FAQs
The ECLK730 uses a 2-1/2 inch trade size and features male one end and female the other, designed to mate with common conduit fittings used in hazardous locations. Its stainless steel construction provides robust mechanical compatibility and corrosion resistance, reducing the need for adapters and simplifying field assembly.
Installers should verify NEC/CEC compliance and the Class I, Division 1 rating to ensure code conformity. Ensure proper sealing and tightening of the ends to maintain the explosion-proof integrity, and use UL-certified components in conjunction with the ECLK730 to meet certification expectations for hazardous-area equipment.
The NEC hazardous rating for the ECLK730 specifies Class I, Division 1, Class II, Division 1, and Class III, indicating suitability for multiple hazardous environments. Always confirm the exact location classification on project drawings and ensure all components in the assembly are rated for the same class/division prior to installation.
The ECLK730 carries NEC/CEC standards alignment, a Hazardous/Classified Locations area classification, and UL certifications reflected in its catalog and datasheets. These certifications validate explosion-proof performance and suitability for hazardous-area conduit connections in demanding industrial settings.
Stainless steel construction offers superior corrosion resistance, reducing maintenance frequency and downtime in harsh environments like offshore or chemical plants. The long 36-inch length minimizes joints, contributing to installation efficiency and lower lifecycle costs by decreasing potential failure points.
