An EMT (Electrical Metallic Tubing) conduit fitting, also known as an EMT connector or EMT accessory, is a component used in electrical installations to connect, secure, or modify EMT conduit. EMT conduit fittings play a crucial role in providing a secure and safe path for electrical wires and cables, while also facilitating the connection of conduit to junction boxes, enclosures, or other conduits. These fittings are essential for creating a complete and compliant electrical conduit system. Some common EMT conduit fittings include:
Set-Screw Connectors: Set-screw connectors are used to connect EMT conduit to junction boxes, enclosures, or other conduits. They feature screws (set screws) that, when tightened, secure the conduit in place. Set-screw connectors are easy to install and provide a reliable connection.
Compression Connectors: Compression connectors have a compression ring or ferrule that tightens down onto the EMT conduit when the connector is installed. This design creates a watertight seal and is often used in wet or outdoor environments where moisture resistance is important.
Squeeze Connectors: Squeeze connectors, also known as Squeeze-Type Connectors, are designed for quick and easy installation. They have a hinged design that clamps onto the EMT conduit when squeezed or compressed, creating a secure connection. Squeeze connectors do not require additional hardware.
Set-Screw Couplings: Set-screw couplings are used to join two EMT conduits together. They have set screws on both ends, allowing you to secure two EMT conduits within the coupling. Set-screw couplings are often used to extend conduit runs or connect separate conduit sections.
Locknuts: Locknuts are used in conjunction with other EMT fittings, typically in securing conduit to junction boxes or enclosures. They thread onto the conduit and provide a secure attachment point when tightened against the box or enclosure.
Conduit Straps: Conduit straps, also known as one-hole or two-hole straps, are used to secure EMT conduit to walls, ceilings, or other surfaces. These fittings prevent the conduit from moving or sagging and help maintain the conduit's position.
Bushings: Bushings are used to protect wires from the sharp edges of conduit openings. They are typically inserted into the end of the conduit to prevent wire damage and abrasion.
These EMT conduit fittings are designed to meet specific needs in electrical installations, including securing and connecting conduit, protecting wires, and ensuring code compliance. The choice of fitting depends on the installation's requirements and the specific components being connected or protected.
