Indoor wiring refers to the electrical wiring installed within buildings to provide power to outlets, lighting fixtures, appliances, and other electrical devices. It typically uses insulated wires contained within walls, floors, or ceilings, ensuring safety and protection from environmental factors. Indoor wiring systems are governed by building codes and standards to ensure proper installation and compliance with safety regulations. They include circuits for various purposes such as lighting, heating, and powering electronic equipment, with components like circuit breakers or fuses to protect against electrical faults. Indoor wiring designs prioritize functionality, ease of access for maintenance, and aesthetic integration with interior spaces.
