This recommended practice provides short-circuit current information including calculated short-circuit current duties for the application in industrial plants and commercial buildings, at all power system voltages, of power system equipment that senses, carries, or interrupts short-circuit currents. Equipment coverage includes, but should not be limited to, protective device sensors such as series trips and relays, passive equipment that may carry short circuit current such as bus, cable, reactors, and transformers as well as interrupters such as circuit breakers and fuses. For the Electrical Engineer in an industrial or a Commercial application environment, the IEE 3000 Standards Collection for Industrial & Commercial Power Systems, formerly the Color Books, are presently the most comprehensive collection of recommended practices available. The IEE Color Books are developed and revised by the technical committees of the IEE Industry Applications Society (IAS) Industrial and Commercial Power Systems (I&CPS) Department.
