Discover common household electrical issues like frequent surges, sags, faulty switches, and more. Learn what to do about them and when to call a Brisbane electrician for expert help
Frequent Electrical Surges
Electrical surges can overload your wiring, appliances, or electrical fittings, often causing burns or fires. They’re common during thunderstorms, but if you’re experiencing frequent surges, you might have a faulty surge protector or a failing appliance. Try unplugging your appliances one at a time and check for signs of power surges. If you can’t find the source or smell burning, switch off the power and contact an electrician.
Sags and Dips
Sags, also known as dips, are temporary drops in voltage supply. At home, this often appears as a brief dimming of your lights, though other appliances can also be affected. Voltage sags often occur when power-hungry appliances, like heaters, air conditioners, and fridges, are turned on. While small dips are normal and usually unnoticeable, frequent or large sags need investigation.
Most sags are caused by faulty appliances or wiring creating short circuits or drawing excessive power. Identify which appliances are causing dips by turning them off and then on, and observe for any signs of a dip. Consult an electrician to determine whether the fault lies with the appliance or the wiring in your home.
Faulty Light Switches
Light switches and power points wear out over time due to frequent use. The switches can break visibly, or their internal wiring can fail, rendering them useless. Usually, the fix is to replace the faulty switch. Light switches are affordable, and your electrician can replace the broken one without much fuss.
Circuit Breakers Tripping
Circuit breakers protect your home from various electrical issues. If your circuit breakers trip, typically, you only need to flip them back on. However, if the switch trips regularly or can’t be turned back on, it’s likely due to an appliance or wiring fault.
Note which circuit is tripping, unplug the appliances powered by that circuit, and then flip the switch back on. If it stays on, one of your appliances is probably the issue. Common culprits include irons, cooking equipment, heaters, and straightening irons.
Overloaded Circuits
Each house is divided into separate electrical circuits, each designed to carry a certain amount of power. If you draw too much power, the circuit breaker will trip to protect your wiring from damage. Short circuits in faulty appliances often cause overloading, but it can also result from chaining together extension cables or plugging in too many power-hungry devices on one circuit.
Electric Shocks
Fortunately, most shocks people receive around the home are minor. If you’re being zapped by appliances, wiring, or light switches, you should consult an electrician immediately.
