FAQs
Install the TMCX250 2 NP L by aligning the gland with the 2-1/2" NPT threaded conduit entry, tightening to achieve the 2 (M) cable sealing range, and securing the armour with compatible seals. Ensure the cable range is within 2.24–3.28 inches and verify the assembly preserves the Liquid Compound barrier. Use recommended torque values and consult the IF 1647B instructions for step-by-step guidance to maintain NEC/CEC compliance and NEMA 4X protection.
The gland is designed for metal-clad cables with interlocked or continuously welded corrugated armoured, TECK armoured, and armoured barrier configurations. This compatibility supports tray cable installations and robust external protection, reducing the risk of abrasion or moisture ingress in harsh environments. Always confirm cable diameter falls within 2.24–3.28 inches to maintain a proper seal.
Yes. The TMCX250 2 NP L supports NEC/CEC classifications including Class I, Division 1, Class II, Division 1, and Class III, with an area classification of Hazardous/Classified Locations. It also carries a NEMA 4X rating, making it appropriate for installations in explosive atmospheres, moisture-prone areas, and industrial environments requiring stringent protection.
Constructed from nickel-plated brass, the gland uses a liquid barrier sealing approach and provides a 2 (M) cable sealing capacity. The combination of material resilience and sealing capability supports long service life in corrosive or damp environments, while maintaining reliable electrical isolation and mechanical protection for armoured cables.
Comprehensive resources include 3D CAD drawings, installation instructions (IF 1647B), brochures and catalogs, and certification reports. Access to Eaton’s specification sheets and Canadian/UL certification documents supports accurate integration, regulatory compliance, and smoother procurement in large projects.
