Today, protective devices, including fuses, circuit breakers, and relays of various types, are quite sophisticated compared to the ones used 20 years ago. The protective device provides a form of insurance for high-cost electrical equipment. Protection of electrical power systems can reduce the extent and duration of an interruption, as well as reduce equipment damage or personal injury. if a protective device operates, it does so because it reacts to a problem in the system. It is vital then, to investigate the cause and location of the problem; to merely replace the fuse element or reset the protective device does not eliminate the problem. If the cause of the problem cannot be found, contact D-8440 or D-8450 as to possible reasons the protective device operated.
