FAQs
RC400SA is designed for aluminum rigid/IMC conduits and features a 4 inch trade size with a 3.5 inch depth compatible with standard enclosures. It provides a secure, vibration-resistant joint that simplifies field assembly and reduces the risk of misalignment or leaks during commissioning. Ideal for control panels and equipment housings in industrial plants.
Key performance specifications include aluminum material, rigid/IMC conduit compatibility, 4 inch trade size, 3.5 inch product length, and a 5 inch footprint for straightforward installation. Weight is approximately 1.42 lb. Catalog number RC400SA and UPC 662276484009 accompany NEC/CEC compliance for reliable North American use.
RC400SA is approved for Ordinary/Non-Hazardous Locations, aligning with NEC/CEC standards for general industrial environments. It is not rated for hazardous or classified locations. This makes it a cost-effective, compliant choice for standard manufacturing floors, control rooms, and machinery housings where exposure is typical but non-explosive.
RC400SA carries NEC/CEC compliance and UL Canadian certification documentation for rigid-IMC fittings. This certification package supports cross-border installations and helps ensure regulatory alignment in North American facilities, reducing procurement and compliance risk during audits or inspections.
Using RC400SA can lower maintenance downtime through a secure, corrosion-resistant aluminum joint that resists wear and moisture. Faster installation reduces commissioning time, while predictable performance lowers spare parts and service costs. Collectively, these factors contribute to improved uptime and a lower total cost of ownership in high-volume production environments.
