FMT is a raceway, but not a conduit and is described in a separate NEC Article 360. It only comes in 1/2" & 3/4" trade sizes, whereas FMC is sized 1/2" ~ 4" trade sizes. NEC 360.2 describes it as: "A raceway that is circular in cross section, flexible, metallic and liquidtight without a nonmetallic jacket."
Fill capacity is provided for furniture systems. Fill capacity is provided for perimeter raceways. Design requirements for poke-thru fittings. Access floor heights are adjusted. In-floor systems include underfloor duct and cellular raceways. Pathway fill is provided for cable tray. A discussion of telecommunications diversity has been added.
The NEC specifies acceptable numbers of conductors in crowded areas such as inside conduit, referred to as the fill rating. If the accepted fill rating is exceeded, then all the cables in the conduit are derated, lowering their acceptable maximum ambient operating temperature. Derating is necessary because multiple conductors carrying full-load ...
Since flowable fill is normally a comparatively low-strength material, there are no strict quality requirements for fly ash used in flowable fill or controlled low strength material mixtures. Fly ash is well suited for use in flowable fill mixtures. Its fine particle sizing (nonplastic silt) and spherical particle shape enhances mix flowability.

Students attending the Electrical Practices and Standards classes are taught the National Electrical Code and conduit bending. Students learn to calculate bend radius, conductor size, conductor type for a specific location, circuit protection, box fill and maximum number of conductors in a raceway.
Cable trays are used as an alternative to open wiring or electrical conduit systems, and are commonly used for cable management in commercial and industrial construction. They are especially useful in situations where changes to a wiring system are anticipated, since new cables can be installed by laying them in the tray, instead of pulling ...
