When inspecting electrical systems, where should one check the condition of wires?

The most comprehensive approach to inspecting electrical systems involves checking the condition of wires in a variety of accessible locations. This is crucial because electrical wiring may be concealed within walls, but it is also often exposed in junction boxes and service boxes. Each of these areas can provide vital clues about the overall health of the electrical system.

Inspecting inside walls alone would limit the visibility of many potential issues such as fraying, corrosion, or improper connections that might be occurring elsewhere. Focusing only on junction boxes or service boxes would miss significant aspects of the wiring that might be in disrepair. By checking a range of accessible locations, an inspector ensures a thorough evaluation, addressing safety concerns and compliance with local electrical codes more effectively. This holistic approach ultimately leads to a more reliable assessment of the electrical system's condition.
