FAQs
Installation follows standard conduit sealing practices with the included gasket and locknut. Verify hub sizes (2 in female, 2-1/2 in male), select compliant conduit fittings, and follow the IF 1728 installation sheet for hazardous area assemblies. Ensure consistent torque on locknut and perform a post‑install ingress check to confirm a proper seal against moisture, dust, and arc‑tracking risks.
ES76 SG features a 2 inch female hub and a 2-1/2 inch male hub, engineered from Feraloy iron alloy for high strength and corrosion resistance. The unit includes a sealing gasket and locknut, enabling reliable installations in harsh environments. This combination supports robust mechanical compatibility with common conduit systems in hazardous locations.
Yes. ES76 SG is designed for hazardous/classified locations and is rated for Class I Division 1 and Division 2, aligning with NEC/CEC standards. This helps ensure code compliance, safer operation, and easier approval in refineries, chemical plants, and other hazardous facilities where sealing integrity is critical.
ES76 SG is supported by NEC/CEC compliance and hazardous location certifications. Eaton provides installation instructions IF 1728, a product specification sheet, and Canadian certification references in its downloads. These documents aid in regulatory validation, quality assurance, and audit readiness for cross-border projects.
The ES76 SG reduces lifecycle costs through fewer adapters, faster commissioning, and longer service life thanks to its Feraloy alloy and reliable gasket/locknut seal. Reduced maintenance downtime and improved ingress protection translate to lower total cost of ownership in oil & gas, chemical processing, and mining facilities, delivering measurable uptime and procurement efficiency.
