Why and How to Fix Circuit Breakers Keep Tripping?

2023/05/25 丨Technical

Circuit breakers are an essential part of electrical systems in homes and businesses. They help prevent electrical fires and other hazards by interrupting the flow of electricity when a fault is detected. At the same time, they protect the home or office building from overloads, short circuits, and other problems that could damage the electrical system.


Possible Causes of Circuit Breakers Tripping


  • Overload: Circuit overloading is the most common cause of circuit breaker tripping. A circuit overload occurs when multiple electrical devices are connected to a single circuit, causing the circuit to draw more current than it can handle.

  • Short Circuit: A short circuit occurs when the hot wire touches the neutral or ground conductor, creating a direct path for current to flow. This can cause a sudden surge of current that can cause the circuit breaker to trip.

  • Ground Fault: A ground fault occurs when the hot wire touches the ground wire or a grounded metal object. However, ground faults are particularly dangerous and can cause an electric shock or fire.

  • Old or Defective Circuit Breakers: Circuit breakers can wear out or malfunction when after heavy use which will cause them to trip frequently.


How to Fix Circuit Breakers Tripping


Identify the Problem


First, you must determine why the circuit breaker tripped. A circuit breaker that keeps tripping may be due to an overload, a short circuit, a ground fault, an old electrical system, or a defective circuit breaker. After determining any of the above causes, make a note of when the circuit breaker tripped and what circuit it was connected to.


Check for Overload


Probably the most common cause of a tripped circuit breaker is an overloaded circuit. So we can disconnect some equipment that is not necessarily connected to the circuit. This way we can reduce the electrical load and prevent the circuit breaker from tripping.


Check for Wiring Problems


Faulty or loose wiring connections can also cause the circuit breaker to trip. Check the circuit wiring for damage or fraying. If you notice loose connections, it is best to turn off the power and contact a technician.


Test Circuit


After you have determined why the circuit breaker tripped and taken all the necessary steps to correct the problem, it's important to test the circuit to make sure it's working properly. To do this, turn off the affected circuit and reset the circuit breaker. Then turn the circuit and electrical equipment back on for testing.


Upgrading Electrical System


If the circuit breaker trips frequently, it is also possible that the electrical system is outdated or insufficient to meet your power needs. In this case, the electrical system must be upgraded to ensure normal operation of circuit breakers and electrical equipment.




In summary, overloads, wiring problems, loose connections, and ground faults are common causes of circuit breakers tripping repeatedly. To repair a circuit breaker that keeps tripping, you need to determine the cause of the problem, disconnect and unplug equipment, check for loose connections, test the circuit, and upgrade the electrical system if necessary. If you are unsure how to repair a circuit breaker that keeps tripping, contact a local professional technician if necessary to help you safely and effectively identify and fix the problem.
