How Do I Find An Electrical Fault In My House?

Written by Senior Electrician

Electrical faults can be tricky to diagnose. Common issues include flickering lights, dead outlets, and circuits that trip randomly. While some faults are easy to identify, others require professional testing equipment.

Important Safety Warning

Never ignore burning smells or sparking outlets. These are fire hazards. Turn off power at the switchboard and call an electrician immediately.

Common Signs & Symptoms

  • Lights flicker when appliances turn on
  • Specific outlets don't work
  • Circuit breaker trips frequently
  • Burning smell from outlets or switches

Potential Causes

Why is this happening? Here are the most common reasons we see in WA homes:

  • Loose connections in outlets or switches
  • Overloaded circuit (too many devices)
  • Damaged cable from nails, screws, or pests
  • Faulty appliance causing earth leakage

Troubleshooting Steps (DIY Safe)

  • 1
    Unplug all devices and reset the circuit breaker.
  • 2
    Plug devices back in one at a time to identify the culprit.
  • 3
    Check for warm or discolored outlets - these indicate loose connections.
  • 4
    If the fault persists with nothing plugged in, it's a wiring issue - call an electrician.

DIY vs Professional

In Western Australia, it is illegal to perform your own electrical work. While you can change a lightbulb or reset a switch, anything involving wiring or removing fittings must be done by a licensed electrician.
