When inspecting electrical systems, which of the following must an inspector report as deficient?

The presence of operable smoke detectors is essential for the safety of a home, but they do not constitute a deficiency in the electrical system itself. Instead, the inspector's focus should be on the functionality and safety of the electrical wiring and connections.

Inadequate wiring connections represent a clear hazard as they can lead to overheating, arcing, or electrical fires, indicating that this is a deficiency that needs to be reported. The effectiveness of the grounding system is also crucial; it ensures that excess electricity can safely dissipate into the ground, preventing electrical shock and equipment failure.

While operable fire detectors are important for safety, they fall under a different category of safety features related to fire prevention rather than being solely an electrical system deficiency. Overall, inadequate wiring connections and grounding system effectiveness are critical areas that must be reported as deficiencies, ensuring compliance with safety standards and protecting the home's occupants.
