Eaton Specification Sheet - HGLL 3
Rigid/IMC compatibility ensures a robust grounding path for standard industrial wiring, reducing field adjustments and torque-related lug stress for long conduit runs. This translates to fewer commissioning errors and improved reliability in control panels and machine enclosures. The 1" trade size with threaded connection simplifies installation and replacements, enabling faster field retrofits and consistent engagement with mating components in new builds and upgrades. The aluminum lug and #4-14 AWG capacity offer corrosion resistance and lightweight handling, lowering maintenance costs and easing terminal maintenance in harsh environments. A malleable iron body rated at 150°C provides durability where heat can accumulate, supporting extended service life in motor control centers and equipment housings. NEC/CEC compliance and ordinary-location suitability validate the product for standard plant environments, enabling streamlined procurement and documentation for consistent compliance.

FAQs
HGLL 3 is designed for rigid/IMC conduit with a threaded 1 inch connection. It accepts #4-14 AWG conductors via an aluminum lug and uses a malleable iron body, making it suitable for standard industrial installations using rigid conduit systems.
Key specs include a 1" trade size, threaded connection, aluminum lug for #4-14 AWG conductors, malleable iron body, and a 150°C temperature rating. It is intended for rigid/IMC conduit and complies with NEC/CEC standards for ordinary locations.
No. The HGLL 3 is certified for Ordinary/Non-Hazardous locations under NEC/CEC standards, so it should not be used in Class I/II hazardous areas unless a variant with appropriate certifications is specified.
The product alignment includes NEC/CEC compliance and UL Canadian certification validation, as reflected in Eaton’s documentation and CAD/spec sheets, ensuring North American regulatory compatibility for standard industrial environments.
Follow the Eaton HGLL 3 specification sheet for torque and termination guidance, ensure proper alignment with rigid/IMC conduits, use correct lug sizing (#4-14 AWG), and verify the 1" threaded connection. Proper installation reduces rework and improves long-term grounding reliability, delivering measurable maintenance savings.
