Looking to buy high quality flexible metal conduit? Here are some advices and extra details helping you to make the best pick.
Liquid tight flexible metal conduit, this type of conduit is a good choice for covering cable which requires flexibility and protection from areas prone to moisture. Rigid metal conduit is one the hardest wearing, this type of metal conduit is a good solution for cable management in extreme conditions. As the name suggests, this type of conduit cannot be bent, corner pieces and bends are available to join the pieces together. PVC plastic conduit is predominantly installed in wet locations, it’s available in a flexible or rigid type. Plastic conduit can be easily attached to one another with PVC adhesive or connection adaptors. To ensure safety, a green wire can be wrapped around the conduit at the connecting points to achieve the correct grounding, this is because PVC conduit is non- conductive.
Intermediate Metallic Conduit or IMC is lighter weight, metallic conduit and is rated as stronger than other rigid conduit. IMC was first produced by Allied Tube & Conduit. IMC, provided in both threaded IMC and non-threaded IMC forms, is a rigid metallic conduit tubing, typically hot-dipped galvanized steel or stainless steel. The interior of galvanized steel IMC is usually coated with an anti-corrosion layer. Threaded IMC is joined by threaded couplings, C condulets, sweeps and bends. The tubing is cut with a pipe cutter or tubing cutter, and then threads cut using a thread cutting tool. When cutting IMC, take care to remove burrs on the tubing interior that would otherwise damage electrical wires being pulled through the conduit. See more info at Stainless steel flex conduit.
Flexible metal conduit is best known by its nickname “Greenfield,” for its inventor, Harry Greenfield. It is a spiraling metal tubing that bends easily and is commonly used for short, exposed runs in household circuits, such as connections for garbage disposers, hot water heaters and furnaces. FMC is suitable for dry locations only and must be supported every 4 1/2 feet and within 12 inches of each electrical box. It can be used as a ground path only with approved fittings and only where flexibility is not an issue after it is installed. For example, if it’s connected to a motor that vibrates, the conduit cannot be used for grounding.
The liquid tight flexible non-metallic conduit (LNFC) is really a reliable option for a wide range of applications. It is built to be really hard-wearing and protective having the ability to give defense against water and flames. Plus, certain LNFC may be manufactured with multiple layers to provide extra strength. This is basically the most practical form of Plastic Flexible Conduit Fittings to make use of in locations which might be seen as potentially hazardous.
Liquid-tight flexible metal conduit (LFMC) is a special type of flexible metal conduit that has a plastic coating and is used with sealed fittings to make it watertight. It is commonly used with outdoor equipment, such as air conditioner units.
