Top Reasons Your Circuit Breaker Keeps Tripping

A circuit breaker is designed to protect your home’s electrical system by shutting off power when it detects a problem. While it’s normal for a breaker to trip occasionally, frequent trips can signal underlying issues that shouldn’t be ignored. At Benchmark Electrical, we explain why your circuit breaker keeps tripping and how to address them safely.

Overloaded Circuit

An overloaded circuit is one of the most common reasons for a tripped breaker. This happens when too many devices or appliances are connected to a single circuit, exceeding capacity.

Signs of an Overloaded Circuit:

• Frequent trips when multiple devices are used simultaneously.
• Dimming lights or flickering when appliances are turned on.

Solution:

Distribute your devices across multiple outlets or circuits. If the problem persists, consider upgrading your electrical panel or adding more circuits to handle the load.

Short Circuit

A short circuit occurs when a live wire touches another live or neutral wire, causing a surge of electricity that trips the breaker. This can result from faulty wiring, damaged appliances, or exposed wires.

Warning Signs:

• Burnt or metallic smell near outlets or switches.
• Blackened or scorched outlets.

Solution:

Short circuits can be dangerous. If you suspect one, turn off the power and contact Benchmark Electrical immediately.

Ground Fault

A ground fault happens when a live wire comes into contact with a grounded surface, such as a metal outlet box or appliance casing. This can pose a serious safety hazard, especially in areas like kitchens and bathrooms where water is present.

Warning Signs:

• Frequent trips in circuits connected to outdoor or wet areas.
• A slight shock or tingling sensation when touching appliances.

Solution:

A Residual Current Device (RCD) protects circuits in wet or outdoor areas. If you already have RCDs tripping, they may need repair or replacement.

Faulty Appliances

An appliance with damaged wiring or internal components can draw more current than usual, tripping the breaker.

Signs of a Faulty Appliance:

• The breaker trips whenever a specific appliance is turned on.
• Visible damage or frayed cords on the appliance.

Solution:

Unplug the appliance and test the circuit with other devices. If the breaker stops tripping, repair or replace the faulty appliance.

Arc Fault

Arc faults occur when there’s a loose connection or damaged wire, causing an electrical arc that trips the breaker. Arc faults can lead to fires if not addressed.

Warning Signs:

• The breakers are tripping without an apparent cause.
• Buzzing or crackling sounds near outlets.

Solution:

If you suspect an arc fault, call an experienced electrician to find the fault. Arc faults are extremely dangerous. Arc Fault Detection Devices (AFDDs) are also available. However, they are a relatively new technology in Australia that helps prevent electrical fires by automatically cutting power when they detect an arc fault.

Outdated Electrical System

If your home’s electrical system is outdated, it may not be able to handle the demands of modern appliances and devices. This can lead to frequent trips as circuits struggle to keep up.

Signs of an Outdated System:

• Frequent breaker trips across multiple circuits.
• Limited outlets and reliance on extension cords.

Solution:

Consider upgrading your electrical panel or rewiring your home to meet modern standards. Benchmark Electrical can assess your system and recommend the best solutions.

The Breaker Itself is Faulty

Sometimes, the problem lies with the breaker itself. Over time, circuit breakers can wear out and fail to function correctly, leading to frequent or random trips.

Solution:

If all other possibilities have been ruled out, a faulty breaker may need to be replaced. This is a straightforward job for a licensed electrician.

When to Call a Professional

While some circuit breaker issues can be resolved with simple fixes, others require the expertise of a licensed electrician. If your breaker keeps tripping despite troubleshooting, it’s time to call in the professionals.
