Wiring systems are essential components in electrical installations, providing pathways for electrical current to flow safely and efficiently. They consist of various elements, including wires, cables, connectors, and switches, which work together to distribute electricity throughout a building or structure. Proper wiring ensures that electrical devices operate correctly and reduces the risk of hazards such as short circuits or electrical fires. Different types of wiring systems are used depending on the application and environment. For example, residential wiring typically uses non-metallic sheathed cables, while commercial wiring may involve conduit systems for added protection. Understanding these systems is crucial for maintaining electrical safety and functionality.
