Safe operating procedures for energized repair work.Safe operating procedures for energized diagnostic work.Safe operating procedures using boundaries, barriers, and PPE.Responsibilities required under this policy.Electrical power sources shall be de-energized and verified prior to working on electrical equipment except when de-energization creates a greater hazard and a properly executed and approved Energized Electrical Work Permit (EWP) has been completed.Ģ.2 This policy outlines the minimum guidelines for: Power generation, transmission, and distribution typically ends at the service point, service entry, or the service meter of the building or premises.Ģ.1 NC State’s goal is to minimize employee exposure to shock and arc flash hazards that can occur during the installation, repair, maintenance, and operation of electrical equipment, components, and systems. This policy does not apply to work performed at NC State on power generation, transmission, and distribution systems designed in accordance with the Institute of Electrical and Electronics Engineers (IEEE) National Electrical Safety Code (NESC®). Premises systems typically begin at the service point, service entry, or the service meter. This policy applies to work performed at NC State on equipment associated with premises systems, which is designed in accordance with the National Fire Protection Association standard NFPA 70, National Electrical Code (NEC®). The electrical system at the university is a complex network of power generation, distribution, and premises systems. Provide guidelines and procedures for working on energized equipment and systems, including testing, troubleshooting, and voltage measurement. Users of plug and cord electrical equipment.
