The first thing that comes to every electrician’s mind when they start a wiring installation in any commercial or residential facility is selecting the type of wire used. Not only the right wiring type enhances work durability, but it also reduces the likelihood of future damage.
Electrical conduits are one of the essential components of the wiring system. In this article, we’ve compiled a comprehensive guide on electrical conduits. Let’s begin.
What Is an Electrical Conduit?
Electrical conduits consist of plastic or metallic piping that encloses the installation of electric wires. They’re also made from various other materials, like fiber, fired clay, etc., depending on the application. These are generally used in exposed areas, like walls, crawlspaces, attics, basements, and sometimes surface-mounted places.
An electrical conduit might resemble an armored wiring/cable, but there’s a slight difference. Electrical conduit enclose or encase these armored cables and wiring, installed in exposed areas.
Types of Electrical Conduits
Here some common types of electrical conduits used in commercial or industrial electrical services.
1. Electrical Metallic Tubing (EMT)
Typically made of galvanized steel, metallic electrical tubing is an unbending electrical conduit. It’s rigid, thin-walled, and lightweight.
Generally, electricians install EMT conduits with completely secured couplings and fittings with the help of fasteners. Two standard sizes for EMT include 1 inch and 1.5 inches. These are primarily used in exposed indoor wiring in light commercial and industrial construction.
2. Rigid Metal Conduit (RMC)
Installed with threaded fittings, a rigid metal conduit is heavyweight and one of the costly alternatives for electrical wiring. Due to its strength and durability, it’s used in outdoor applications to protect against environmental damage. It’s available for sale only when buyers are interested in buying at least 10 to 20-foot lengths of the conduit.
3. Flexible Metal Conduit (FMC)
Also referred to as ‘Greenfield,’ a flexible metal conduit is spiral and thoroughly adaptable to different walls and structures. It’s generally installed in dry indoor locations, lasting for a short period.
Other applications for FMC include water heaters, attic vents, close quarters, lights, etc.
4. Intermediate Metal Conduit (IMC)
IMC is similar to RMC in terms of application, but it’s lighter in weight and thinner in shape. They’re the best alternative option for those construction projects where high costs are a significant concern.
5. Rigid PVC Conduit
Rigid Polyvinyl Chloride (PVC) conduit is like a plastic plumbing pipe that resists corrosion. Constructors enclose these conduits, plastic fitting to install in the ground or other applications directly.
Why Use Conduit Wiring?
Electricians use conduit wiring for the following reasons:
- To protect wires from damage as many wires when getting in touch with water or atmospheric moisture forms rust and deteriorate in function;
- To provide gaps, primarily for the creations of splices and spaces in conductors;
- To provide room for connecting additional wiring in the future;
- To firmly connect several conduit sections; and
- To form a mounting outlet for wiring devices and light fixtures.
