Pvc coated flexible conduit buying recommendations
Searching to purchase the best flexible conduit ends? Here are some recommendations and extra details helping you to make the best pick. There are seven different types of conduit used commonly in residential and light commercial wiring. Rigid metal conduit, or RMC, is heavy-duty galvanized steel tubing that is installed with threaded fittings. It is typically used outdoors to provide protection from damage and can also provide structural support for electrical cables, panels, and other equipment. RMC is sold in 10- and 20-foot lengths and has threads on both ends.
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.
Rigid metal conduit is a heavier gauge steel electrical conduit using threaded couplings and fittings and is the thickest, or stiffest of the conduit materials used for electrical wiring. A typical RMC and often the only RMC residential application is to enclose the electrical service entry wiring from the electrical company’s overhead wires at the mast-head down to the electrical panel mounted on the building wall.

The usage of Flexible Cable Conduit is a practical process to be certain the electric wires installed in the home or office receive proper protection. The flexible kind of conduit will be the easiest to use in comparison with alternatives like rigid plastic or metal. The flexible conduit has the down-side of not being so strong and gives less protection. But, for the do-it-yourself enthusiast working in the home, the flexible material is usually favored due to its simplicity.
The ID and OD means inner diameter and outer diamter of flexible conduit. OD is the maximum of flexible conduit, and is a fixed number that can not be deviated from. Flexible conduit are always corrugated inner and outer, so we’d better leave more space inner to make wires and cables easier to through. So we should leave 20% space based on inner diameter. It may sound backward but use the diameter of the conduit as a guide to the service needed. It is better to use a conduit that is too big than one that is too small.
