Five Varieties of Electrical Conduits for Safe Wiring

The electrical conduits can be a kind of fiber, metal, or plastic sleeve that holds and protects wiring in your home or office space. The installation of the conduit is be subject to specific wiring regulations. So, for this reason, it is essential to install the most appropriate one to complement the wants.

Varieties of conduits

The placement in the electrical conduit can be a deciding factor about the chosen material. Most of the conduits they fit 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 many of factors which can be considered while choosing the form of conduit system, including the material with the sleeve, mechanical stiffness and wall thickness. The actual materials are chosen in line with the installation costs, its capacity to resist corrosion, and its mechanical protection.

Rigid Steel

The thickest and heaviest option for the electrical conduits is rigid steel that gives significantly more protection in comparison to the light, flexible versions. Popular materials include aluminum, coated steel and metal. Plus, the different materials are given a special coating to boost the opportunity to resist corrosion. Rigid steel is helpful in an array of applications including outside areas including service feed installations and under driveways.

Intermediate metal

A lighter sort of conduit includes those manufactured with intermediate metal which is an operating selection for protecting cables and insulating electrical conductors. This is a useful selection for exposed walls (basements, garages, etc.) and outdoor applications.


Electrical metallic tubing

The electrical metallic tubing is really a lightweight material and relatively simple to install on indoor applications. It is typically manufactured from aluminum or steel and a popular selection for industrial and commercial buildings.


The PVC conduit is the most cost-effective choice for installing in industrial, commercial, or utility applications. While it's preferred for indoor use, it is still capable of giving sufficient protection against corrosion, moisture and sunlight. Also, it is really an acceptable option for underground applications, but great care must be taken during the entire installation process.


The liquid-tight/seal-tight is able to offer great mechanical strength and is also carried out with various kinds of coatings. It is great for industrial and commercial applications having the ability to 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.
