Correct Answer:

Authority Having Jurisdiction; enforces code through permits and inspections.

Explanation:

Authority Having Jurisdiction stands for AHJ. The AHJ is the official entity empowered by law to enforce the electrical code in a given area. Its role includes reviewing plans when required, issuing electrical permits, and conducting or arranging inspections at various stages of a project to ensure the installation meets the code. The AHJ determines compliance, can require corrections, and may take enforcement actions such as stop-work orders or fines if requirements aren’t met. In practice, the AHJ is usually the local building department or electrical inspector, though responsibilities can involve fire safety authorities or state agencies depending on the jurisdiction.
