While they are designed to be durable and long-lasting, they are not immune to the effects of wear and tear. Several factors can contribute to the degradation of a circuit breaker: Age: Over time, the internal components of a circuit breaker can deteriorate, leading to decreased effectiveness and reliability.
Circuit breaker plays an important role in the safety of our daily life because it protects electrical equipment and devices against short circuit and overload faults. The normal life of a standard circuit breaker is up to forty years. However, sometimes faults occur and a breaker goes bad.
However, this unanticipated operation does not ensure the circuit’s protection. Moreover, despite being operational, a malfunctioning circuit breaker cannot guarantee the anticipated safeguarding of the circuit. Often, once the circuit breaker deteriorates, it ceases to provide power, resulting in a loss of power to the circuit.
Frequent Tripping: If a circuit breaker trips often due to frequent power surges or overloads, it can accelerate the wear on its internal mechanisms. Constant tripping can cause damage to the internal components and decrease the lifespan of the breaker.
Poor Maintenance: Lack of proper maintenance or neglecting to address electrical issues promptly can lead to the deterioration of the circuit breaker. When a circuit breaker wears out, it may become less reliable in tripping during overloads or short circuits, potentially compromising the safety of your electrical system.
Electrical Fluctuations: In some cases, fluctuations in the electrical supply during the outage or restoration period can impact the circuit breaker’s functionality, especially if the electrical system is older or already vulnerable. To protect your electrical system during a power outage and subsequent restoration, it’s advisable to:
