Electrical Faults That Cause House Fires & How to Prevent Them

Every year, thousands of house fires across Australia are caused by preventable electrical faults. These incidents not only result in costly property damage but also pose life-threatening risks to families. Understanding how electrical faults occur and knowing what to look for can help protect your home, loved ones, and investment.

In this blog post, we’ll explore the common causes of electrical fires, the warning signs of electrical hazards, and why regular inspections by a licensed electrician are essential to safety.

🔥 Common Electrical Faults That Can Cause House Fires

1. Overloaded Circuits

When too many appliances draw power from a single point or circuit, it leads to overheating. This situation can spark a fire. This problem is especially common in older homes with outdated switchboards or insufficient electrical wiring capacity.

2. Faulty Wiring

Aged, frayed, or damaged wiring can short circuit and create heat buildup behind walls. Wiring that doesn't meet current Australian electrical standards is a major risk factor.

3. Loose Connections

Poor electrical connections in power outlets, light switches, or junction boxes can cause arcing. Arcing involves sparks jumping from one wire to another. Over time, this can ignite nearby insulation or timber framing.

4. Faulty Appliances

Old or damaged appliances—such as heaters, toasters, and washing machines—can malfunction. This is especially dangerous if these devices are left plugged in or running unattended.

5. Defective Circuit Breakers or Fuses

A faulty circuit breaker may fail to trip during a surge or overload. This allows dangerous levels of current to flow through the system unchecked, increasing fire risk.

🔍 What Should Be Checked by a Licensed Electrician?

To prevent electrical fires, it’s crucial to have your home regularly inspected by a licensed electrician. During an electrical safety inspection, a professional should check:

• Switchboards and RCDs (Residual Current Devices): Ensure your switchboard is compliant and safety switches are functioning correctly.

• Electrical wiring: Look for damaged, outdated, or overloaded wiring.

• Power points and light switches: Identify heat damage, loose terminals, or discoloration.

• Smoke alarms: Confirm they are installed in the correct locations and are in working order.

• Appliance testing and tagging: For any plug-in devices or equipment in frequent use.

• Earthing and bonding: Verify that all metal parts are properly earthed to prevent electric shocks.

• Thermal imaging: Detect overheating components before they become fire hazards.

• Your home is over 20 years old.

• You experience frequent tripped circuits or blown fuses.
