Which of the following is NOT a responsibility of an electrical inspector?

An electrical inspector's primary role is to ensure that electrical installations comply with relevant codes and standards. This includes conducting inspections during and after installation, as well as verifying that equipment and systems function correctly and safely. Conducting tests for equipment performance, ensuring compliance with regulations, and overseeing installation processes are all integral to their responsibilities.

On the other hand, advising on design improvements typically falls outside the purview of an electrical inspector. While they may identify issues or areas for concern during their inspections, their primary role is not to participate in the design process or make recommendations for design alterations. This focus on compliance and safety rather than design consultation delineates the scope of an electrical inspector's responsibilities.
