An electrical conduit is a metal or plastic pipe through which electrical cables are run. Conduit pipes in Malaysia are frequently utilized in areas that are exposed to the elements, such as the outer wall surface. It also covers the wires and is suitable for unfinished areas such as basements, crawlspaces, attics, and even outdoor surface mounting. Electrical conduit may appear to be quite similar to armored cable wire at first glance. Individual wires are wrapped in armored cables, just like they are in an electrical conduit. AC is represented by these cables that can be applied in any open location.
Different Types of Electrical Conduits
- Electrical Metallic Tubing (EMT)
The unbending conduit includes an electrical metal tube (EMT) and it is a common example. It’s usually constructed of galvanized steel, but it can also be made of aluminum. As EMT is thinner and lighter than RMC, it is often referred to as a “thin-wall” conduit. It may also be hard, but with the use of a simple tool known as a conduit bender, it may be readily bent. The fittings and couplings on EMT are entirely secured with compression-type fasteners or setscrews. The tubing is not threaded in the same way that IMC or RMC tubing is. Furthermore, EMT comes in conventional sizes ranging from 1 inch to 1.5 inches. Because it is commonly employed in light commercial and residential construction, EMT is commonly used in exposed indoor wiring. As a result, it’s also critical to put it together with particular watertight fittings.
- Rigid Metal Conduit (RMC)
RMC stands for the rigid metal conduit. It is made of heavyweight galvanized steel and fitted with threaded fittings. It’s typically used outside to provide additional protection from harm. It’s also crucial to provide structural support, especially for electrical boards, cables, and other equipment. RMC may only be purchased in 10- to 20-foot lengths and should have connections on both sides. Rigid metal is among the most expensive electrical wire alternatives on the market. However, it provides far more strength and durability, which is a significant benefit.
- Metal Conduit in the Middle (IMC)
IMC, or intermediate metal conduit, is a thinner and lighter form of RMC. It is, nevertheless, similarly approved for use in all related applications, just as RMC is. IMC is more commonly used in construction in some circumstances since it is lighter and easier to deal with. It also provides the same amount of security as RMC which is seen as a more cost-effective option for situations when money is tight.
- Metal Flexible Conduit (FMC)
FMC is also known as “Greenfield.” It is derived from the inventor’s name. It features a spiral design that allows it to be incredibly flexible. FMC’s adaptability allows it to pass across walls as well as other structures. Standard FMC is typically utilized in dry indoor environments with short run times. Furthermore, FMC is an excellent option for many situations that require tighter bends and close quarters. Regular conduits will be more difficult to bend as a result of the latter. Typical flexible conduit setups include light fixtures, attic ventilation, and water heaters.
- Liquid-tight Flexible Metal (LFMC)
While LFMC is a form of flexible metal conduit with a plastic coating that is utilized with sealed fittings, the parts that make up the full LFMC have made it watertight. Outdoor equipment, such as air conditioner units, uses this metal electrical conduit.
