1.0.1.4 Enforcement (p.3) (a) This code is intended for mandatory application by government bodies exercising legal jurisdiction over electrical installation. The enforcement of the PEC is the responsibility of the authority having jurisdiction (AHJ), who is responsible for interpreting requirements, approving equipment and materials, waiving Code requirements, and ensuring that equipment is installed in accordance with listing instructions. 8

1.0.1.4 Enforcement Approval of Equipment and Materials. Only the authority having jurisdiction has authority to approve the installation of equipment and materials. Typically, the authority having jurisdiction will approve equipment listed by a product testing organization, but the PEC doesn’t require all equipment to be listed. 9

1.0.1.7 Examination of Equipment Safety (p.4) Product evaluation for safety is typically performed by a testing laboratory, which publishes a list of equipment that meets a nationally recognized test standard. Products and materials listed, labeled, or identified by a testing laboratory are generally approved by the authority having jurisdiction. 10
