Conduit is a type of pipe that is used to protect and guide electrical wires. There are several important things to consider before purchasing conduit.
There are several different types of conduit, each with its own advantages and disadvantages, so it's important to choose the right type for your specific application.
Flexible metal conduit (FMC) is known in the construction industry as Greenfield or Flex. it is recommended for use in dry indoor locations because it is not waterproof. Its flexibility and lighter weight make it easier to install than rigid conduit. It is often used in interior walls, cubicles and office ceilings in houses and office buildings (for connecting power to light fixtures).
Waterproof, flexible, metallic conduit (LFMC) is often covered with a waterproof plastic coating to protect against moisture. Its flexibility allows it to be used in tight bends where rigid conduit is difficult to install. Typical uses include bridges, underground, paper mills, petrochemical facilities, and water treatment plants.
Liquid-tight, flexible, non-metallic conduit (LFNC) is suitable for use in dry, wet or greasy locations. It can be used in indoor or outdoor environments for industrial and commercial applications. Typical uses include in-ground, HVAC installations, swimming pools and spas.
Conduit comes in a range of sizes and it is important to choose the right size for your wiring. If the conduit is too small, it will be difficult to pull the wires through, and if it is too large, it will be more expensive and may not provide the necessary protection for the wires.
The length of conduit will depend on the distance between the electrical panel and the outlet, switch or other device you are wiring. It is important to carefully measure the distance and purchase enough conduit to cover the entire length.
In addition to the conduit itself, you will need to purchase fittings and accessories such as elbows, couplings and connectors to connect pieces of conduit together and to connect them to the electrical box. Be sure to select the correct fittings and accessories for your specific application.
If conduit is only needed until your next remodeling project, you can purchase less durable, lower cost conduit and accessory options.
