Eaton Crouse-Hinds HGLL 12 Grounding Bushing - NEC/CEC
Part Number: HGLL 12
Quick Summary
HGLL 12 grounding bushing provides a robust grounding path for rigid/IMC conduits in industrial enclosures. In demanding environments, improper grounding can cause intermittent faults, overheating, and downtime, which this bushing helps prevent with a secure threaded connection and durable aluminum lug. It is designed to meet NEC/CEC standards and UL certification for reliable, code-compliant installations, and is suitable for ordinary/non-hazardous locations at up to 150°C. By using this bushing, engineers can simplify field wiring, reduce maintenance cycles, and ensure consistent performance across control panels and equipment enclosures. This translates to faster commissioning, fewer re-works, and a clearer path to regulatory compliance and long-term reliability.

FAQs
Installation begins with selecting the correct 6" trade size and ensuring the conduit threads are clean and aligned. Mount the grounding bushing to the enclosure or conduit body, thread the IMC/conduit into the bushing, and terminate the #3/0-6 AWG conductors to the aluminum lug. Tighten to the manufacturer’s torque spec to ensure a secure electrical path. The threaded design provides a reliable, vibration-resistant connection ideal for industrial environments.
Key specs include a 6" trade size, threaded connection, aluminum lug for #3/0-6 AWG, malleable iron body, 150°C temperature rating, and suitability for rigid/IMC conduit. It is listed for NEC/CEC compliance and intended for ordinary/non-hazardous locations, making it a dependable choice for standard electrical enclosures and control panels.
Yes. The HGLL 12 is designed for ordinary/non-hazardous locations and complies with NEC/CEC standards. Its 150°C rating and rugged materials suit control panels, electrical cabinets, and equipment enclosures in typical industrial environments, delivering dependable grounding without special hazard considerations.
HGLL 12 adheres to NEC/CEC standards for grounding equipment. It is manufactured for Rigid/IMC conduit and carries area classification for ordinary/non-hazardous locations. UL certification resources are available for additional validation, supporting safe installation in U.S. and Canadian facilities.
The combination of a robust malleable iron body and aluminum lug provides durable, long-lasting terminations that resist corrosion and thermal stress. This reduces field maintenance, minimizes downtime, and lowers total cost of ownership by decreasing replacement frequency and rework in demanding industrial environments.
