5 Kinds of Electrical Conduits for Safe Wiring

The electrical conduits are a sort of fiber, metal, or plastic sleeve that holds and protects wiring in your home or work place. The installation of the conduit is at the mercy of specific wiring regulations. So, because of this, it is important to install the correct one to match the requirements.

Varieties of conduits

The placement from the electrical conduit will become a deciding factor about the chosen material. A lot of the conduits they fit on exposed wall structure, as well as the materials are either rigid or flexible. The most frequent materials include liquid-tight/seal-tight, PVC-coated, EMT, PVC, rigid steel and IMC.

There are a number of things which might be considered when selecting the form of conduit system, including the material in the sleeve, mechanical stiffness and wall thickness. The particular material is chosen depending on the installation costs, its capacity to resist corrosion, as well as mechanical protection.

Rigid Steel

The thickest and heaviest choice for the electrical conduits is rigid steel which provides much more protection when compared to the light, flexible versions. Popular materials include aluminum, coated steel and metal. Plus, different materials are given an exclusive coating to improve the ability to resist corrosion. Rigid steel is helpful in many of applications including outside areas for example service feed installations and under driveways.

Intermediate metal

A lighter form of conduit includes those manufactured with intermediate metal and it is a functional selection for protecting cables and insulating electrical conductors. It is a useful option for exposed walls (basements, garages, etc.) and outdoor applications.


Electrical metallic tubing

The electrical metallic tubing is a lightweight material and comparatively an easy task to install on indoor applications. It is normally created from aluminum or steel plus a popular choice for industrial and commercial buildings.


The PVC conduit is easily the most cost-effective option for installing in industrial, commercial, or utility applications. This specific preferred for indoor use, it is capable of giving sufficient protection against corrosion, moisture and sunlight. Also, it is an acceptable selection for underground applications, but great care needs to be taken through the entire installation process.


The liquid-tight/seal-tight has the capacity to offer great mechanical strength and is carried out with various kinds of coatings. It is great for industrial and commercial applications with the ability to accept a maximum rating of 75° C. Plus, this can be a flexible type of material that would be amazing for areas that have a great deal of flexing or vibrations.
