What is EMT conduit?

Electrical Metallic Tubing (EMT) conduit is a crucial component in electrical systems, providing a protective pathway for electrical wires and cables in various installations. In this knowledge article, we'll explore EMT conduit pipe in detail, covering its characteristics, applications and installation procedures.

Characteristics of EMT Conduit Pipe:

1. Material: EMT conduit is typically made from galvanized steel, offering corrosion resistance and durability. It can also be found in aluminum for specific applications.

2. Thin-Walled: EMT conduit has a thin wall compared to rigid metal conduit (RMC) and intermediate metal conduit (IMC), making it lightweight and easy to work with.

3. Bendable: EMT conduit can be bent using specialized tools to navigate around obstacles and create custom angles without the need for fittings.

4. Connectors and Fittings: Various connectors, couplings, and fittings are available to join EMT conduit sections, connect to junction boxes, or adapt to other conduit types.

Applications of EMT Conduit Pipe:

1. Indoor Wiring: EMT conduit is commonly used for indoor electrical wiring, such as in residential, commercial, and industrial buildings, to protect wires from damage and provide a neat, organized appearance.

2. Lighting Installations: It is often employed for lighting fixtures and electrical raceways in drop ceilings and suspended installations.

3. Exposed Electrical Systems: EMT conduit can be used in exposed electrical systems where aesthetics matter, as it can be painted to match the surroundings.

Installation Procedures:

1. Planning: Begin by planning the conduit route, considering the layout of the electrical system and the location of outlets, switches, and fixtures.

2. Cutting and Bending: Measure and cut EMT conduit sections to the required lengths, and use a conduit bender to create bends as needed.

3. Securing: Secure the conduit to the structure using appropriate straps or hangers, adhering to local electrical codes.

4. Connecting: Use connectors, couplings, and fittings to join EMT conduit sections, and connect them to junction boxes, enclosures, and electrical devices.

5. Grounding: Ensure proper grounding by bonding the conduit to ground when required by electrical codes.

6. Pulling Wires: Carefully pull electrical wires through the conduit using fish tapes or wire-pulling tools.

7. Sealing: Seal conduit ends with appropriate fittings to prevent moisture or contaminants from entering.

8. Painting (if necessary): Paint the conduit to match the surroundings or for added protection.
