Under NFPA 70E, when is it permissible to perform work on energized equipment, and what permit is typically required?

• A. Only when de-energizing would create greater hazards and a qualified person has determined it cannot be avoided; an energized work permit is required.
• B. Whenever a supervisor approves, no permit required.
• C. When the equipment is new, no permit required.
• D. Only for testing, no permit required.

Answer: (C)

Under NFPA 70E, work on energized equipment is allowed only as a controlled exception when de-energizing would create greater hazards and a qualified person determines the work cannot be performed safely while it’s de-energized. In that situation, an energized electrical work permit must be in place before starting, outlining the hazards, required PPE, protective boundaries, and procedures. New equipment does not waive this requirement, and supervisor approval alone does not substitute for the permit. The permit process ensures proper planning and protection whenever energized work is necessary.
