Eaton Crouse-Hinds HGLS3C Grounding Bushing - NEC/CEC
Part Number: HGLS3C
Quick Summary
The Eaton Crouse-Hinds HGLS3C grounding bushing provides a robust grounding connection for rigid/IMC conduit in control panels, enclosures, and industrial equipment. Installation challenges like misalignment and unreliable grounds are common; this threadless, set-screw design reduces rework and ensures a secure copper-lug termination even in tight spaces. It is designed to meet NEC/CEC standards and is suitable for ordinary/non-hazardous locations, with a 150°C rating that supports demanding environments. The product’s copper lug and malleable-iron body deliver durable performance, while its 1" trade size aligns with standard conduit configurations. For manufacturers seeking compliant, reliable grounding in high-temperature applications, this bushing provides clear value and straightforward installation.

FAQs
HGLS3C is designed for 1 inch trade size rigid or IMC conduit. It uses a threadless design with a set-screw connection and a copper lug capable of accommodating #4-14 AWG conductors, making it compatible with standard conduit runs in control panels and industrial enclosures.
The grounding bushing features a malleable iron body with a copper lug. It is rated for up to 150°C, enabling reliable grounding in high-heat areas such as near motor drives or transformers, while maintaining mechanical durability in harsh environments.
Yes. The HGLS3C is manufactured to NEC/CEC standards and is appropriate for ordinary/non-hazardous locations, providing regulatory compliance for common industrial installations and simplifying approvals for panel and enclosure projects.
The threadless design with a set screw reduces misalignment and cross-threading, while the copper lug ensures low-resistance grounding. For vibration-heavy environments, ensure a secure set-screw torque and proper conductor seating to maintain reliable ground paths over time.
Using HGLS3C can lower maintenance costs due to durable copper lug grounding and high-temperature performance, and reduces installation time thanks to its threadless design. In retrofit projects, its compatibility with existing 1" rigid/IMC layouts supports rapid upgrades with minimal rewiring and downtime.
