Eaton Crouse-Hinds HGLL 4 Grounding Bushing - 150°C
Part Number: HGLL 4
Quick Summary
HGLL 4 grounding bushing provides a reliable grounding path for rigid/IMC conduit connections in industrial electrical installations. This accessory helps electricians avoid intermittent grounding and panel faults by delivering a solid, metal-to-metal connection. The design targets ordinary/non-hazardous locations and carries a 150°C temperature rating, with a sturdy malleable iron body and an aluminum lug for corrosion resistance. It complies with NEC/CEC standards and is UL-listed for Canada, offering confidence during cross-border projects. For buyers, this means faster installation, fewer field reworks, and long-term reliability in heat-intensive environments, all while maintaining code compliance and compact form in tight enclosures. The HGLL 4 complements other Crouse-Hinds grounding components for streamlined procurement.
