Finding The Best Electrical Conduit for Your Project
If you work in the electrical field, are a contractor who spends a lot of time with electricians, or an at home do-it-youselfer, you should be familiar with electrical conduits. These conduits are electrical supplies that are used to protect electrical wiring. They are tubes that wrap around the wiring and may be made of metal, plastic, fiber or fired clay. The tube is usually rigid but can sometimes be flexible as needed. This article will take a look at some of the different types of electrical conduits.
PVC Conduit: This is the lightest, most common and affordable type of conduit. It protects against moisture and corrosion. This makes it a good conduit for underground applications. Its high thermal coefficient allows it to expand and contract.
Electric Metallic Tubing (EMT): This is a rigid electrical conduit that is made of steel. It is often used in commercial and industrial buildings because it can be bent into a specific radius or direction and it is thinner than some other types of the conduit than can be used for similar purposes. Its resistance to corrosion has also made it more popular in residential buildings in more recent years.
Electrical Non-Metallic Tubing: The non-metallic properties of this conduit make it easier to bend. Because of this, installation can be faster and easier resulting in lower labor costs. The non-metallic tubing is moisture resistant and flame retardant.
Aluminum Electrical Conduits: Aluminum electrical conduits are often used in commercial and industrial applications. They prevent corrosion making them a popular choice in areas where there is a lot of water and corrosion is likely. It is often used in concrete slabs or walls.
Flexible Metallic Conduit: This is a hollow tube that electrical wires are passed through. It’s recommended for dry areas. It does not maintain a permanent bend and can be a good substitute for EMT conduit. There is also a liquid-tight flexible metallic conduit that is covered by a plastic waterproof coating. It’s recommended for use in general wiring and wet or damp locations.
Liquid Tight Flexible Non-Metallic Conduit: This is a non-metallic, flame resistant tubing. It’s recommended as a raceway for the installation of approved conductors with a nominal rating of 600V or less.
Electrical conduits are commonly found at any electrical supply stores. Electricians may prefer to purchase them at an electrical wholesale outlet. Those opting to buy conduit at websites that sell electrical supplies online should make sure to read the description carefully so they know they are buying the conduit that best suits their needs.
If you are doing a job that requires electrical conduit, factors such as the type of job you are doing, the location where you will be installing the wiring and your budget should all be considered. Hopefully, this article has given you some insight in determining which conduit will work best for you. Good luck with your next electrical wiring project.
