Eaton HGLS9 grounding bushing - NEC/CEC certified
Part Number: HGLS9
Quick Summary
The Eaton HGLS9 grounding bushing provides a reliable ground connection for rigid/IMC conduit in control panels. Engineers often face space constraints and slow installation when wiring grounds, and HGLS9 addresses this with a compact, set-screw, threadless design. It meets NEC/CEC standards and UL certifications for ordinary locations, and brings a 150°C rating to high-heat environments. By combining an aluminum lug with a malleable iron body, this bushing delivers dependable grounding with a lighter footprint and easier service life. For automation builders and panel shops, it streamlines procurement and installation while supporting consistent electrical performance.

Eaton Specification Sheet - HGLS9
Feature: Conduit compatibility with rigid/IMC fittings lets you secure grounds in standard electrical enclosures without adapters. Business impact: accelerates installation, reduces part counts, and lowers field labor costs during panel builds. Application: ideal for automation panels, machine guard enclosures, and control cabinets where IMC or rigid conduit is used. Feature: Aluminum lug paired with a malleable iron body delivers durability without excessive weight. Business impact: easier handling during installation and improved heat dissipation, lowering shipping and inventory costs. Application: service in manufacturing lines, conveyor systems, and high-vibration environments. Feature: Threadless design plus set-screw clamping simplifies alignment and assembly. Business impact: reduces installation time, eliminates mis-threading risk, and enhances resistance to loosening in dynamic machinery. Application: space-constrained panels and retrofit projects where traditional threaded bushings are difficult to mount. Feature: Lug size #3/0-6 AWG and trade size 3-1/2" cover popular feeder conductors. Business impact: minimizes need for extra lugs or adapters. Application: panel mains, feeders to motors, and distribution blocks. Feature: 150°C temperature rating and NEC/CEC compliance. Business impact: ensures safe operation in elevated temps and simplifies code approvals. Application: non-hazardous (Ordinary) locations in automation and control environments. Feature: Compact dimensions and precise 3-1/2" trade size support compact installations. Business impact: saves enclosure space and reduces the number of bushings required. Application: dense control panels and machine enclosures in manufacturing settings.

FAQs
To install HGLS9, align the 3-1/2" trade-size body with the rigid/IMC conduit entry, insert the conductors into the aluminum lug to the #3/0-6 AWG range, and secure with the set screw. Ensure the conduit is fully seated and tightened to manufacturer torque recommendations. The threadless design simplifies alignment, reducing misfit during panel wiring and speeding up field installs.
HGLS9 supports a lug range of #3/0-6 AWG and uses a 3-1/2" trade size for the connection. This makes it suitable for common power feeders and larger motor leads in control panels. The aluminum lug paired with a malleable iron body provides both light weight and robust clamping, ensuring a solid ground path under typical industrial vibration and thermal cycling.
Yes. HGLS9 is specified for ordinary/non-hazardous locations and carries NEC/CEC standards alongside UL certifications relevant to routine industrial environments. Its 150°C rating further supports use in panels and enclosures that experience elevated temperatures, while maintaining compliant grounding performance for automation equipment.
HGLS9 complies with NEC/CEC standards for grounding bushings and holds UL certifications for non-hazardous locations. These credentials help streamline code approvals, supplier audits, and procurement processes, allowing engineers to specify with confidence in automation and distribution panel builds.
The combination of a threadless design and a set screw clamp reduces maintenance overhead by minimizing looseness and re-torquing needs in dynamic equipment. The lightweight aluminum lug plus durable malleable iron body lowers handling costs and supports long service life, contributing to lower total cost of ownership in automation projects.
