FAQs
Install with the conduit ends in male/female configuration as labeled, ensuring each end mates securely to the respective conduit fittings. Verify 3/4 in trade size compatibility, maintain proper electrical continuity, and follow NEC/CEC guidelines for Class I, Division 1 classifications. Ensure the assembly remains sealed and check for any signs of damage before energizing.
Yes. The ECLK227 is designed as part of the EC Explosionproof family and uses a 3/4 in trade size with forged brass construction, providing reliable compatibility with standard EC conduit fittings and enclosure interfaces used in hazardous locations.
Best suited for hazardous-area installations in chemical plants, oil and gas facilities, marine environments, and other areas requiring NEC/CEC compliance with Class I, Division 1 (and Class II/III) protection. The 27 in flexible length supports complex routing while maintaining a sealed connection.
The ECLK227 carries NEC/CEC standards, Hazardous/Classified Locations area classification, and NEC hazardous ratings including Class I, Division 1, Class II, Division 1, and Class III, with UL certifications for explosionproof use. These certifications support safe operation in regulated facilities and simplify audits.
The forged brass construction and robust sealing reduce corrosion-related downtime and maintenance costs. The 27 in flexible length lowers the number of fittings required, speeding installation and reducing field assembly risk in hazardous areas, contributing to lower total cost of ownership and improved system availability.
