Searching to buy high quality corrugated flexible conduit? Here are some advices and extra details helping you to make the best pick. Flexible metal conduit (FMC) is also called “Greenfield,” after the name of its inventor. It has a spiral construction that makes it flexible so it can snake through walls and other structures. Standard FMC is used in dry indoor locations, often for short runs between a wall box and a motor or fixed appliance, such as a garbage disposer.
Rigid polyvinyl chloride conduit is plastic tubing that’s sort of a thin version of PVC plumbing pipe (and is usually gray instead of white). It can be heated and bent to change direction but is more commonly routed with elbow fittings. Connections are solvent-glued, similarly to the way PVC plumbing pipe is handled. The glued connections make the raceway watertight, so PVC can be used for outdoor and underground applications, as well as for dry and even corrosive locations. Because PVC is nonconductive, this conduit cannot serve as a ground path.
The general procedure for using thin wall conduit is similar to the use of steel armor cable. The big difference is that conduit cannot be “snaked” through openings in ceilings and walls. You must have full access to joists and studs to install electrical conduit. So you probably won’t want to use it unless your local code requires it. IMC is typically used in hazardous locations, and in its stainless steel formulation, IMC is widely used in the food and beverage industry, in chemical plants, in cosmetic and pharmaceutcial industries, in refineries, in pulp and paper mills, in marine and coastal sites, in other corrosive environments. An advantage of IMC is its larger interior diameter compared with RMC of the same nominal sizes, making it easire to pull wires. Discover even more information on flexible plastic conduit.
Flexible metallic conduit (also known as FMC) can be a practical choice for the large construction projects, for example building the underground car park. This particular conduit relies on interlocking metal coils to produce a long tube that lets the wires move through. By interlocking the individual pieces it can be possible to make a very flexible material. It really is practical to the installation protects that take place in a dry environment, but needs to be avoided if you have a risk of the water penetration.
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.
