What is the primary purpose of NFPA 70E in low-voltage electrical work?

• A. To design higher voltage transmission lines.
• B. To regulate building insulation standards.
• C. To protect workers from electrical hazards by specifying safe work practices, PPE requirements, and hazard assessment procedures.
• D. To set energy efficiency targets for electrical equipment.

Answer: (C)

NFPA 70E is about protecting workers from electrical hazards in the workplace. It lays out safe work practices, PPE requirements, and the procedures used to assess hazards (arc flash analysis) so workers can choose the right protective measures before and during electrical tasks. The standard guides how to plan, train, and execute work safely around electrical equipment, helping reduce shock, arc flash, and related injuries.

This isn’t about designing transmission lines, insulating materials for buildings, or setting energy efficiency targets. Those areas are addressed by other codes and standards.
