Searching to purchase the best corrugated flexible conduit? Here are some tips and extra details helping you to make the best pick. Electrical nonmetallic tubing (ENT) is flexible corrugated plastic tubing that is moisture-resistant and flame-retardant. It is easy to bend and installs with snap-lock or glued plastic fittings. Unlike EMT, non-metallic tubing cannot installed in exposed locations, so it is commonly used inside walls. In addition to installation in standard wood- or metal-frame walls, ENT can be installed inside concrete block structures and can be covered with concrete. Due to the blue color of one common brand of this conduit, ENT is nicknamed “smurf tube,” after the Smurfs cartoon characters.
RMC and IMC can be used interchangeably, with IMC more common these days because it’s lighter and somewhat easier to work with than RMC. They are permitted for use by the NEC in dry, wet and corrosive locations and can be buried in many applications. They typically are joined with threaded connectors and fittings.
Thin-wall conduit is sold in ten-foot lengths in either one-half inch or three-quarter inch (outside) diameter. The one-half inch conduit can contain four No. 14 wires or three No. 12 wires. Three-quarter inch conduit accommodates four No. 10 or five No. 12 wires. These wire capacities are for individual wires, not pairs. The wires used are the same as the individual conductors found in steel armor cable and plastic sheathed cable. Wires in conduit must follow standard coding. In a two-wire electrical circuit you need one black wire, one white wire, and one ground wire. Discover more information on SS flexible 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.
There are strict regulations in dealing with the fill factor. A cross-sectional area of the conductors inserted would be measured and the code would determine the percent of conduit which could be filled. A conduit can never be filled 100 percent as it is not safe. The code has determined how wires and bundles of wires can safely run through a given flexible conduit. The table does not address any difference in high or low voltage cables so you can apply the table for both uses. Have this information readily available when shopping for conduits.
