What should the inspector describe regarding the electrical system?

The amperage rating of the service is a critical aspect of the electrical system that an inspector should describe. This rating indicates the maximum amount of electrical current that the service can safely carry, which is essential for determining whether the electrical system can handle the demands of the home’s appliances and other electrical loads. An inadequate amperage rating can lead to overloaded circuits, posing risks of overheating and potential electrical fires. By reporting on the amperage rating, the inspector provides valuable information to prospective buyers or homeowners about the system's capacity and safety.

The other options pertain to different areas of inspection that do not directly relate to the electrical system. The location of the nearest fire extinguisher is important for safety but is not a component of the electrical system itself. The type of insulation used in the building pertains to thermal efficiency and energy use but does not provide insight into the electrical capabilities or safety of the home. Similarly, the depth of foundation footings relates to structural integrity rather than electrical safety or performance. These elements, while important in their own right, do not address the specifics of the electrical system that must be conveyed during an inspection.
