What is one effect of exceeding the interrupting rating of a fuse or circuit breaker?

Exceeding the interrupting rating of a fuse or circuit breaker can lead to a potential failure of the device. The interrupting rating is the maximum amount of fault current that a protective device can safely interrupt without being damaged or posing a safety hazard. When the fault current exceeds this rating, the device may not be able to open the circuit effectively. This can result in the fuse blowing uncontrollably or the circuit breaker failing to trip, causing damage to the electrical system and creating safety risks such as electrical fires, shock hazards, or equipment damage. Therefore, ensuring that fuses and circuit breakers are selected with an appropriate interrupting rating is crucial for the safety and reliability of the electrical system.
