Overview

ABB Installation Products CMAUS14M-L is a UL Listed and CSA compliant Aluminum Flexible Metallic Conduit (FMC), also known as 'Reduced Wall' or 'Greenfield' conduit. This non-jacketed metallic conduit features a 7/16 inch conduit size, designed for universal wiring applications in commercial, industrial, and residential environments. The conduit is manufactured from aluminum, providing lightweight corrosion resistance and durability compared to steel alternatives. Supplied in a 300 meter (1,000 feet) coil, the CMAUS14M-L offers efficient handling and installation flexibility for long runs without excessive splicing. The conduit meets RoHS compliance standards, ensuring restricted substance compliance for global markets. Typical applications include machine tool wiring, control panels, lighting circuits, and equipment interconnects where vibration resistance and mechanical protection are required. The 7/16 inch size provides a balance between bend radius flexibility and physical protection for conductors up to 6 AWG. Installation is simplified using standard FMC fittings and connectors compatible with ABB’s CMAUS series. The conduit’s aluminum construction reduces weight by approximately 30% versus steel equivalents, easing handling and reducing structural load in overhead or suspended installations. Electrical continuity is maintained through the metallic construction, supporting grounding and bonding requirements per NEC Article 348. The CMAUS14M-L is ideal for environments where moderate physical protection is needed without the rigidity of rigid conduit systems.
  • UL Listed and CSA compliant for North American installations
