Searching to buy some top quality pvc coated flexible conduit? Here are some tips and extra details helping you to make the best choice.
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.
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. See extra details at Stainless flexible conduit.
Electrical metallic tubing, or EMT, is the most common type of conduit for exposed interior installations, such as in a basement or an unfinished garage or workshop. It is the lightest and thinnest of the rigid metal conduit types and comes in a few different diameters; 1/2-inch is the most standard size for household circuits. EMT is also called “thin-wall” and is relatively easy to bend with a tool called a conduit bender. EMT is permitted by the National Electrical Code (NEC) for dry and wet locations but requires special watertight fittings and connectors in wet locations. With proper installation, EMT raceway can serve as a circuit ground path and be used in place of a separate ground wire running inside the 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.
EMT is installed with couplings and fittings that are secured with setscrew or compression-type fasteners. The tubing itself is not threaded like RMC and IMC. Common sizes of EMT include 1/2-inch, 3/4-inch, and 1-inch. It is commonly used for exposed indoor wiring runs in residential and light commercial construction. If installed outdoors in exposed locations, it must be assembled with special watertight fittings.
