Why is the circuit breaker tripping?

Why is the circuit breaker tripping and how to reset it?

The reasons for a circuit breaker tripping can vary and may include everything from temporary disturbances to more serious electrical faults. The circuit breaker plays a crucial role in your electrical system by protecting against both equipment damage and personal injury.

To reset a circuit breaker:

Try to Reset the Breaker: Begin by attempting to reset the breaker by flipping the switch back up. If the breaker trips again shortly after resetting, it indicates that there may be a ground fault or neutral fault in your property. This happens when either the live or neutral wire makes contact with the ground.
Troubleshooting a Ground Fault: There are several steps you can take to troubleshoot a ground fault.

Importance of a Circuit Breaker:

Having a circuit breaker installed in your electrical panel is crucial due to its function: to immediately cut off power in the event of a ground fault, which applies to both your electrical system and the devices connected to it. Installing a circuit breaker is now a mandatory requirement for all new homes, and we strongly recommend adding one to existing homes where it is not already installed.

Recommendations:

Install a Circuit Breaker: If your existing circuit breaker is old, we recommend replacing it.
Professional Installation: Installing a circuit breaker in your electrical panel requires a licensed electrical company connected to the Electrical Safety Authority. Only authorized electrical companies, such as Dutypartner, are permitted to perform permanent electrical installations.

5 reasons why a circuit breaker might trip:

If your circuit breaker trips occasionally, the most common cause is usually an electrically connected appliance, often one that is also connected to water, such as a dishwasher or washing machine. These appliances may have become damaged or are old. If your circuit breaker trips when you plug in an appliance, troubleshooting is straightforward; remember which appliance you plugged in before the breaker tripped.
In cases of damaged insulation, leakage currents can escape into other conductors and create a ground fault. This can be due to improper installation or lack of protection for the cable in its environment.
Outdoor appliances are a common factor in ground faults and tripping circuit breakers. Often, after heavy rain, water may have seeped into an outlet or fixture.
Another common reason for occasional tripping is your water heater or heat pump. The heating element in your water heater may have failed, creating a ground fault after the metal has expanded enough to allow water to seep in.
Lastly, the circuit breaker itself may be faulty. It could have become too old and trips due to increased sensitivity.

Circuit Breaker Trips During Rain

If a circuit breaker trips during rain, it can become a complex troubleshooting task if you have multiple outdoor appliances such as outlets, fixtures, or electrically connected devices. We recommend trying to cut off power to all outdoor appliances by removing the plug or turning off the circuit breaker. If you identify the fault, we advise contacting an electrician, such as Dutypartner, or calling 0722 400 450 to address the issue.

If the circuit breaker trips when you plug in a specific plug or turn on a particular circuit breaker, it indicates that the problem lies within the part of the electrical system protected by that plug or breaker. To address this, first remove the plug or turn off the circuit breaker and then reset the circuit breaker.
