This Standard specifies basic requirements on maintenance of electrical systems based on principles of loss control and safety management systems. It also provides guidance on the selection of reference standards, equipment-specific maintenance procedures, and the assessment of electrical equipment to verify correct function. This Standard applies to new and existing electrical equipment. For new installations of electrical equipment, this Standard can be applied during the early design stages to allow for the implementation of proactive electrical maintenance practices and maintenance safety. The purpose of this Standard is to facilitate the safe, reliable, and cost-effective operation of electrical equipment and systems through the application of consistent maintenance practices. The requirements of this Standard are intended to address worker and public safety as a primary objective and the protection of property and the environment as secondary objectives.
