Electrical conduits refer to an electrical system accustomed to protect and provide the path of electrical wiring. Electrical conduits are constructed with metal, plastic, or fiber and may be rigid or flexible. Conduits has to be installed by electricians following standard regulations, as those provided by the National Electrical Code (NEC). Here are the most typical types of electrical conduits.
The thickness of Conduit Fittings Wholesale the electrical wiring from being hit and allows so that it is threaded. Galvanized rigid conduits are being used by electricians in commercial and industrial applications normally available in 10 feet and 20 feet lengths. This sort of electrical conduit can be used above grade and it has threads for both ends with a coupling on a single end.
Setting up Rigid Steel Conduit (RSC) is protected by Article 344 of the National Electrical Code® (NEC®). The rigid metallic conduit can usually be treated to avoid corrosion by applying different coatings for the conduit. This is the heaviest-weight and thickest wall conduit offered in trade sizes ½ through 6.
Another instance of a rigid electrical conduit is definitely the EMT, also called Electrical Metallic Tubing. An EMT conduit is constructed of steel; sometimes, aluminum can also be used, less than a galvanized rigid conduit and lighter than the usual GR conduit.
EMT is also a very well liked material in commercial and industrial buildings because it can be bent to specific radius and directions in fact it is thinner than RMC. During the past several years, Plastic Flexible Conduit have become popular in residential construction because it gives an exterior corrosion resistance surface. EMT is actually a listed steel raceway of circular cross section, which is unthreaded, and normally 10 feet long.
Electrical non-metallic tubing is yet another example of electrical conduit made of a thin-walled corrugated tubing, moisture-resistant and flame retardant. The non-metallic electrical conduit may be bent yourself and might be simple installed due to the flexible properties. However, fitting utilized to connect non-metallic tubing are rigid and can not be bent. If you are looking to get a faster installation and minimize labor cost, this is actually the one to consider.
Flexible Metallic Conduit or Liquid-tight Flexible Metal Electrical Conduit (LFMC)
A versatile metallic conduit forms a hollow tube in which electrical wires are passed. It is strongly advised in dry areas. The Flexible Metallic Conduit also known as greenfield of flex, does not maintain permanent bend and it can be used where EMT is impractical to utilize.
However, a liquid-tight flexible metal conduit is protected with a plastic waterproof coating. Its interior is very similar to the flexible metallic conduit. It is strongly recommended to be used generally speaking wiring, wet or dexlpky51 locations. It may also be used to direct burial; concrete embedded, and site lighting jobs.
Liquid-tight Flexible Nonmetallic Conduit (LNFC) is an additional term for a number of flame resistant kinds of non-metallic tubing.
This particular Metal Flexible Conduit is usually recommended being a raceway for installing approved conductors having a nominal rating of 600 Volts or less for non-hazardous locations. The interiors on this conduit can be corrugated or smooth.
An aluminum conduit is a rigid conduit widely used in commercial and industrial applications. These sorts of electrical conduits are utilized to prevent corrosion and they are the favorite conduit used in locations where huge amounts water and corrosion-prone areas. Aluminum can not be directly baked into concrete since the metal reacts with all the alkalis in cement however it might be protected with additional coatings to avoid concrete from affecting the conduit. It is actually normally employed in concrete slabs or walls.
PVC is the lightest conduit material in most cases the least expensive type of conduit.
PVC pipes can vary in thickness based on the uses and the location where the PVC will likely be installed. The PVC conduit resists moisture and corrosion although the tubing is non-conductive an extra grounding conductor has to be passed into each conduit. PVC conduit carries a higher thermal coefficient of expansion allowing the conduit to expand and contract. Take note the installing PVC underground in multiple or parallel run configurations, mutual heating could potentially cause problems on cable performance.
