The current-carrying capacity of an overcurrent protective device. The fuse or circuit breaker is subjected to a current above its ampere rating; it will open the circuit after a predetermined period of time. ️: Ampere rating Choose the correct statement. A short circuit results from placing too many loads on a circuit. An overload current can be caused by worn motor bearings. Sustained overloads will not damage equipment or conductors as long as they do not exceed 125% of normal cur...
