Insulation
X-Olene® is Okonite's trade name for its chemically cross-linked polyethylene, with high dielectric strength.
Color Coding
Conductors 6 AWG and smaller are color coded black, red, blue, orange. Power conductors #4 AWG and larger are printed number/color coded. Control conductors are color coded black, red, blue, yellow. When the control conductors are within one standard AWG size of the power conductors, the control conductors have an additional tracer to facilitate identification
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 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 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 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 cables are also approved for use in Class I & II, Division 2, Class III, Divisions 1 and 2 and Class I, Zone 2 hazardous locations — NEC Articles 501, 502, 503 and 505.
