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.

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.
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.
