What is Red Wire?
Red wire is a type of electrical conductor often used in residential and commercial wiring to serve as a secondary live (hot) wire. It typically carries current in 220-volt installations or as a switch leg in circuits, meaning it connects the switch to the electrical load like a light fixture. Red wires are also commonly found in three- or four-way switch configurations and in interconnecting smoke detectors.
In multi-phase systems, red wires help provide power to multiple circuits, ensuring efficiency and safety. However, electricians must be cautious when working with red wires, as these wires are live and can cause electric shock if not handled correctly. Proper labeling and understanding of red wire applications are crucial to maintaining code compliance and ensuring safe electrical installations.
