Why Does a Breaker Keep Tripping?

A frequently tripping circuit breaker can pose a frustrating and potentially dangerous problem in a home.

A frequently tripping circuit breaker can pose a frustrating and potentially dangerous problem in a home. Understanding the underlying causes of this issue is essential to finding a solution. Keep reading to learn more about the common reasons why circuit breakers trip.

Circuit overload

Circuit breakers often trip due to overloading, which occurs when a circuit exceeds its maximum electrical load. This is a crucial safety mechanism, as overloading a circuit can cause overheating and create a potential fire hazard. The excess heat generated by the overloaded circuit causes the breaker to trip, preventing further electrical flow.

To avoid overloading circuits, distribute electrical loads evenly across all circuits, and don't plug high-wattage devices into the same circuit. Also, consider installing additional circuits if necessary.

Short circuit

A short circuit occurs when the hot and neutral wires in a circuit touch, creating a path of low resistance that allows a large amount of current to flow. This sudden surge of electricity can cause the circuit breaker to trip.

Damaged wiring, loose connections, or faulty appliances can cause short circuits. They can also produce sparks or smoke and pose a significant fire hazard. Suppose a short circuit is suspected of tripping the breaker. In that case, it's essential to turn off the power to the circuit and seek professional assistance from a licensed electrician.

Aging electrical system

As electrical systems age, the wiring and connections can deteriorate or become frayed, leading to a higher risk of short circuits and overloaded circuits. This can cause breakers to trip more frequently as the electrical system struggles to handle the demands of modern appliances and devices.

In addition, outdated electrical systems may not meet current safety standards, increasing the risk of electrical fires or shock hazards. Upgrading the electrical system is also necessary to improve safety and efficiency.

Ground fault

A ground fault occurs when an electrical current escapes the circuit and travels through an unintended path to the ground. This can lead to a dramatic current surge and cause the circuit breaker to trip as a safety precaution. Damaged wiring, faulty appliances, or electrical system moisture can cause ground faults.

Ground faults can pose a risk of electrical shock and create a potential fire hazard. This is why GFCI (Ground Fault Circuit Interrupter) outlets are crucial in new homes for extra protection, especially in areas near water sources, such as kitchens, bathrooms, and basements. They can rapidly cut power to the circuit when ground faults are detected.

When to call a technician

If you experience any of the electrical issues listed above, it's crucial to call a licensed technician. Frequent breaker trips, flickering or dimming lights, buzzing or humming sounds coming from outlets or switches, burning smells or smoke, and hot outlets or switches can all indicate underlying electrical problems.

Attempting to fix these issues on your own can be dangerous and lead to further problems, such as electrical shock or fire. On the other hand, a licensed technician has the training and expertise to identify and repair electrical issues safely and effectively.
