ICC Residential Electrical Inspectors Practice Exam

When a new service panel is connected, what is the required inspection for the connections?

1. Visual inspection only

2. Combination inspection

3. Rough-in inspection

4. Final inspection

The correct answer is: Combination inspection

When a new service panel is connected, a combination inspection is required to ensure the safety and compliance of the electrical installation. This type of inspection typically involves looking at multiple aspects of the electrical system at once. During a combination inspection, the inspector evaluates both rough-in work and the final connections, checking that all elements of the electrical system meet current codes and standards. This includes verifying proper wire connections, grounding, and the overall integrity of the panel and its components. By conducting a combination inspection, the inspector ensures that the service panel is installed correctly and safely, which is crucial for the overall functionality and safety of the electrical system in the building. Choosing a combination inspection over a visual inspection alone or any other type ensures that comprehensive checks are made, minimizing the risk of electrical hazards and enhancing the reliability of the new electrical service.
