Final answer:
Home inspections for the electrical system primarily describe the readily accessible and observable portions. Plastic insulation on wires minimizes shock hazards and reduces thermal hazards.
Step-by-step explanation:
Home inspections for the electrical system, per §197-5.9, are primarily aimed at describing the readily accessible and observable portions of the system. This includes visible wiring, outlets, switchgear, and other electrical components that can be directly evaluated without the need for demolishing or damaging parts of the property. Inspectors do not ordinarily explore hidden or inaccessible components, as this may require specialized tools and risk causing damage. They also typically limit their inspections to the interior electrical system, with outdoor electrical features evaluated separately if required.
As for safety considerations, plastic insulation on live or hot wires primarily helps mitigate shock hazards by acting as a barrier between the electrified wire and any potential conductive material. It can also reduce thermal hazards to some extent, although this is secondary as its main function is not for thermal insulation.
