The importance of matching circuit breaker capacity with conductor's rating

C. Extremely important

Matching the capacity of a circuit breaker with the conductor's rating is extremely important in ensuring electrical safety and preventing potential hazards. The conductor's rating indicates the maximum current that it can safely carry without overheating or causing damage. On the other hand, the circuit breaker's capacity determines the maximum current that it can safely interrupt in case of an overload or short circuit.

By matching the conductor's rating with the circuit breaker's capacity, you ensure that the circuit is properly protected. If the current exceeds the conductor's rating but falls within the circuit breaker's capacity, the breaker will trip and interrupt the circuit to prevent any damage or dangerous situations. However, if the circuit breaker's capacity is lower than the conductor's rating, it may not trip when needed, leading to overheating of the conductor and potential fire hazards.

Therefore, it is crucial to always match the capacity of the circuit breaker with the conductor's rating to maintain electrical safety and prevent accidents. This simple yet essential step can go a long way in protecting your household or workplace from electrical dangers.
