. If it holds, plug things back in one at a time to find the culprit, as our tripping guide explains. If it won't stay on even with the rooms unplugged, that's a fault for an electrician.

  5. Nothing tripped? Check the main switch

    If the main switch is off, switch it on once. If the house is still dark and the neighbours have power, the fault may be in your supply or main connection, so call your network first and an electrician second.

Half the house is out, but nothing has tripped

Older homes sometimes have ceramic fuses instead of circuit breakers, and a blown fuse gives no visible sign from the outside. Queensland and the ACT don't count changing a fuse as electrical work, but on an old ceramic board we'd still call an electrician. Ausgrid says to call one straight away if fuses keep blowing.

On a three-phase home, losing one phase of the supply can drop some circuits while the rest keep going. That's a supply or main connection fault for the network or an electrician to find, not something to fix at the board.

What you can do, and what's an electrician's

You can

  • Check the neighbours and your network's outage map.
  • Reset a tripped safety switch, circuit breaker or main switch once.
  • Unplug appliances to find a faulty one.
  • Call the network about a street outage or a fallen line.

Leave to a licensed electrician

  • A switch that won't stay on with everything unplugged.
  • Old fuses, breakers or safety switches that need replacing.
  • Any burning smell, heat or damage at the switchboard.
  • Finding why part of the house is dead when nothing has tripped.

Where we'd look first

Neighbours first, switchboard second. Those two checks sort out most outages in a few minutes. If a switch won't stay on with everything unplugged, or part of the house is dead with nothing tripped, we'd stop there and call an electrician who does fault finding, because something between the board and those rooms has failed.

Questions

Straight answers.

Why has half my house lost power?

Usually one safety switch has tripped and taken all the circuits it protects with it. If nothing has tripped, it could be a blown fuse on an older board, or a fault on one phase of a three-phase supply. Both need an electrician or your network.

Someone at home relies on life support equipment. What should I do?

Make sure your retailer and network know about it. AusNet runs a separate life support priority line on 1800 818 832, and TasNetworks takes calls about faults affecting life support equipment on 132 004. If someone's life is at risk, call 000.

Can I claim for a long outage?

In WA, the State Government's extended outage payment, run by Western Power, applies to network outages lasting 12 continuous hours or more, and claims must be lodged within 60 days. We haven't confirmed similar schemes in other states.

The power came back but one room is still dead. Why?

Something may have tripped when the supply returned, or an appliance was damaged. Check the switchboard again and reset once. If it won't hold, call an electrician.
