A conduit is a tube or channel that protects and routes electrical wires and cables in buildings and construction projects. Think of it as a protective pathway that keeps electrical wiring safe and organized, similar to how a tunnel protects cars from the elements. Conduits can be made of different materials like metal or plastic, and they're essential in construction because they help keep electrical installations safe, meet building codes, and make it easier to maintain or replace wiring when needed. You might also hear them called "electrical conduits," "wiring ducts," or "raceways."
