Why Does My Circuit Breaker Keep Tripping?

If your circuit breaker keeps tripping, you’re not alone — it’s one of the most common calls we get at Top Notch Electrical.

A circuit breaker is designed to protect your home by automatically shutting off power when it detects a fault. But when it trips repeatedly, something is wrong — and ignoring it can be dangerous.

The 3 Most Common Causes

Overloaded Circuit

This is the most frequent culprit. Every circuit in your home has a limit. When too many appliances run at once — heaters, kettles, air conditioners — the circuit draws more current than it can handle and the breaker trips to prevent overheating. The fix is usually redistributing your appliances across different circuits.

Short Circuit

A short circuit is more serious. It happens when a live wire touches a neutral wire — often due to damaged insulation, a faulty appliance, or loose wiring. Short circuits can cause sparks or even fires. If your breaker trips immediately when you reset it, a short circuit could be the reason. Don’t keep resetting — call a licensed electrician.

Ground Fault

Similar to a short circuit, a ground fault occurs when a live wire contacts a grounded part of your system. These are especially common in bathrooms, kitchens, and outdoor areas where moisture is present. A ground fault can cause electric shock — which is why safety switches and RCDs are so important in Australian homes.

When Should You Call an Electrician?

If your breaker trips once after an obvious overload (like running too many appliances), you can reset it yourself. But if it keeps tripping, trips as soon as you reset it, or you notice burning smells, flickering lights, or scorch marks near your switchboard — stop and call a licensed electrician immediately. These are warning signs of a potentially serious fault.
