Non-metallic conduit is a versatile product that has a variety of applications for indoor and outdoor locations. Non-metallic conduit is used in fixture whips, data centers, electric signs and outdoor lighting, HVAC, pool and spas and locations with exposure to sunlight and weather conditions and more.

Types of Non-metallic Conduit

There are different types that are suitable for different applications. These include:

Rigid Non-metallic Conduit (RNC): This is a non-metallic, unthreaded, smooth walled tubing. It has been used for several years in the United States, Canada, and Europe but has been under scrutiny for years due to the fact that it is made of combustible materials.

Electrical Non-metallic Tubing (ENT): This is a thin-walled corrugated tubing that is moisture resistant and flame retardant. It is pliable and can be bent by hand. Installation is easy due to its flexible properties. It is not threaded due to its corrugated shape, although some fittings may be.

Liquid-tight Flexible Non-metallic Conduit (LFNC): this refers to several types of flame resistant non-metallic tubing. It is recommended as a raceway for the installation of approved conductors with a nominal rating of 600V or less for non-hazardous locations. Interior surfaces can be smooth or corrugated.

It is good to be familiar with the properties associated with the non-metallic conduit, so you know which are best to use in various applications. As compared with metallic conduits, the non-metallic counterparts are generally lower cost. They are also more resistant to corrosion. These factors contribute to the fact that they are becoming more popular in underground installations.

If you are planning on working on the electrical wiring in a building or structure, it is a good idea to do some research on the various types of conduit. This way, you will be able to decide on the material that works best for you.
