Final answer:
A circuit breaker or fuse has two ampere ratings: continuous and instantaneous ratings.
Step-by-step explanation:
On a circuit breaker or fuse, you would find two ampere ratings: Continuous and instantaneous ratings.
The continuous rating indicates the maximum current that the circuit breaker or fuse can handle continuously without tripping or blowing. It represents the maximum safe operating current for the circuit.
The instantaneous rating represents the maximum current that the circuit breaker or fuse can handle for a very short period of time, such as during a power surge or a short circuit. It is higher than the continuous rating and allows for temporary overloads.
