What should be inserted into an electrical panel during an inspection?

During an electrical panel inspection, it is generally recommended to use visual observation and manual inspection techniques rather than inserting tools. While tools like voltage meters and circuit testers are beneficial for diagnosing or testing systems, they are not typically inserted into an electrical panel during a standard inspection. The purpose of an electrical inspection is to evaluate the condition and integrity of the panel and its components without performing invasive tests that could potentially create safety hazards or damage.

Choosing "none of these" suggests a preference for adhering to safe inspection practices that prioritize thorough visual examination, checking for signs of wear, corrosion, or improper installations, rather than directly measuring voltage or continuity in a potentially sensitive environment.

Tools like wire gauge tools have their place in specific applications but may not be appropriate for the specific context of a standard panel inspection, which is primarily focused on safety and compliance rather than detailed electrical diagnostics.
