Different types of electrical conduits and applications Electrical conduits are metallic or plastic pipes that provide a route for the wires while protecting them against physical and chemical damage. These can be rigid or flexible and the choice in terms of material, flexibility and size depends on the application and environment as well as the electrical code and building requirements. The conduits are essential components that protect the wiring from physical damage, water, chemicals, corrosives, vibrations and other conditions. Common construction materials include metals such as steel and aluminum, and plastics such as the PVC.

It is suitable for residential indoor as well as outdoor applications to protect wires for light fixtures and in garages. Flexible metal conduits This type is suitable for areas with tight bends or those that are difficult you install the regular rigid conduits. These are easy to bend and achieve the desired shape. The flexible metal conduits are common in water heaters, attic vents, can lights and other similar installations. The conduits are usually ribbed and have the corrugated wire appearance. This can flex and bend freely and suitable for installation the rigid conduit would have to make too many turns and bends hence making it impractical. One of the benefits of the flexible in such as situation is the ability to provide protection without confining it to only the straight lined sections. In addition, it is has the ability to withstand vibrations such as when connecting motors and other equipment where regular movements are common. Plastic conduits The plastic conduits are light, inexpensive and easy to install. Common types include rigid PVC pipes, liquid-tight flexible nonmetallic conduit (LFNC) and electrical nonmetallic tubing …show more content…

Additionally, it is important to take into account the type of cables, current carrying capacity as well as other conditions such as temperature rating of the cable insulation. The electrician should use the charts to find out the number of conductors allowed to run through the pipe. Running excess cables inside a conduit reduces the free airspace hence for adequate air circulation and this can lead to increased temperature within the conduit. An excessive temperature ends up overheating the conductors and degrading the cable insulation. Conclusions Electrical conduits protect the cables from abrasion, drywall screws, mechanical damage, and exposure to UV rays, chemicals and other external conditions. They provide a means of protecting, supporting, fastening and directing the electrical conductors. However, with so many types of conduits, it can be a challenge determining the one that is deal for a particular application. But installers can get help for major suppliers such as US electrical
