Who is responsible for the approval of electrical installations and systems?

The authority having jurisdiction (AHJ) plays a critical role in approving electrical installations and systems. The AHJ is typically a government or regulatory body that ensures compliance with applicable codes, standards, and regulations. Their responsibility includes reviewing plans, conducting inspections, and verifying that installations meet safety requirements.

Approval from the AHJ is essential because it signifies that the work complies with local, state, or national electrical codes, which are designed to protect public safety. This oversight helps to ensure that all electrical installations are safe and functional, reducing the risk of electrical hazards.

Other individuals, such as the electrical contractor or project manager, may execute or coordinate the work involved in electrical installations, but they do not have the authority to approve or validate compliance with electrical standards. The building owner is generally interested in the overall compliance and safety of their property but is not directly involved in the approval process of electrical installations.
