FAQs
Install by positioning the conduit into the 4" trade-size body, align the copper lug with the conductor, and secure with the set screws. Ensure clean contact between lug and conductor, then tighten to the recommended torque per conductors size as per site standards. The threadless design simplifies alignment in tight spaces and reduces rework during panel assembly.
The HGLS10C supports a copper lug for #3/0-6 AWG conductors, enabling robust, low-resistance grounding connections for large feeders and switchgear in industrial panels.
Yes. The unit is rated for Ordinary/Non-Hazardous Locations and complies with NEC/CEC standards, making it appropriate for general-purpose grounding in typical industrial environments.
It carries NEC/CEC compliance and UL Canada certification for Rigid-IMC grounding bushings, with additional documentation available via downloadable reports and spec sheets from Eaton.
Durable malleable iron construction paired with a copper lug provides long-term grounding reliability, reducing corrosion-related maintenance. The threadless, set-screw design accelerates installation, lowers field labor time, and minimizes rework in panel upgrades.
