Residential wiring refers to the electrical systems installed in homes to provide power for lighting, appliances, and other devices. This wiring includes various components such as circuit breakers, outlets, and light fixtures, all designed to ensure safe and efficient electricity distribution throughout the house. The installation of residential wiring must comply with local building codes and safety standards to prevent hazards like electrical fires. Typically, a licensed electrician handles the wiring process, which involves running cables through walls, connecting them to the main electrical panel, and ensuring proper grounding for safety.
