Exposed wiring is a significant concern during an inspection primarily because it poses a serious electrical hazard and fire risk. When wiring is not properly insulated or protected, it can lead to electric shocks, short circuits, or create conditions that increase the likelihood of fires. This is due to the potential for arcing, where electricity can jump from the exposed wires to conductive surfaces, potentially igniting surrounding materials. Furthermore, exposed wiring can also indicate a lack of proper electrical installation practices, increasing the overall safety hazard in a home. Properly protected and insulated wiring is crucial for maintaining safe electrical systems within residential buildings.
