Why Does a Breaker Keep Tripping

Why Does a Breaker Keep Tripping?

Electrical breakers are designed to protect your home’s electrical system from overload or short circuits. They act as a safety mechanism that automatically shuts off the power when it detects a problem. If you find that your breaker keeps tripping frequently, it can be frustrating and inconvenient. Understanding the potential causes of a tripping breaker can help you troubleshoot the issue and take appropriate action.

1. Overload: One of the most common reasons for a breaker to trip is an overload. This occurs when too many electrical devices are being used simultaneously, drawing more current than the circuit can handle. For example, running multiple high-powered appliances like air conditioners, heaters, and large appliances on the same circuit can overload it and cause the breaker to trip.

2. Short circuit: A short circuit is another common cause of tripping breakers. It happens when a hot wire touches another hot wire or a neutral wire, resulting in a sudden surge of current. This can occur due to faulty wiring, damaged appliances, or frayed electrical cords. When a short circuit occurs, the breaker trips to prevent overheating and potential fire hazards.

3. Ground fault: A ground fault occurs when a hot wire comes in contact with a ground wire or a grounded metal object, diverting the current from its intended path. This can be caused by damaged insulation on wires or faulty appliances. Ground faults can cause breakers to trip as a safety measure to prevent electrical shock.

4. Outdated or malfunctioning breaker: Breakers can wear out or become faulty over time. If you have an older home with outdated electrical systems or if your breaker is malfunctioning, it may trip more frequently. In such cases, it is recommended to have a professional electrician inspect and replace the breaker if necessary.

5. Circuit overload on a single breaker: Sometimes, a single circuit may have too many electrical devices connected to it, causing the breaker to trip repeatedly. This can happen if the circuit was not designed to handle the load. In such cases, redistributing the electrical devices across multiple circuits or installing a dedicated circuit can help prevent tripping.


1. Can I simply reset the breaker every time it trips?
While resetting the breaker may temporarily restore power, it is essential to identify the underlying cause of the trips. Continuously resetting the breaker without addressing the problem can lead to further damage or pose safety hazards.

2. How do I determine if my breaker is faulty?
If your breaker frequently trips without any apparent reason, it may be faulty. You can hire a professional electrician to inspect and test the breaker to determine if it needs to be replaced.

3. Can I increase the capacity of my breaker to avoid tripping?
No, increasing the breaker’s capacity beyond what the circuit can handle is dangerous and can lead to overheating and potential fire hazards. It is essential to have a qualified electrician assess your electrical system and make any necessary upgrades or repairs.

4. Why does my breaker trip when using certain appliances?
Certain appliances, like high-power kitchen appliances or tools, can draw a significant amount of current. If these appliances are causing the breaker to trip, it could indicate an overload on the circuit. Consider redistributing the load or installing a dedicated circuit for these appliances.

In conclusion, a breaker that keeps tripping can indicate various issues such as overloads, short circuits, ground faults, outdated breakers, or circuit overload on a single breaker. Identifying and addressing the underlying cause is crucial to ensure the safety and proper functioning of your electrical system. If you are unsure or uncomfortable dealing with electrical issues, it is always recommended to seek professional assistance from a qualified electrician.
