PVC Conduit is a type of plastic piping system used to protect and route electrical wiring in buildings and construction projects. Think of it as a protective tunnel system for electrical cables, made from a durable plastic material called PVC (Polyvinyl Chloride). Electricians use this because it's safer than having exposed wires, it's water-resistant, and it helps organize wiring systems neatly within walls, ceilings, or underground. It's similar to other types of conduit like EMT (metal tubing) or flexible conduit, but PVC is popular because it's lightweight, doesn't rust, and is cost-effective.
