Which two ampere ratings are typically found on a circuit breaker?

The correct answer highlights the important classifications for understanding how circuit breakers operate. Continuous rating refers to the maximum current that a circuit breaker can carry over an indefinite period without tripping. This rating ensures that the circuit breaker can handle the normal operating load of the circuit it protects without overheating or malfunctioning.

Interrupting rating, on the other hand, indicates the maximum current that the breaker can safely interrupt or disconnect during a fault condition, such as a short circuit. This rating is crucial for ensuring that the breaker can effectively protect the circuit by preventing damage to wiring and equipment and minimizing the risk of fire.

Understanding these two ratings is essential for selecting the right circuit breaker for specific applications. It ensures that the breaker will function correctly during both normal and fault conditions, providing reliable protection for electrical systems.
