WebMar 10, 2024 · The 2024 NEC definition of “fault current” and “available fault current,” as well as the informational note and figure in the definition of available fault current help explain the importance of overcurrent protective device interrupting rating and equipment short-circuit current ratings as it relates to the system available fault current. WebSep 30, 2024 · Overcurrent conditions, short circuits, overloads, and overvoltages are some of the basic circuit protection needs of electronic systems. During an overcurrent condition, an excessive current is flowing through a conductor. This can lead to high levels of heat generation and the risk of fire or damage to the equipment.
