What is the primary purpose of NFPA 70E in electrical maintenance?

• A. It provides electrical safety guidelines for the workplace, including arc-flash risk assessment, PPE requirements, and safe work practices to prevent shock and arc flash.
• B. It defines the maximum allowable outages per year for workplaces.
• C. It prescribes maintenance scheduling for all electrical equipment based on vendor recommendations.
• D. It sets construction standards for electrical conduits and cabinets.

Answer: (A)

NFPA 70E focuses on electrical safety in the workplace. It provides the framework for identifying and reducing electrical hazards, including performing an arc-flash risk assessment to determine the level of protection needed, specifying the appropriate personal protective equipment, and defining safe work practices and administrative controls to prevent shock and arc-flash injuries. This standard guides how workers interact with energized equipment, requires training, and outlines procedures to maintain a safe operating environment during maintenance and other tasks.

It isn’t about how often outages can occur, nor about scheduling maintenance based on vendor guidelines, nor about construction standards for conduits and cabinets. Those areas are addressed by other codes and standards.
