Rigid conduit, is rigid metal conduit (RMC), is a type of tubing or piping used in electrical wiring installations to protect and route electrical wires. It is made of metal, usually steel, and is designed to provide a high level of mechanical protection to electrical conductors, particularly in industrial and commercial settings.
Rigid conduit is called "rigid" because it is not flexible like some other types of conduits such as electrical metallic tubing (EMT) or flexible metal conduit (FMC). It maintains its shape and provides a sturdy protective barrier for wiring, even in harsh environments.
Key features of rigid conduit include:
Durability: Rigid conduit is highly durable and can withstand physical damage, impact, and exposure to environmental elements.
Fire Resistance: Metal conduit offers fire resistance, which can help contain electrical fires and prevent them from spreading.
Mechanical Protection: It provides excellent mechanical protection for electrical wiring, particularly in areas where the wiring may be exposed to damage from machinery, vehicles, or other hazards.
Corrosion Resistance: Rigid conduit is often made of galvanized steel, which provides corrosion resistance, making it suitable for both indoor and outdoor installations.
Threaded Ends: Rigid conduit typically has threaded ends for easy connection to fittings, boxes, and other conduit sections.
Rigid conduit is commonly used in a variety of applications, including commercial buildings, industrial facilities, power plants, and outdoor installations where wiring needs robust protection against physical damage and environmental factors. It is installed using fittings such as couplings, elbows, and connectors to create a continuous conduit system for wiring.
