An overcurrent event occurs when the normal current-carrying capacity of a circuit is exceeded. Ground faults, overloads, and short circuits are types of overcurrent events. A partial or total failure of a circuit load can cause load-generated overcurrent. The failure lowers the total resistance in the circuit, allowing more current to flow. A familiar example is a stalled motor, which gets hot because of excessive power draw, resulting in damaged insulation on the motor windings that allows adjacent wires to touch. This causes a short circuit. Other examples of overcurrent events are shorted batteries or faulty power supplies.
