Conduits are an essential component of electrical systems, providing a secure pathway for power cords and communication wiring. They protect the contents from outside elements such as moisture, dust, dirt, and impact. The many types of conduits available permit a wide range of applications for both residential and commercial projects.
The two most common types of conduits are rigid metal conduit (RMC) and flexible metal conduit (FMC). RMC is made from galvanized steel and is strong enough to withstand extreme conditions. It is often used in underground and exposed applications, as it is able to withstand corrosion, impact, and other environmental hazards. FMC is ideal for tight spaces as its flexible coils conform to turns and bends. It also comes in various materials such as PVC and aluminum.
Non-metallic conduits, such as PVC conduit and corrugated flexible tubing, have also gained popularity over the years due to their cost-effectiveness and ease of installation. PVC conduit is lightweight, non-corrosive, and able to withstand high temperatures. It is widely used in residential applications, although it is not suitable for areas exposed to UV light. Corrugated flexible tubing is made of a tough plastic material that can be bent and shaped to fit in confined spaces.
Conduits are typically used for carrying power or communication cables between two points. In some cases, it is necessary to protect cables from external factors such as water, chemicals, and mechanical forces. For these applications, conduit is often the best solution. Furthermore, conduit is sometimes required by code in specific areas where it can improve safety by providing an extra layer of protection. For example, in schools and hospitals, conduit must be used to protect wiring in case of a fire.
Conduit can also be used in decorative applications such as exterior lighting. PVC conduit is often used to house wires for outdoor lights, as it provides an aesthetically pleasing way to make wiring discreet. Non-metallic coated conduits may also be used in hazardous locations as they provide an extra layer of protection against explosions.
Conduits are an integral part of any electrical system. Their design and durability can vary depending on the application, but all types of conduits provide an effective solution for protecting wiring and cables from external elements. Whether for residential, commercial, or hazardous applications, there is a type of conduit uniquely suited for each situation.
