Metallic conduit fittings are components used in electrical installations to connect and secure metallic conduit pipes. Metallic conduits, such as rigid metal conduit (RMC), intermediate metal conduit (IMC), or flexible metal conduit (FMC), provide a protective pathway for electrical wiring in commercial, industrial, and residential buildings. The conduit fittings are essential for joining sections of conduit, transitioning to different conduit types, and connecting conduit to electrical boxes, junction boxes, or other electrical equipment.
Some common types of metallic conduit fittings include:
Connectors: These fittings are used to join two sections of conduit together. Examples include couplings, connectors, and compression fittings.
Elbows: Elbows are used to change the direction of the conduit, allowing it to navigate around corners or obstacles. They come in various angles, such as 90 degrees or 45 degrees.
Conduit Bodies: Conduit bodies, also known as conduit junction boxes or LBs, are used to provide access points for making wire pulls, splices, or changes in conduit direction.
Bushings: Bushings are used to protect wires from sharp edges at the entrance or exit points of conduit. They prevent damage to the insulation and ensure a smooth transition.
Couplings: Couplings are used to join two conduit pipes together in a straight line. They are typically used when extending conduit runs or repairing damaged sections.
Metallic conduit fittings are typically made from materials like steel, aluminum, or brass, depending on the specific application and environmental conditions. They are designed to provide secure connections, electrical continuity, and mechanical protection for the enclosed wiring.
It's important to note that metallic conduit fittings should be selected based on the specific type and size of the conduit being used to ensure proper fit and compatibility. Additionally, electrical codes and regulations dictate the use of appropriate metallic conduit fittings in various electrical installations to ensure safety and compliance.
