OVERCURRENT PROTECTION

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...

Where are overcurrent devices normally installed in a branch circuit. ️: Where the conductors recover their supply. The branch circuit conductor and overcurrent protective device must be sized for the actual non-continuous load plus what percentage of the continuous load. ️: 125% which of the following is true of the voltage rating of a fuse ️: it can be higher than the circuit voltage but never lower when selecting ampere ratings of fuses and circuit breakers the most important co...
