For the installation and use of electrical equipment under NEC, consent must be obtained from whom?

In the context of the National Electrical Code (NEC), obtaining consent is specifically directed towards the Authority Having Jurisdiction (AHJ). The AHJ is typically a local regulatory body or inspector that enforces compliance with the electrical code and other safety standards. They are responsible for ensuring that electrical installations meet established regulations, ordinances, and standards to promote safety and reliability in electrical systems.

The AHJ's role is critical because they have the expertise to evaluate electrical installations and ensure that they comply with the NEC. This helps to prevent safety hazards and ensures that electrical systems are safe for public use. They also have the authority to grant permits for electrical work and to conduct inspections to verify compliance.

While local government bodies may be involved in broader regulatory or licensing processes, it is the AHJ specifically that oversees electrical installations and ensures that they meet the necessary safety and regulatory standards as outlined in the NEC. Electric utility companies and manufacturers do have roles in the electrical system, but they do not grant consent for installation in the same regulatory capacity as the AHJ.
