In NEC terminology, what is the Authority Having Jurisdiction?

• A. The entity responsible for enforcing the NEC and interpreting its rules
• B. A voluntary guideline adopted by electrical inspectors
• C. The manufacturing standard for equipment
• D. The local utility company

Answer: (A)

Authority Having Jurisdiction is the person or organization charged with enforcing the NEC and interpreting its rules for a specific area. This is usually the local building department or electrical code official, such as a city electrical inspector or fire marshal. They issue permits, conduct inspections, and decide whether a installation meets the code, including how to apply ambiguous provisions. The NEC is a model code, and enforcement or any jurisdictional amendments come from the AHJ. The other options don’t fit because a voluntary guideline isn’t enforceable, the NEC isn’t a manufacturing standard for equipment, and the local utility company is concerned with power supply and service, not code enforcement or interpretation.
