Assembly and Coverings
The individual conductors are cabled together with non-hygroscopic fillers and a binder
tape overall. The C-L-X sheath exceeds the grounding conductor requirements of Table
250.122 of the NEC and UL 1569. A bare stranded copper grounding conductor(s), located in
the outer interstices, is provided for grounding. The impervious, continuous, welded,
corrugated aluminum C-L-X sheath provides complete protection against moisture, liquids
and gases and has excellent mechanical strength. For direct burial in the ground,
embedment in concrete, or for areas subjected to corrosive atmospheres, the C-L-X sheath
is protected with a low temperature black Okoseal® (PVC) jacket. Applications
C-L-X Type MC-HL cables with the impervious, continuous, corrugated aluminum sheath are
recommended as an economical alternate to a wire in conduit system.
They are authorized for use on services, feeders and branch circuits for power,
lighting, control and signaling circuits in accordance with Article 330 and 725 of the
NEC.
C-L-X Type MC-HL cables may be installed indoors or outdoors, in wet or dry locations,
as open runs of cable secured to supports spaced not more than six feet apart, in cable
tray, as aerial cable on a messenger, in any approved raceway, direct burial, or encased
in concrete. C-L-X type MC-HL cables are also approved for Classes I, II and III, Division
1 and 2, and Class I, Zone 1 and 2 hazardous locations - NEC Articles 501,
502, 503 and 505.
