Electrical wiring refers to the system of conductors and devices that transport electricity throughout a building or structure. It includes various components such as wires, circuit breakers, and outlets, which work together to provide power for lighting, appliances, and other electrical devices. Proper installation and maintenance are essential for safety and efficiency. The wiring is typically made from materials like copper or aluminum, which are good conductors of electricity. Different types of wiring, such as non-metallic sheathed cable or conduit, are used depending on the application and local building codes. Understanding electrical wiring is crucial for both homeowners and professionals in the construction industry.
