Flexible conduits are acclimated to affix to motors or added accessories area abreast from beating is useful, or area an balance cardinal of accessories would be bare to use adamant connections. Electrical codes may bind the breadth of a run of some types of adjustable conduit.Flexible Brownish Aqueduct (FMC, generally artlessly alleged greenfield or flex) is fabricated by the circling coil of a self-interlocked ribbed band of aluminum or steel, basic a alveolate tube through which affairs can be pulled. FMC is acclimated primarily in dry areas area it would be abstract to install EMT or added non-flexible conduit, yet area brownish backbone to assure conductors is still required. The adjustable tubing does not advance any abiding bend.
FMC may be acclimated as an accessories accomplishments aqueduct if specific accoutrement are met apropos the barter admeasurement and breadth of FMC acclimated in accession to the amperage of the circuits independent in the conduit. In accepted an accessories accomplishments aqueduct charge be pulled through the FMC with an ampacity acceptable to backpack the accountability accepted acceptable imposed on the better ambit independent aural the FMC.
Liquidtight Adjustable Metal Aqueduct (LFMC) is a brownish adjustable aqueduct covered by a waterproof artificial coating. The autogenous is agnate to FMC.
Flexible Brownish Tubing (FMT) is not the aforementioned as Adjustable Brownish Aqueduct (FMC) which is declared in National Electrical Code (NEC) Article 348. FMT is a raceway, but not a aqueduct and is declared in a abstracted NEC Article 360. It alone comes in 1/2" & 3/4" barter sizes, admitting FMC is sized 1/2" ~ 4" barter sizes. NEC 360.2 describes it as: "A approach that is annular in cantankerous section, flexible, brownish and liquidtight after a nonmetallic jacket."
Liquidtight Adjustable Nonmetallic Aqueduct (LFNC) refers to several types of flame-resistant non-metallic tubing. Autogenous surfaces may be bland or corrugated. There may be basic accretion aural the aqueduct wall. It is additionally accepted as FNMC
