Electrical preventive maintenance and testing is one of the most important aspects to assuring the reliability and integrity of electrical distribution systems and equipment.It is also important for the protection of employees,or people in general.However,preventive maintenance of electrical systems and equipment,specifically with regard to overcurrent protective devices,is often overlooked or performed infrequently.This paper will explore:Guides for electrical equipment and low-voltage overcurrent protective device maintenance and testing.Analysis of various electrical equipment installations and the maintenance program for low-voltage overcurrent protective devices practiced.Failure statistics for low-voltage overcurrent protective devicesThe reliability and integrity of low-voltage overcurrent protective devices.Arc flash hazards with respect to preventive maintenance of low-voltage overcurrent protective devices.Frequency of Maintenance Considerations for low-voltage circuit breakers.
