Eaton HGLL10C Grounding Bushing - Rigid/IMC 150°C
Part Number: HGLL10C
Quick Summary
HGLL10C grounding bushing provides secure copper lug termination for rigid/IMC conduits in electrical panels and enclosures. Too often field assemblies suffer from unreliable ground connections and heat rise in harsh environments. This design meets NEC/CEC standards and operates at up to 150°C, with a malleable iron housing and copper lug. For procurement teams, the HGLL10C offers consistent quality, traceable UPC, and documented installation data to streamline sourcing and QA. With copper lug compatibility for wires in the #3/0-6 AWG range and threaded connections, field installs are faster and more reliable. Its compact 4" trade size and robust malleable iron housing also resist mechanical stress in demanding industrial environments.

HGLL10C offers rigid/IMC conduit compatibility with a threaded grounding interface. This design ensures a consistent low-impedance path to earth and reduces field rework caused by mismatched fittings or missing grounds. It excels in panel boards, electrical enclosures, and industrial control cabinets where reliable grounding is critical for safety, control accuracy, and long-term equipment performance. Copper lug and lug size of #3/0-6 AWG deliver a high-current, low-resistance connection ideal for large feeders and main grounding runs. Copper contact resists corrosion and maintains a stable ground path under dynamic loads, which reduces maintenance calls and service interruptions. This configuration supports rigid/IMC installations in facilities with demanding electrical loads and frequent thermal cycling. With a 4 inch trade size and a robust malleable iron housing, HGLL10C withstands mechanical stress from vibration and impact common in industrial settings. The 150°C temperature rating supports installations near heat-generating equipment without compromising insulation or ground continuity. This combination makes it a reliable choice for equipment rooms, machine enclosures, and outdoor installations where space and heat are considerations. NEC/CEC standards compliance and ordinary/non-hazardous area classification are built into the device. This alignment reduces regulatory risk and simplifies internal audits, procurement reviews, and site approvals. Users benefit from predictable performance in non-hazardous locations across North America, enabling consistent grounding practices across multi-site deployments. The HGLL10C catalog presence and UPC enable streamlined procurement and traceability in ERP and MRP workflows. Access to official data, including 3D CAD drawings and specification sheets, accelerates engineering validation and onboarding. Standardizing on a single grounding bushing across projects lowers spare-parts complexity, minimizes stocking costs, and shortens time-to-value for uptime-sensitive systems.

FAQs
HGLL10C is designed for rigid/IMC conduit with a threaded connection, delivering a fixed grounding interface. This combination reduces field install variability and ensures consistent impedance at the termination. It is ideal for electrical panels, enclosures, and machine controls where compliant grounding is required and installed conduits must maintain mechanical integrity over time.
The HGLL10C features a copper lug rated for #3/0-6 AWG conductors, providing low resistance ground paths suitable for high-current applications. The copper-lug interface improves conductivity and resistance to corrosion, reducing maintenance needs. This makes it suitable for main grounding runs in rigid/IMC installations and large-diameter feeder connections.
Yes. HGLL10C is specified for Ordinary/Non-Hazardous Locations under NEC/CEC standards. This classification supports non-hazardous environments typical of many manufacturing and process facilities. It helps streamline approvals and QA processes while delivering reliable grounding performance across standard industrial settings.
HGLL10C complies with NEC/CEC standards and is listed for ordinary non-hazardous locations. It is documented with UPC and has downloadable certification assets, including Canadian certification references and specification sheets. These certifications support regulatory compliance, supplier audits, and cross-site procurement programs.
By delivering a threaded, copper-lug ground connection with 150°C rating in a compact malleable-iron housing, HGLL10C reduces field rework, heat-related grounding concerns, and early part failures. Standardized lug size and availability of CAD drawings and catalogs simplify procurement and engineering validation, lowering stocking costs and accelerating time-to-value for uptime-critical systems.
