Which statement is most accurate about NFPA 70E Chapter 2 requirements for maintenance of flexible cords and cables?

• A. Cords and cables shall not have worn, frayed, or damaged areas
• B. Cords can have minor damaged areas
• C. Cords and cables should be replaced monthly
• D. Cords can be used when worn

Answer: (A)

Flexible cords and cables must be kept in safe condition; there shall be no worn, frayed, or damaged areas. Damaged insulation can expose energized conductors, which raises the risks of electric shock, short circuits, and arc flash. Because of that, any cord showing wear or damage should be taken out of service and replaced, or repaired only by a qualified person, in a way that restores safe insulation and enclosure. Routine inspection before use is essential, and there is no allowance for using cords that are worn or damaged. Monthly replacement or using worn cords would introduce avoidable hazards, so the standard emphasizes keeping cords in pristine condition to prevent harm.
