National Electrical Installation Standards

Standards as High as Your Own

Friday, March 18, 2022



We were recently doing a service upgrade (changing out a panelboard) and the inspector said we have to shut the power off. What NEC Section requires this? We think the inspector has requested something beyond the responsibilities of his position. What say you?

Hi Allen,

The NEC does not address working on energized equipment or creating electrically safe work conditions. This information on electrical safety in the workplace is found in OSHA Regulations 1910 Subpart S and 1926 Subpart K) and addressed more specifically in NFPA 70E-2021, the Standard for Electrical Safety in the Workplace. The requirements to eliminate the electrical hazards and establish electrically safe work conditions are provided in NFPA 70E-2021 Sections 110.1 through 110.4. Another good bit of information is found in the definition of qualified person in Article 100 of NFPA 70E.

Hope this is useful.
