ARTICLE 356. LIQUIDTIGHT FLEXIBLE NONMETALLIC CONDUIT: TYPE LFNC356.2. Definition.‚ÄÉThis is a flexible nonmetallic raceway of circular cross section, available in three forms. Type LFNC-A has a smooth, seamless inner core and cover bonded together, with reinforcement between the core and cover layers. Type LFNC-B has a smooth inner surface together with reinforcement within the conduit wall. This is its most usual form. Type LFNC-C has a corrugated inner and outer surface, with no reinforcement in the wall. It is generally limited to 6 ft (1.8 m) lengths unless a longer length is required for the amount of flexibility called for at the point of use. However, the "B" style does not carry this length limitation.
