SPEC A001 October, 2014 CCW Installation Manual ® Introduction CCW provides a unique wiring system that is unparalleled in versatility for practically every installation condition or requirement. CCW Is A Self-Contained Wiring System CCW Has Almost-Universal Applications • In cable tray, where identified for such use – see 392.10, 392.20(A), (B) and (C) • As aerial cable on Messenger- Supported Wiring or installed outside of buildings or structures – see 225.10, 396.10, and 396.12 • In any raceway • In hazardous (classified) locations Class I, Division 1 [511.7, 513.7, 515.7, and 516.7] Class I, Division 2 [501.10(B)(1) and (5)] Class I, Zone 2 [505.15(C)(1)(b)] CCW Type MC The CCW wiring system consists of conductors or a cable enclosed in a raceway consisting of a strong, pliable aluminum metallic sheath that is continuously welded to provide a completely enclosed gas/vapor- tight metallic sheath that is then corrugated. Corrugating the aluminum sheath provides greater crush and impact resistance for mechanical protection of the conductors and increases the pliability of the cable during installation. The standard corrugated aluminum sheath used on all CCW cables complies with the more severe crush and impact requirements of UL 2225 for HL cables permitted in hazardous locations. CCW Type MC Metal-Clad Cable has been installed in some of the most demanding applications for over 40 years and has become an industry standard for industrial and commercial applications. CCW is available in low- and medium- voltage power, control, signal, and instrumentation cables. As CCW is rated MC-HL, it can be used in any Type MC application, as it complies with UL 1569, Metal-Clad Aluminum Cable. CCW has been recognized by the National Electrical Code® (NEC® ) for more than 40 years, and the permitted uses of CCW in the NEC have been significantly expanded over the years, as users have recognized the unique advantages of this factory-assembled wiring system and inspectors have observed and recognized the trouble- free performance of CCW in all the uses permitted. NEC Article 330 is the primary article for CCW Metal-Clad Type MC Cable. In accordance with this Article, CCW rated from 600 V to 35 kV is permitted to be used in the applications shown below; the additional references included refer to the 2014 NEC. • For services, feeders, and branch circuits • For power, lighting, control, and signaling circuits • As exposed runs “ER” (formerly open wiring) or concealed • Indoors or outdoors Class II, Division 2 [502.10(B)(3) and (6)] Class III, Divisions 1 and 2 [503.10(A) and (B)] Intrinsically Safe Circuits [504.20] Zone 22 [506.15(C)(3) and (6)] [Not included in UL 2225] • Special Occupancies – see Articles 517 through 552 • As Service-Entrance Cable – see 230.43 • In wet and dry locations – since the metallic covering is impervious to moisture, the insulated conductors under the metallic sheath are listed for use in wet locations, and a corrosion-resistant protective nonmetallic jacket is provided over the metallic sheath • To be direct buried or encased in concrete, since CCW has a corrosion-resistant protective nonmetallic jacket over the metallic sheath – see 300.5 or 300.50, as appropriate • As single-conductors when all the phase conductors and, where used, the neutral conductor are grouped together to minimize induced voltage on the sheath – see 300.20 Unless otherwise stated, all references refer to the 2014 NEC® .
