Textbook Question
Chapter 28, Problem 13R
All electrical components have some sort of “withstand rating.” The NEC and UL Standards refer to this as the component’s short-circuit current rating. This rating indicates the ability of the component to withstand a specified amount of fault current for the time it takes the overcurrent device upstream of the component to open the circuit. NEC _____ refers to short-circuit current rating.
