What is the process called that ensures electrical installations meet code requirements?

• A. Inspection and Approval
• B. Testing and Certification
• C. Design Review
• D. Commissioning

Answer: (A)

The process is inspection and approval. After design and permitting, the installation is examined on-site by the authority having jurisdiction (AHJ) to verify that wiring methods, materials, overcurrent protection, clearances, labeling, grounding, and workmanship meet the applicable electrical code and local amendments. Only after passing these inspections does the AHJ issue final approval or a certificate of compliance, allowing the system to be energized. This formal review ensures safety and code compliance before any operation.

Other options don’t fit as the formal, code-verifying step the AHJ performs before energization: commissioning focuses on performance and start-up, and design review or testing/certification can occur at different stages but do not by themselves authorize entry or energization.
