Insulation
X-Olene® is Okonite's trade name for its chemically cross-linked polyethylene, with high dielectric strength.

Color Coding
Conductors are color coded using base colors and tracers in accordance with the Conductor Identification Table bellow.

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. The impervious, continuous, 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 services, feeders and branch circuits for power, lighting, control and signaling circuits in accordance with Articles 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 1 and 2  hazardous locations - NEC Articles 501, 502, 503 and 505.

Authorized Stock Item - Available from our Service Centers.

* These items are not CSA Listed. CSA listing available as special order.

Length Tolerance - Cut lengths of 1000 feet or longer are subject to a tolerance of +/- 10%, less than 1000 feet, +/- 15%.

(1) Cross-sectional area for calculation of cable tray fill in accordance with NEC Section 392.9.

Jackets - Optional jacket types available - consult local sales office.

Ampacities
Ampacities are based on Table 310.16 of the National Electrical Code for XHHW-2 conductors rated 90°C, in a multi-conductor cable, at an ambient temperature of 30°C (86°F). The 75°C column is provided for additional information.

 The ampacities shown apply to open runs of cable, installation in any approved raceway, direct burial in the earth, or as aerial cable on a messenger. Derating for more than three current carrying conductors within the cable is in accordance with NEC Section 310.15.

The ampacities shown also apply to cables installed in cable tray in accordance with NEC Section 392.11.
