In today’s video we want to talk to you about a common component commonly used by most almost all electricians today. Electrical conduit. More specifically, we want to discuss what electrical conduit is, and why it is so widely used in the electrical industry. We, will also look at some of the different types of electrical conduit that are MOST commonly used in industrial, commercial and residential applications.

Electrical conduit is simply a tube that is used for electrical wires to pass through to provide protections to both the wire, and to any persons who might be close to that wire run. It can be found in many different applications, and also many different variations depending on the specific applications it is being used in. Electrical code will often dictate when conduit must be used, as well as what type of conduit for the various different applications you might see it being used.

Let’s look at some of the most common types of electrical conduit, and where you might see each type being used.

First, let’s look at conduit that are made from metal, as these are probably the most used conduits we see today. Rigid Metal Conduit, or RMC is very thick walled type of conduit, commonly steel that has been galvanised, but can also be found in aluminum. This is considered one of the most durable and rugged types of electrical conduit that is used today, and is very common in industrial applications. In most cases, you will need to cut and thread this type of conduit, which can require some special equipment.

Another very common type of metal conduit is Electrical Metallic Tubing, or EMT. EMT is a much less expensive option in comparison to RMC. EMT is a much more thin walled conduit, not providing as much protection. It also much light and easier to work with than RMC, but does not provide the same amount of protection. In most cases EMT will not need to be threaded as it can be used with various different types of connection fittings, which can make it very versatile. EMT is also very common in industrial applications, but is better suited for commercial applications. EMT is generally made of coated steel, although it can be found in aluminum. There are other types of metal conduit such as: Galvanized Rigid Conduit (GRC), or Intermediate Metal Conduit (IMC), but they are not as common in most applications.

Now let’s look at some non-metal variations of electrical conduit. Must like with metal, there are many different types of non-metal conduit such as: PVC, Fiberglass Reinforced Conduit, Rigid Nonmetallic Tubing (RNT).

There are also several types of flexible non-metallic conduits that can be used an a variety of different applications. For the purpose of this video we will focus on the most common type of non-metallic conduit, which is PVC. PVC conduit is considered by most to be one of the lightest and most easy to use types of electrical conduit that we use. Also, PVC conduit is typically found at a lower cost than some of the other options. You can find in several different wall thicknesses depending on your applications. It is very common to see PVC conduit used underground and embedded within concrete because of its non-corrosive characteristics. There are many different sizes and fittings that can be used, which makes it very versatile for many different applications. It is not intended for areas that will be exposed to direct sunlight, as this can degrade the material over time. For the most part, PVC is a great option for the majority of underground scenarios, and is commonly used in industrial, commercial and residential environments

As you can see there are many different types of electrical conduit, and many different use cases that is can be found it. It is a tool that has allowed electricians to do there job more effectively, while providing a more safe environment for both the wires in the conduit, and the people around it.
