Electrical wiring is the network of conductors used to distribute electrical power throughout a building or structure. It consists of insulated wires, typically made of copper or aluminum, that carry electricity from the main electrical panel to outlets, switches, lights, and appliances. Wiring systems are designed to safely handle electrical loads while minimizing energy loss and preventing hazards such as short circuits and fires. Depending on the application, wiring can be run in conduits, behind walls, through ceilings, or under floors, and may include specialized types like armored cable (BX), non-metallic sheathed cable (NM or Romex), or low-voltage wiring for data and communication. Proper installation in accordance with electrical codes is critical to ensure safety, functionality, and future maintenance. Electrical wiring is an essential component of any residential, commercial, or industrial infrastructure, enabling the reliable and efficient operation of modern electrical systems.
