Your switchboard is the center of your home’s electrical system, and it's what’s responsible for the safe supply of electricity to every room and appliance in your home. However, like any other electrical component, switchboards can develop faults over time. Tripped circuits, burning smells, and flickering lights are all telltale signs that you need to have a switchboard repair in Sydney. In this guide, we’ll explore some of the most common problems and fixes for switchboard issues. At the same time, we’ll also take a look at whether a repair can be DIY and when you should start on your switchboard upgrades in Sydney.

What are the signs that your switchboards need repair?

Like any other electrical appliance or system, there will come a time when your switchboard needs to be repaired. The good news is that when your switchboard needs repair, you will notice one or more warning signs. When you notice these signs, it's important that you take immediate action, or you will have to face more complex problems down the road.

  • Burning smells and scorch marks—the charring of metal and plastic as well as burning smells can be a sign of overheating or electrical arcing in the system.
  • Buzzing and humming sounds—If you hear unusual humming and buzzing sounds coming from your switchboard, it can be a sign of loose wiring, faulty breakers, or overloaded circuits.
  • Sparking - Any visible sparks in the switchboard can be a precursor to a major system failure. If you notice sparks, shut off the system and call a professional right away.
  • Hot to the touch—If the covers, switches, or cables are hot to the touch and there is a significant color change, it can be a sign of hazardous overloading.

If you notice any one or more of the warning signs mentioned above, the best course of action is to shut down that specific circuit, or the full switchboard if needed, and contact an experienced electrician for a switchboard repair in Sydney.

Is it better to repair or replace your switchboard?

The answer is, it depends. If your switchboard is old and not enough to meet your current electric needs or safety standards, then a breakdown will give you the perfect time to have your switchboard replaced. However, if your switchboard is modern and only a part of it, like a circuit, switch, or wire has been damaged, then repairing the switchboard can be done by replacing the defective component. But if your switchboard has suffered significant damage, then you will need to replace it, no matter how modern it may have been. Let an expert take a look at your switchboard and decide whether it can be repaired or whether you need to go for a new switchboard installation in Sydney.

Can your switchboard repair in Sydney be DIY?

No, switchboard repairs in Sydney cannot be DIY. When your switchboard is only experiencing a minor issue, you might be tempted to try and fix it yourself. However, electrical work can be extremely dangerous, and one wrong move can lead to fire, injury, death, and other forms of lasting damage. Apart from that, there can be issues when you try to claim compensation for the accident caused by unlicensed work. Furthermore, if you are found engaged in unlicensed work, you can be subject to fines and other legal penalties. That being the case, only a licensed electrician has the permission to conduct electrical work, including switchboard repair in Sydney.

When you hire an electrician, you put yourself out of harm’s way. At the same time, when you hire a professional, quality service that conforms to industry standards is almost certainly guaranteed.
