Which of the following must a home inspector report on in the electric system?

A home inspector must report on the amperage and voltage rating of the service because these measurements are critical indicators of the electrical system's capacity and safety. Understanding amperage and voltage ratings helps to determine if the electrical service can adequately meet a home's power demands without being overloaded, which could lead to hazards such as overheating or electrical failure.

In the context of a home inspection, it is essential to assess whether the home's electrical system is up to code and suitable for the appliances and systems used in the residence. This information is vital for potential buyers, as it directly affects the functionality and safety of the home.

While other aspects of the electrical system may be relevant, such as low voltage wiring systems, active remote control devices, and underground installations, the primary focus for home inspectors is usually on the capacity and safety of the electrical service itself, making amperage and voltage ratings a fundamental aspect of their reporting responsibilities.
