Tripping Breakers and Power Loss

Circuit breakers are vital safety devices that protect your property from electrical damage by cutting off power when issues occur. If you find yourself dealing with frequent breaker trips or power loss, it's a clear indication of a serious problem. A common cause is an overloaded circuit, which happens when too many high-amp appliances are connected to a single circuit. This overload can trip the breaker, shutting off power to prevent overheating and potential electrical fires.



RCDs (Residual Current Devices) also frequently cause breaker trips, making up a significant portion of incidents in the electrical field. These devices are set to detect imbalances in electrical current and cut off power to prevent electric shock or fire. If your RCD keeps tripping, it could be due to a faulty appliance, damaged wiring, or moisture in the electrical system. Such issues require professional electrical repairs in Paraparaumu.


To help identify the cause of a tripping breaker, first, turn off and unplug all appliances in the affected circuit. Then, locate the circuit breaker and try to reset it. If power remains stable, the problem might be with one of the appliances. However, if the breaker trips again immediately, it could indicate a wiring issue, requiring a qualified electrician in Kapiti's expertise.


Breaker tripping can also stem from short circuits, ground faults, or an outdated electrical system struggling to support modern appliances. In such cases, it's essential to consult a Registered Master Electrician. They can diagnose the issue and perform the necessary repairs in Paraparaumu, ensuring your electrical system's safety and reliability. Ignoring frequent breaker trips or power loss can be dangerous, potentially leading to property damage or electrical fires if not addressed.
