It is limited to a.c. systems supplying equipment below ground at voltages up to and including 1.1 kV, except earth-fault limitation where equipment for use with voltages up to 11 kV is covered. It includes requirements for elements that detect the faulty condition, apparatus for initiating tripping or locking-out of circuit-breaking devices, and equipment for limitation of earth-fault currents.
