FAQs

Got a question about electrical fault finding? Let us help.

Flickering doesn’t always mean there’s a fault. Before you call an electrician, check whether the bulb is loose or simply needs replacing. If the flickering continues, the cause could be a faulty light switch, a wiring problem or voltage fluctuations, all of which need an electrician to diagnose.

A dead socket can be caused by a tripped RCD, faulty wiring or a broken socket itself. Check your fuse board first, and if nothing has tripped, book an electrician to inspect the wiring and the socket.

A Residual Current Device (RCD) that trips repeatedly can point to several problems, including an overloaded circuit or a ground fault. Try unplugging your appliances one at a time to see if a particular one is at fault. If the tripping continues, book an electrician to track down the cause.

A burning or fishy smell usually points to a wiring fault, which can be dangerous. Get in touch with a qualified electrician to find and fix the source of the problem.

Humming can be caused by a number of different electrical faults including, loose connections or electrical arcing. If you hear electrical humming coming from your electrics, it’s important to get it checked by a professional.

Switch the power off at the fuse board straight away and stop using the socket. Sparking is a serious fire risk, so turn off the power at the fuse board and contact us as soon as possible to book an emergency inspection.

Electric shocks can be an unpleasant experience and are a sign of an electrical fault. Contact an electrician to inspect your appliance and electrical system to prevent further injury.
