Type MC
Cu-Clad Conductor

600 V  |  Premium Building Wire

The Copperweld® Metal-Clad (MC) Cable Advantage

Copperweld® Metal-Clad (MC) Cable is a cost-efficient alternative to pipe and wire systems, especially when installing in commercial buildings and places of large public assembly. Copperweld® MC Cable offers unsurpassed reliability, provides greater resistance to mechanical damage, permits design flexibility of cable runs, and simplifies cable rerouting for equipment relocation. The cable handles power, lighting, control and signal circuits. It is ideal where space is limited. Size for size, Copperweld® is three times lighter than standard copper MC Cable.

Product Overview


Cu-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 Standard — 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

Theft Deterrent

Metallugically bonded conductor results in lower scrap value, reducing theft.

Energy Efficient

Better energy efficiency than standard residential branch circuit wiring.

Cost Stable

Reduced exposure to commodity fluctuation improves your bottom line.

Identification, Applications and Usage

Copperweld® Copper-Clad Aluminum Type MC (metal-clad cable) is referenced by Article 330 of the National Electrical Code. ETL listing: 5021266.

Identified for use with Wiring Devices, Splice Connectors and Equipment Terminals Rated for Cu, Cu/Al and CO/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® CCA conductors satisfy Article 110.14 Electrical Connections as being a similar metal to copper for the purposes of electrical connections. 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.
