Eaton Crouse-Hinds HGLL4 10C Grounding Bushing - 150°C
Part Number: HGLL4 10C
Quick Summary
HGLL4 10C grounding bushing securely connects copper lugs to rigid/IMC conduits, delivering a reliable grounding path in industrial installations. In demanding environments, a marginal ground path can trigger overheating, arcing, and non-compliance, leading to costly rework and downtime. This grounding bushing carries NEC/CEC standards and Canadian certification, with an area classification for Ordinary/Non-Hazardous Locations, ensuring safe and code-compliant operation. The design uses a copper lug, threaded connection, and a malleable iron body for durability, while the 1-1/4 inch trade size and lug size of #1/0-8 AWG support a wide range of feeders. By combining rugged construction with straightforward installation, it helps procurement teams improve on-site reliability and reduce inventory complexity for rigid/IMC conduit assemblies.

FAQs
HGLL4 10C supports rigid/IMC conduit with a threaded connection and a copper lug sized for #1/0-8 AWG. The trade size is 1-1/4", and the body is made of malleable iron, delivering a secure, high-current grounding path suitable for industrial panels and equipment.
The HGLL4 10C is designed to meet NEC/CEC standards and carries Canadian certification data. It is rated for ordinary/non-hazardous location use, and the copper lug plus malleable iron construction supports compliant, durable grounding connections in North American installations.
With a threaded connection and copper lug, HGLL4 10C offers straightforward mounting, reduced torque loss, and a reliable ground path. This minimizes commissioning time, lowers field rework, and improves long-term grounding stability in control panels and electrical enclosures.
No. The HGLL4 10C is specified for Ordinary/Non-Hazardous Locations, so it should be used in environments that do not require explosion-proof or otherwise hazardous location ratings.
The rugged malleable iron body, high-temperature rating, and copper lug reduce maintenance and replacement costs while improving reliability. Standardized dimensions and NEC/CEC compliance streamline procurement, installation, and regulatory approval, delivering measurable savings over the equipment lifecycle.
