Metal conduit is a type of tubing used to protect and route electrical wiring in various construction and industrial applications. Made from materials like steel or aluminum, it provides a durable and secure pathway for electrical cables, helping to prevent damage from physical impacts and environmental factors. There are different types of metal conduit, including EMT (Electrical Metallic Tubing), RMC (Rigid Metal Conduit), and IMC (Intermediate Metal Conduit). Each type has specific uses and benefits, such as flexibility, strength, and ease of installation, making them suitable for both indoor and outdoor electrical systems.
