Copperweld® Metal-Clad (MC) Cable is a cost-stable, energy-efficient alternative to wiring methods such as conductors in conduit and cable tray.
Copperweld® MC Cable is manufactured to UL standards and complies with the National Electrical Code (NEC). When sized appropriately according to the NEC, it has the lowest voltage drop of the three branch circuit conductor material alternatives. Disincentivizing pilferage and theft, it offers thieves only a small fraction of the scrap value of single-metal copper scrap.
Copper-Clad Aluminum (CCA) Conductor — Drawn from a copper-clad aluminum rod, with the copper metallurgically bonded to an AA 8000 series aluminum core, where oxygen-free copper forms a minimum of 10 percent of the cross-sectional area of a solid conductor or each strand of a stranded conductor.
Application Standards — UL 1569
Conductors — For wire sizes 12-10, solid annealed THHN Copper-Clad Aluminum with solid Copper Clad Aluminum ground. For 8 AWG sizes and larger, stranded annealed THHN Copper-Clad Aluminum with solid Copper-Clad Aluminum ground.
Conductor Insulation — Type THHN or THWN-2 with a heat-stabilized Nylon jacket rated for 75°C in wet locations and 90°C in dry locations.
Grounding Conductor — For NM-B 12-10 AWG sizes: ground will be 12-10 AWG, solid, annealed conductor. For NM-B 8 AWG sizes and larger: ground will be 8 AWG, solid, annealed.
Metal-Clad Jacket — Lightweight steel or aluminum interlocking armor
Copperweld® Copper-Clad Aluminum Type MC (Metal-Clad cable) is referenced by Article 330 of the National Electrical Code. OSHA safety listed: UL E523379. ETL listing: 5021266.
Identified for use with Wiring Devices, Splice Connectors and Equipment Terminals Rated for Cu, Cu/Al and CO/ALR. Copperweld® MC Cable is NRTL listed for safety. It is made with ASTM B-566 Copper-Clad Aluminum bare Copperweld® wire, which carries its own component listing, RU DVVU2. Copperweld MC conductors are suitable to terminate on 15 and 20 ampere rated wiring devices (receptacles and snap switches) marked ‘copper only’ or ‘CO/ALR’. For termination on devices rated 30 amperes or greater, the termination must be marked ‘CU/AL’ or equivalent. Please consult UL Product IQ guide information RTRT and WJQR if further confirmation is required. Copperweld® MC Cable may be pigtailed to single-metal copper wire in dry or wet locations with terminals and connectors specified for such use. Copperweld® MC Cable should not be terminated with single-metal Aluminum wire without the application of an oxide inhibitor or a terminal or connector specifically listed for such use. Copperweld® ASTM B-566 Copper-Clad Aluminum wire is not dissimilar to copper, brass or zinc plated steel.
