Eaton Crouse-Hinds RC300SA Rigid conduit coupling - NEC/CEC
Part Number: RC300SA
Quick Summary
Rigid conduit coupling joins aluminum rigid/IMC conduit in industrial electrical installations. This RC300SA solution from Eaton Crouse-Hinds addresses common field challenges like misalignment, corrosion, and unreliable fittings, helping projects stay on schedule. You need dependable code compliance; NEC/CEC standards and UL certifications provide that foundation for US and Canadian sites. In particular, the Ordinary/Non-Hazardous Locations area classification ensures suitability for typical plant environments, while the aluminum construction provides corrosion resistance with lighter handling. By combining robust performance with straightforward installation, this product lowers labor time, reduces replacement cycles, and helps maintain ongoing system integrity. For engineers and procurement teams, RC300SA also ensures compatibility with standard 3-inch conduit and existing rigid/IMC installations, supporting fast, code-aligned turn-key wiring runs.

FAQs
RC300SA is designed for aluminum rigid/IMC conduit with a 3 inch trade size. The coupling provides a secure, end-to-end connection between conduit sections; ensure the conduit ends are clean and aligned, then install the coupling per standard rigid/IMC installation practices. This minimizes misalignment and reduces rework during panel or conduit runs, delivering quicker commissioning in automation projects.
RC300SA is NEC/CEC compliant and UL-listed for Rigid-IMC applications, with area classification suitable for Ordinary/Non-Hazardous Locations. These certifications confirm code conformity and safety for US and Canadian installations, streamline inspections, and reduce risk of non-compliant rework. The UL listing also supports long-term reliability in factory environments where uptime matters.
No. RC300SA is rated for Ordinary/Non-Hazardous Locations and is intended for standard industrial environments. For hazardous or classified areas, select fittings specifically rated for those environments, and review local code requirements. The product’s aluminum construction and NEC/CEC compliance are optimized for non-hazardous service where robust, lightweight connections are needed.
RC300SA has a 3 inch trade size with a length of 3.25 inches and overall dimensions of 3.94 by 3.94 inches. The product weighs 0.91 pounds and is manufactured from aluminum. These specifications support precise fitment in constrained spaces and easy handling during installation in panel homes or equipment cabinets.
The combination of UL listing, NEC/CEC compliance, and ordinary-location suitability reduces inspection latency and rework, translating to faster project completion and lower lifecycle costs. The aluminum, lightweight construction eases field handling, while the 3 inch rugged rigid/IMC compatibility minimizes the need for additional adapters, ultimately offering lower procurement complexity and improved total cost of ownership in automation environments.
