Threaded HGLL8C design enables secure, vibration-resistant ground bonds for rigid/IMC conduits, reducing loosening risks and maintenance in high-cycle panels. This translates to fewer field service calls and improved uptime in manufacturing lines and process plants. The copper lug supports #1/0-8 AWG conductors, delivering low contact resistance and enabling reliable grounding even with larger gauge cables. The malleable iron housing with a 150°C rating provides rugged durability in harsh factory environments, improving service life and lowering replacement costs. With a 3" trade size and 4" length, installation aligns with standard enclosure footprints, simplifying retrofits and new builds alike. NEC/CEC compliance and UL certification ensure regulatory compliance and broad market acceptance, minimizing procurement risk and accelerating project timelines.

FAQs
HGLL8C is designed for threaded connection to rigid/IMC conduits and accepts #1/0-8 AWG conductors through a copper lug. Its malleable iron housing provides rugged support, while the 3" trade size and 4" length standardize mounting in common enclosures. When installing, ensure the lug is torqued to the specified range and that the conduit alignment preserves grounding integrity, especially in high-vibration environments.
Key performance specs include a threaded connection, copper lug rated for #1/0-8 AWG, 150°C temperature rating, and a malleable iron body rated for robust mechanical stability. The 3" trade size and 4" depth support consistent installation and minimize resistance paths. Together, these features deliver low contact resistance, durable bonding, and reliable operation in industrial equipment and control panels.
HGLL8C is classified for Ordinary/Non-Hazardous Locations, aligning with NEC/CEC requirements for standard industrial environments. While ideal for many panels and enclosures, it is not specified for hazardous locations. For hazardous-area applications, consult alternative products with appropriate certification and ratings. Always verify location classifications on project specifications before installation.
Documentation includes NEC/CEC compliance statements, UL certifications for rigid-IMC grounding bushings, and catalog/datasheet resources. Access to the Crouse-Hinds grounding bushings catalog page and Eaton specification sheet is provided to support design reviews and procurement. CAD drawings are also available, facilitating accurate integration into panel layouts and BIM workflows.
The robust threaded design, copper lug, and high-temperature rating reduce loosening and contact resistance, lowering maintenance frequency and unplanned downtime. Durable malleable iron housing resists wear in harsh environments, extending service life. Reduced field repairs, faster installs, and SEL (slower equipment life-cycle) costs contribute to a favorable ROI over the asset life, especially in high-duty duty-cycle panels and motor control centers.
