Working With or Without Electrical Conduits

The use of electrical conduit is practical for routing and protecting electrical wiring. It comes in a variety of materials, such as fired clay, fiber, plastic and metal. Also, the conduit is either rigid or flexible. For the most effective installation, it is important to use the correct size that offers enough space for the wires that run through it.

Here are a few of the differences of working with or without the electrical conduit:

Wiring with Conduit

A major benefit of using the electrical conduit throughout the home is the ability to give greater protection to the wiring. The fired clay, fiber, plastic or metal material used to manufacture the sleeve is strong and durable, and has the potential to last for a very long time.

By using the conduit it is a lot easier to renovate or replace existing applications that were installed in a building. Plus, the process of passing wires through a smooth sleeve is a much easier process compared to working with random sized holes cut into the walls.

Also, in the event of a short of the wiring, it is a lot more straightforward to find and repair the defective wire when it is concealed and kept together in a conduit, especially if the installing took place behind a wall or underground.

Installing wiring without conduits

Even though the conduit can give the extra protection for the wiring, it does have its limits, and isn’t a practical choice for every installation. A common issue relates to the small space that requires the wiring to go around a bend. While it is possible to use the flexible conduit this isn’t always able to fit the tight areas. Also, in the small space the size or width of the conduit will need to be quite small and the reduced size and volume may not provide enough room for the various wires to fit. In situations like these it may be more practical to install the wiring without the use of conduit.

The use of conduit will increase the overall cost and time of installing the wiring in the home. If the rigid sleeve is being used and it needs to be bent it will be necessary to use an expensive piece of equipment to achieve the required bent angel. Also, greater care needs to be taken throughout the installation process, with extra care taken to avoid getting cut on any piece of conduit that has been cut.

6 Types of Electrical Conduits

Electrical conduits are used when installing new electrical wiring to help provide the route and give a high level of protection. It is made in many different materials, including fiber, plastic or mental and can be flexible or rigid. Here are a few of the most popular types of electrical conduits:

Galvanized steel

The galvanized steel conduit is entirely rigid to provide useful protection for the electrical wiring. This method is most common in industrial or commercial electrical installation. The typical length of the conduit is in the region of 10 to 20 feet, and multiple pieces are easily threaded together. Plus, it is easy to protect against corrosion by applying the right protecting paint. It is one of the thickest and heaviest in weight to make it a practical choice for the most difficult environments.

Metallic

Metallic tubing (also referred to as EMT) is mostly made of aluminum or steel. It is more cost-effective and lighter than the alternatives in galvanized steel. This conduit is flexible to give more freedom in installation and a popular choice with industrial and commercial buildings. Also, the outer surface is naturally corrosion resistance, so there isn’t any need to provide a special coating.

Electrical non-metallic

The electrical non-metallic tubing is made of a thin, corrugated type material that is flame retardant and moisture-resistant. It has high flexible properties and is easily shaped by hand to fit the tight or awkward spaces. This is a perfect type of conduit for those in search of low labor costs and fast installation.

Flexible Metallic

The standard flexible metallic conduit is a practical choice for the dry environments and is simply a hollow tube with space for the electrical wires to pass through. There is also a liquid-tight flexible conduit in metal that has a waterproof coating. This is more practical for the damp locations and can be embedded in concrete or buried in other areas.

PVC

PVC is the most common type of conduit used for residential and commercial installations. It is a very affordable option and the PVC pipes are thick to give a useful amount of protection. PVC is naturally able to avoid issues with corrosion and resists moisture.

Aluminum Electrical

The aluminum conduit is a rigid option for the commercial applications and a practical option for areas that are prone to high moisture content. It is a useful choice to use in concrete slabs or walls, but cannot be buried in concrete because the alkali content in the cement can cause a negative reaction.
