Which of the following systems is an inspector NOT required to operate during an inspection?

An inspector is not required to operate systems and components that are shut down or otherwise inoperable during an inspection. This is because evaluating the functionality of such systems is not possible when they are not in a working condition. If a system is not operating, the inspector cannot properly assess its performance or identify any potential issues.

In contrast, the inspector is typically expected to evaluate automatic safety controls, shut-off valves, and manual stop valves, as these items are generally within the normal scope of an inspection. Inspectors must ensure that these components are functioning correctly and that they can effectively manage safety in the system they are inspecting.

By focusing on systems that are operational, inspectors can provide valuable insights into the condition and safety of a home, whereas evaluating non-operational components would not yield useful information for the homeowner or potential buyers.
