Quick Summary

The Eaton Crouse-Hinds HGLL9 250 grounding bushing provides reliable conductor grounding for rigid/IMC conduit in industrial environments. In harsh facilities, improper termination and mismatched lug sizes lead to overheating and costly downtime. It complies with NEC/CEC standards and UL certifications for Rigid-IMC installations in Ordinary/Non-Hazardous locations, with a 150°C temperature rating that supports high-heat environments. The unit’s malleable iron body and aluminum lug deliver robust mechanical strength and corrosion resistance, while accommodating a 3-1/2" trade size and a 250 kcmil-#6 AWG conductor range. This combination enables faster field assembly, reduces maintenance cycles, and improves long-term reliability for electrical distribution projects.
