Which is the responsibility of the authority having jurisdiction (AHJ)?

The role of the authority having jurisdiction (AHJ) primarily revolves around the interpretation and enforcement of codes and standards, including the National Electrical Code (NEC). This responsibility is critical because it ensures that electrical installations comply with safety guidelines, thus protecting both the public and the professionals working in the field. The AHJ reviews plans, conducts inspections, and determines whether the work is being done according to the established rules.

By interpreting NEC rules, the AHJ also ensures that any local amendments or specific project requirements are adhered to, which may not be explicitly covered by the NEC. This ability to interpret and enforce codes allows them to play an essential part in maintaining safety across electrical installations. Their role does not typically involve providing training for electricians, supplying materials, or supervising financial aspects of projects, as those responsibilities fall outside the scope of code enforcement and safety regulation.
