Eaton Crouse-Hinds HGLS10 250 Grounding Bushing - Threadless
Part Number: HGLS10 250
Quick Summary
The Eaton Crouse-Hinds HGLS10 250 grounding bushing provides a reliable termination for rigid/IMC conduit installations. This addresses the pain point of misaligned, threadless terminations that complicate high-current grounding in field installs. It carries NEC/CEC standards, an area classification of Ordinary/Non-Hazardous, and a 150°C temperature rating for harsh environments. Designed for rigid/IMC conduit with an aluminum lug and 4" trade size, this solution speeds assembly while delivering reliable grounding and compliance. In critical electrical installations, the simplicity of a threadless design reduces field rework and minimizes downtime, while the high-temperature rating supports diverse industrial environments. For engineers and procurement teams, it combines operational safety with predictable lead times and documented NEC/CEC compliance.

FAQs
Begin by preparing the rigid/IMC conduit end and the 250 kcmil-#6 AWG conductor. Align the bushing onto the conduit, ensuring the aluminum lug seats flush. Since this is a threadless design with a set screw, tighten the set screw firmly to secure the lug. Verify the conductor entry, tighten torque to recommended spec, and perform a continuity test to confirm a solid grounding path.
The HGLS10 250 supports a lug range of 250 kcmil-#6 AWG, uses an aluminum lug, is threadless, and is rated up to 150°C. It is designed for rigid/IMC conduit with a 4" trade size, weighs about 1 lb, and measures 5.6 in by 7.8 in by 6 in. The unit complies with NEC/CEC standards and is suitable for Ordinary/Non-Hazardous locations.
Yes. The grounding bushing is certified for Ordinary/Non-Hazardous locations per area classification and adheres to NEC/CEC standards. This makes it suitable for non-hazardous industrial environments where reliable grounding and regulatory compliance are priorities, while still delivering high-temperature performance and durable construction.
The HGLS10 250 employs NEC/CEC standards for North American electrical installations and is documented for Ordinary/Non-Hazardous area classifications. Downloadable UL certification references are available for US and Canada, supporting compliance claims. Ensure your site references the listed catalogs and datasheets during approvals and QA checks.
The malleable iron body with an aluminum lug offers robust mechanical durability and stable conductivity, reducing corrosion-related maintenance. The threadless design speeds field assembly and minimizes rework, lowering labor costs and downtime. High-temperature rating (150°C) extends service life in hotter environments, delivering a favorable return on investment through fewer replacements and simpler stocking for common 4" conduit installations.
