Conduit can be used for connecting wires, cables, and power in a variety of applications. It comes in various types, sizes, and connectors. This guide will help you figure out how to connect conduits to electrical enclosures, panels, and boxes. When working with an electrical conduit, make sure you have all the necessary tools to do the job safely. It is also important to understand the proper use of the fittings so you can ensure the integrity of your project.
Set-Screw Couplers
A set-screw coupling is a connector used to connect two lengths of 3-inch steel EMT conduit. They are zinc-plated steel and are approved for use in concrete-tight applications. A set-screw coupling is also known as a setscrew coupling because of its concrete-tight connection. A set-screw coupling is not recommended for underground applications.
Set-screw couplings are designed to join lengths of EMT or IMC conduit. They are made of steel and are zinc-plated to resist corrosion. These couplings can be rated for electrical applications of 600 volts or more. Their heavy-gauge steel construction ensures solid grounding and mechanical protection for the two conduits. You can also use them to connect the ends of the EMT and IMC conduit.
C-Shaped Bodies
Conduit Fittings come in a variety of types and sizes. Some are threaded, while others are not. All types have some connection methods in common. Threaded couplings connect to threaded conduit and couplings have a C-shaped body. These fittings typically have one piece with a nut or locknut on the outside. C-shaped bodies for conduit fittings are available in stainless steel, cast iron, or copper-free aluminium.
LL-shaped conduit bodies are identical to C-shaped bodies, except that their inlet aligns with the access and the outlet is on the other side. They are also used for 90-degree bends. LB-shaped bodies, on the other hand, are shorter than L-shaped bodies and are used by electricians for circuits passing through exterior walls. They are a good choice when you need to connect multiple conduits with different lengths and configurations.
When installing a C-shaped conduit body, you should always use two people. One person should train the other to pull the wires through the access point. Wires should be grouped so that they don't clump together. It is helpful to use a lubricant to keep wires from scraping against the hub. Once the wires are properly placed, you can start installing the conduit body.
Galvanized Rigid Conduit
Generally, a galvanized rigid steel conduit is made of mild steel and is used as a steel raceway system for electrical conductors. Its circular cross section makes it ideal for physical protection and routing of wires, as well as equipment grounding. Unlike other types of pipes, rigid steel conduit does not contain any iron or other conductive materials, which could lead to electrical shocks. Galvanized rigid steel conduits are also commonly used in commercial buildings and are available in various diameters, including the patented Kwik-Couple coupling.
A complete line of RIGID/IMC FITTINGS is available from ERI(r), including threaded couplings, chase nipples, and connectors. These fittings are designed with quality and innovation in mind and are available in zinc, steel, and malleable alloys. Their features include deep-slot, captive tri-drive screws, and smooth throat openings. Its corrosion-resistant coatings make it ideal for any application.
Electrical conduit is an important part of building and construction projects. It provides protection for the enclosed conductors and makes installation and maintenance easier. The installation process is also simpler and cheaper than using multiple runs of cable or custom composite cables. Moreover, it is more convenient to make changes to wiring if necessary. This type of conduit can be easily removed and installed to adapt to changing electrical needs. In addition, it prevents accidental electrical shocks and protects electrical wiring from fire.
