5Types of Electrical Conduits for Safe Wiring

The electrical conduits certainly are a kind of fiber, metal, or plastic sleeve that holds and protects wiring in your house or work place. The installation of the conduit is at the mercy of specific wiring regulations. So, for this reason, you must install the right one to check the requirements.

Varieties of conduits

The positioning with the electrical conduit will end up a deciding factor on the chosen material. Almost all of the conduits are placed on exposed wall surfaces, and also the material is either rigid or flexible. The most frequent materials include liquid-tight/seal-tight, PVC-coated, EMT, PVC, rigid steel and IMC.

There are a variety of things which are considered in the process of deciding on the kind of conduit system, including the material in the sleeve, mechanical stiffness and wall thickness. This material is chosen depending on the installation costs, its capability to resist corrosion, and its particular mechanical protection.

Rigid Steel

The thickest and heaviest selection for the electrical conduits is rigid steel that gives now more protection compared to the light, flexible versions. Popular materials include aluminum, coated steel and stainless steel. Plus, the several materials get a particular coating to raise the ability to resist corrosion. Rigid steel is effective in a wide array of applications including outside areas like service feed installations and under driveways.

Intermediate metal

A lighter form of conduit includes those manufactured with intermediate metal and is also a sensible selection for protecting cables and insulating electrical conductors. This is the useful decision for exposed walls (basements, garages, etc.) and outdoor applications.

Electrical metallic tubing

The electrical metallic tubing is a lightweight material and relatively easy to install on indoor applications. It is typically created from aluminum or steel along with a popular decision for industrial and commercial buildings.


The PVC conduit is easily the most cost-effective option for installing in industrial, commercial, or utility applications. Even though it is preferred for indoor use, it's still able to give sufficient protection against corrosion, moisture and sunlight. Also, it becomes an acceptable option for underground applications, but great care must be taken during the entire installation process.


The liquid-tight/seal-tight has the ability to offer great mechanical strength and it is finished with several types of coatings. It is always good for industrial and commercial applications income accept a maximum rating of 75° C. Plus, it is a flexible form of material that would be ideal for areas that have a lot of flexing or vibrations.
