Eaton Specification Sheet - HGLS 12
Rigid/IMC conduit compatibility provides a robust ground path even in vibration-prone installations, translating to reduced leakage risk and improved equipment uptime in automated systems. The threadless design simplifies installation, minimizes cross-thread damage, and lowers torque requirements, accelerating panel assembly and reducing labor costs. An aluminum lug delivers corrosion resistance and lighter weight without sacrificing conductivity, enabling easier handling and inventory management for high-volume projects. The 150°C temperature rating supports high-heat environments such as motor control centers and outdoor enclosures, maintaining insulation integrity and safety margins. Malleable iron body adds rugged mechanical strength for demanding industrial settings, improving long-term reliability in harsh environments. NEC/CEC compliance and ordinary/non-hazardous location suitability ensure code-conformant installations, helping procurement teams meet regulatory timelines with confidence. The 6" trade size and #3/0-6 AWG lug capacity align with common industrial conductor practices, streamlining sourcing and reducing mismatch risk during retrofits or new builds. This grounding bushing also pairs well with Eaton Crouse-Hinds catalog pages and specification sheets, facilitating quick reference during design reviews and field audits.

FAQs
Begin with power off and confirm conduit size. Fit the HGLS 12 onto the rigid/IMC run, insert the #3/0-6 AWG conductor into the aluminum lug, and secure with the set screw. Ensure the threadless design is properly seated to avoid binding, then torque to the manufacturer’s specifications. Verify continuity with a ground test and inspect for any loose connections during commissioning.
Key specs include: conduit type rigid/IMC, lug material aluminum, lug size #3/0-6 AWG, trade size 6 inches, threadless, set screw type, material malleable iron, and temperature rating 150°C. The product is designed for ordinary/non-hazardous locations and complies with NEC/CEC standards, with UPC 784564953766 and catalog number HGLS 12.
Yes. The HGLS 12 is rated for up to 150°C, making it suitable for high-temperature environments found in motor control centers, heated enclosures, and other industrial applications where insulation and ground integrity must endure elevated service temperatures without degradation.
The grounding bushing complies with NEC/CEC standards and is intended for Ordinary/Non-Hazardous Locations. This helps ensure regulatory alignment during design, procurement, and field installation across North American facilities. For Canada-specific certification considerations, refer to the corresponding UL listings in the connected product literature.
The HGLS 12 reduces installation time with a threadless, set-screw connection that’s easy to assemble and less prone to cross-threading. The aluminum lug lowers weight and simplifies handling, while the rugged malleable iron body improves durability in harsh environments. Together, these factors reduce field maintenance, downtime, and inventory complexity, delivering faster commissioning and lower lifecycle costs.
