In an electric power system, overcurrent or excess current is a situation where a larger than intended electric current exists through a conductor, leading to excessive generation of heat, and the risk of fire or damage to equipment. Possible causes for overcurrent include short circuits, excessive load, and incorrect design. Fuses, circuit breake...
current exceeding the rated currentelectric current exceeding the rated electric current NOTE - For conductors, the rated current is considered as equal to the current-carrying capacity.
a current of a magnitude that is greater than a limiting value, as the value at which a fuse melts.
