Circuit Breaker Trips: Common Causes and Simple Solution

causes of circuit breaker trips and solutions

Circuit breakers are an important part of any electrical system. Whether in our homes or offices, these devices protect us from electrical overloads, short circuits, and other electrical faults. However, sometimes circuit breakers can trip unexpectedly, cutting off power to a given area and causing inconvenience. 

Understanding the common causes behind circuit breaker trips and learning simple solutions to address them can help us avoid frequent disruptions. In this article, we will explore the various factors that can lead to circuit breaker trips and provide simple solutions to mitigate these issues effectively.

What is a Breaker Trip?

Ever wondered what happens when your lights suddenly go out, or your appliances stop working? Chances are, it’s due to a circuit breaker trip.

Circuit breakers are designed to protect electrical wiring and appliances from potential damage due to an overload or short circuit. When the electrical current going through a given circuit exceeds its safe limit, the breaker trips, cutting off power to that circuit and preventing further damage. This is why, when a breaker trips, all of the electrical devices connected to that circuit stop working.

Common Causes & Solutions of Circuit Breaker Trips

There are several common causes of breaker trips, including:

1. The Circuit is Overloaded

One of the most common causes of breaker trips is an overloaded circuit. This occurs when the electrical load on a circuit exceeds its maximum capacity.

Every circuit has a specific amperage rating, which represents the amount of current it can safely handle. When a circuit draws more current than it can handle, the breaker trips to prevent overheating and potential fire hazards.

Overloading a circuit can happen in various ways. For instance, plugging too many high-wattage appliances into a single outlet or connecting multiple power-hungry devices to a single circuit can easily overload it. Additionally, excessively using extension cords or power strips can lead to a trip.

To resolve this issue, it is important to avoid overloading circuits by plugging in fewer appliances or switching to a circuit with a higher capacity. Additionally, using power strips and extension cords should be done sparingly, if at all.

2. Short Circuits

Another common cause of breaker trips is a short circuit. A short circuit occurs when the hot and neutral wires of a circuit come into contact with one another. This creates a large amount of current, which can cause significant damage to the wiring, connected devices, and appliances.

It’s best to contact an electrician near you to help diagnose and repair any short circuit issues. Short circuits should never be handled by someone who is not trained in electrical wiring safety procedures.

3. Ground Faults and Electrocution Hazards

Ground faults occur when electrical current is discharged to the ground in an unintended manner – due to damaged insulation or other wiring faults. This creates an unintended path for current to flow to the ground, bypassing the intended circuit.

In case of a suspected ground fault, immediately switch off the main power supply and contact a qualified electrician. Do not attempt any repairs yourself, as this could result in further damage or injury.

4. Aging or Faulty Circuit Breakers

Aging or faulty circuit breakers can also be a cause of frequent trips. Over time, circuit breakers may become less reliable due to wear and tear or internal malfunctions. These issues can lead to false trips or failure to trip when necessary, compromising the safety of the electrical system.

If you suspect an issue with your circuit breaker, it’s important to have it inspected by a professional electrician. They can perform tests to assess its functionality and determine if a replacement is necessary.

Testing and Maintaining Circuit Breakers

Testing and maintaining circuit breakers is crucial for ensuring their optimal performance and preventing unexpected trips. Here are a few important practices to consider:

Regular Testing

Periodically testing your circuit breakers can help identify any potential issues before they lead to trips or malfunctions. Follow the manufacturer’s instructions or consult a professional electrician for guidance on how to perform the test correctly.

Cleaning the Circuit Breaker

Dust, debris, and corrosion can affect the proper functioning of circuit breakers. That’s why it’s recommended that you clean your breaker panel at least once a year. This can be done with a vacuum cleaner, compressed air, and other cleaning tools. Just make sure to use caution and adhere to the manufacturer’s safety instructions.

Replacing Aging Circuit Breakers

If your circuit breakers are a few decades old, it might be time to replace them. Newer models often offer greater reliability and improved safety features that can help reduce the risk of unexpected trips or surges. A professional electrician can help you select and install the right circuit breaker for your needs.


As you can see, there are various steps you can take to maintain and test your circuit breakers properly. From cleaning the breaker panel to testing for functionality, it’s important to stay on top of these maintenance tasks in order to ensure optimal performance and safety.
