Eaton HGLL9C Grounding Bushing - NEC/CEC 150°C
Part Number: HGLL9C
Quick Summary
HGLL9C grounding bushing delivers robust copper lug terminations for rigid/IMC conduit in industrial electrical assemblies. Engineers often contend with loose connections, corrosion, and limited high-temperature tolerance that jeopardize uptime. This model meets NEC/CEC standards and UL listings for US and Canada, and is rated to 150°C, supporting safe operation in demanding environments. With a malleable iron body and copper lug, it provides durable, low-resistance grounding, reducing maintenance cycles and field rework. Designed for a 3-1/2 inch trade size and #3/0-6 AWG lug range, it fits standard IMC conduits and aligns with common mounting patterns. For procurement teams, this combination translates to predictable installation times, improved reliability, and cost savings across motor control centers and enclosures.

Copper lug provides low-resistance grounding for #3/0-6 AWG conductors, enabling tighter torque and reduced heat buildup in dense MCC panels, which translates to longer component life and fewer field failures. This supports safer, faster commissioning and minimizes downtime during maintenance cycles. 150°C temperature rating ensures consistent performance in high-heat environments such as motor drives and exposed industrial enclosures, reducing insulation damage risk and extending service intervals. The malleable iron body with threaded connections delivers rugged durability and vibration resistance, maintaining secure terminations in equipment subjected to frequent start‑ups and vibration, lowering rework and warranty claims. Rigid/IMC conduit compatibility and threaded design simplify installation, alignment, and field retrofit, improving first-pass fix rates and reducing on-site labor. Overall size, weight, and lug dimensions (7.5 in length, 1.5 in height, 7.4 in width, 1.26 lb; 3-1/2 in trade size) streamline cabinet planning, packing, and stock management while meeting NEC/CEC compliance and UL listings for Canada and the US.

FAQs
HGLL9C is a threaded, rigid/IMC conduit grounding bushing designed for #3/0-6 AWG lugs. To install, align the conduit, thread into the mating enclosure or fitting, and torque per Eaton’s specification sheet to ensure a secure, code-compliant connection. Confirm the trade size is 3-1/2 inches and verify copper lug seating for optimal conductivity. Always consult the product datasheet for precise torque values and recommended gaskets or seals to maintain IP and NEC/CEC compliance.
This HGLL9C model is rated to 150°C, which supports operation in high-temperature enclosures and near motors or drives. The copper lug provides low resistance and stable grounding, while the malleable iron body resists deformation under vibration. Together, these features minimize risk of thermal damage, reduce maintenance cycles, and improve overall system reliability in demanding industrial settings.
Yes. The HGLL9C grounding bushing lists area classification as Ordinary/Non-Hazardous Locations, making it appropriate for standard industrial environments. It’s designed to meet NEC/CEC standards and UL listings for US and Canada, ensuring compliant grounding in typical electrical installations without special explosion-proof requirements.
HGLL9C complies with NEC/CEC standards and is UL-listed for both the US and Canada. It features a 150°C temperature rating, a copper lug, and a malleable iron body, aligning with common industrial Anforderungen and enabling straightforward regulatory audits and quality assurance across mid- to high-volume facilities.
The copper lug and robust malleable iron body resist corrosion and loosening, reducing maintenance frequency and downtime. A reliable, threaded connection speeds up installation and future retrofits, lowering field labor costs. Over time, these factors contribute to a lower total cost of ownership by improving uptime, safety, and long-term grounding integrity.
