Overview

ABB CMAUS02M-L is a 1/2-inch aluminum flexible metallic conduit (Series CMAUS) designed for universal wiring applications where durable, bendable protection is required. Constructed from non-jacketed aluminum, this conduit—commonly referred to as 'Reduced Wall' or 'Greenfield'—delivers reliable mechanical protection for conductors in both indoor and outdoor environments. The conduit is UL Listed, ensuring compliance with North American safety standards for electrical installations, and meets RoHS requirements for restricted substance content in electrical and electronic products. This 300-meter (1,000-foot) spool provides long continuous runs, reducing the need for multiple joints and minimizing installation time. The 1/2-inch trade size accommodates a wide range of conductor bundles while maintaining flexibility for routing around obstructions, through tight spaces, or across vibration-prone areas such as machinery enclosures, control panels, and HVAC systems. Its metallic construction resists crushing and impact, offering superior physical protection compared to non-metallic alternatives. Ideal for use in commercial buildings, industrial facilities, data centers, and renewable energy installations, the CMAUS02M-L supports both power and control wiring where NEC or CEC compliance is required. The aluminum material provides corrosion resistance in damp or corrosive atmospheres, extending service life in harsh conditions. Installation is simplified with standard EMT fittings and compatible connectors, ensuring compatibility with existing infrastructure. Key benefits include reduced labor costs due to ease of bending and cutting, improved safety through grounded metallic shielding, and long-term reliability in dynamic or high-traffic environments. The UL listing confirms the conduit’s suitability for use in conduit systems up to 600V, making it a versatile choice for electrical contractors and system designers seeking a balance of performance, compliance, and cost efficiency.
