Common Electrical Problems In Residential Homes

16 February 2022

Electrical faults are a part of life and when they occur, we need to get to the root cause. Not just for convenience, but for the health and safety of your family.

Let's take a look at what to look for, and how to safely investigate the electrical fault.

A disclaimer that any complex fault finding or touching of any live wires, must only be performed by a licenced electrical contractor. DJL Electrical are available to perform any fault finding that you will require.

Electrical surges throughout the home

Electrical surges occur by a variety of causes, including damaged power lines, lightning strikes, poor or outdated wiring, and the most common, faulty appliances.

Your typical surge lasts for less than once second, although this is long enough to cause substantial damage to your electrical system and/or appliances.

In the event of frequent electrical surges, the most likely cause will be a faulty appliance. If this happens, simply unplug each appliance one at a time (resetting the fuse board if needed) until you track down the offending item.

Having done this and it still happens, then it could be your wiring. In this case, please call a suitably licenced electrician for help.

Light switches not working

Plenty of homes have a mysterious light switch that doesn't seem to tun on any lights, but it's been like that for as long as anyone can remember. It's possible that this is a relic of a fixture that has long been removed. It could also serve a current fixture and the switch is not sending power to it. Engage an electrician, as either the switch or the wiring needs to be addressed.

Circuits overloading

Particularly in older homes, overloaded circuits are common. TV's, Air Con, charging various devices, multiple fridges, air fryer, and the list goes on.

You either need to accept the limitations of your outdated wiring circuits and load them to an acceptable level, or you will need to engage an electrician who could look at adding additional circuits to your home to cater for your higher demand.

In the event of frequent tripping of your circuit breakers:

  • Unplug appliances that are not in use
  • Spread out appliances over different circuits (try different rooms)
  • Do not connect multiple power boards together
  • Avoid long extension leads. Keep them as short as possible

Do your light bulbs burn out quickly?

If you are experiencing light bulbs not lasting as long as what the manufacturer expected, then it's possible that the wattage of the bulb may be higher that what the socket can handle.

You can take a look at any building plans you may have, providing they show the electrical diagram and details for the home.

This could easily be a wiring issue, in which case you will need to engage the services of a licenced electrician, such as the team here at DJL Electrical.

If in doubt about any electrical problem in your home, we urge you not to provide any DIY maintenance (as it's usually illegal).
