Eaton HGLL1C Grounding Bushing - Threaded 1/2 in - NEC/CEC
Part Number: HGLL1C
Quick Summary
HGLL1C grounding bushing provides a reliable ground path for rigid/IMC conduit installations in industrial panels and enclosures. Engineers frequently face inconsistent grounding and corrosion resistance in tight control cabinets, leading to safety and downtime concerns. This part aligns with NEC/CEC standards and is approved for Ordinary/Non-Hazardous Locations, with a robust 150°C rating for high temperature environments. The copper lug supports 4-14 AWG conductors and a 1/2 in trade size, simplifying wiring and reducing assembly time. Built from malleable iron, it combines durability with ease of OEM integration, helping maintain continuity across assemblies and improving overall system reliability for OEMs and end users.

FAQs
Yes. HGLL1C is designed for rigid IMC conduit with a threaded connection and supports copper lug connections for 4-14 AWG conductors. Follow the manufacturer installation sheet to align threading, secure the connection, and ensure a solid ground path within panels or enclosures. Use proper mounting hardware and verify the ground continuity after assembly.
Key specifications include a 1/2 in trade size, threaded connection, copper lug for 4-14 AWG conductors, and a 150°C temperature rating. It is intended for ordinary/non-hazardous locations under NEC/CEC standards, providing a low impedance ground path in rigid IMC installations and facilitating compliant panel grounding.
HGLL1C is specified for Ordinary/Non-Hazardous Locations per NEC/CEC. It is not intended for use in hazardous or explosion-prone environments without additional protective measures or certification. For outdoor or harsh environments, ensure enclosure protection and consider appropriate environmental ratings and compliant grounding bushings.
The HGLL1C family complies with NEC/CEC standards for general industrial grounding. Canadian certification references are available within the downloadable certification reports, and the datasheet confirms a 150°C rating and copper lug construction for reliable grounding across standard manufacturing facilities.
Durable malleable iron construction, copper lug with a low impedance ground path, and a high temperature rating reduce maintenance cycles and downtime. The standardized 1/2 in thread and 4-14 AWG compatibility streamline procurement and OEM integration, delivering predictable installation times and long-term cost savings across projects.
