Eaton GLS7 250 Grounding Bushing - Rigid/IMC
Part Number: GLS7 30
Quick Summary
GLS grounding bushing provides secure grounding in rigid/IMC installations for industrial enclosures and control panels. In harsh plant environments, improper grounding can lead to faults and costly downtime. This GLS7 250 is NEC/CEC compliant and UL-listed for rigid-IMC use, with ordinary/non-hazardous location classifications, ensuring robust performance where reliability matters. The combination of an aluminum lug, 105°C rating, and threadless design delivers fast, code-compliant terminations, while keeping total installed cost in check. Secondary benefits come from its lightweight lug and durable malleable iron body, which support scalable installations across a variety of panel and conduit configurations.

Eaton Specification Sheet - GLS7 30
Feature → Business Impact → Application: The GLS7 250 uses a rigid/IMC conduit compatibility with a threadless lug, enabling rapid, mistake-free terminations that cut installation time and labor costs on large projects. This directly boosts field productivity and reduces commissioning delays in industrial facilities where reliability and speed matter. Application sees use in control panels and equipment racks that require robust, code-compliant grounding for large conductors up to 250 kcmil and #6 AWG, making it ideal for retrofit projects and new builds alike. Feature → Business Impact → Application: Aluminum lug construction lowers weight and material costs while maintaining durable electrical connection under 105°C. This improves handling during installation and reduces thermal stress in hot environments, supporting longer service life in motor controls and distribution panels. Application includes high-heat industrial settings where lightweight components and dependable heat tolerance are critical. Feature → Business Impact → Application: Malleable iron body provides mechanical strength and impact resistance, reducing risk of deformation in dense conduit runs. This supports long-term reliability in rugged production lines and outdoor installations where vibration and minor impacts are common. Application spans mining, manufacturing, and chemical processing facilities requiring durable grounding bushings. Feature → Business Impact → Application: Threadless design eliminates issues associated with threaded fittings, improving consistency of conductor clamping and reducing rework due to cross-threading. This translates to lower maintenance costs and more predictable performance in high-volume electrical builds. Application covers utility, data center, and process automation environments where repeatable, fast terminations are essential. Feature → Business Impact → Application: NEC/CEC compliance and UL certification provide regulatory assurance and simplify audits, helping suppliers meet project specifications and reduce change orders. This is especially valuable for OSHA-regulated facilities and cross-border builds in North America. Application includes hospitality, healthcare, and industrial automation projects requiring strict grounding standards.

FAQs
Install the GLS7 250 by aligning the conduit with the rigid/IMC opening, seating the aluminum lug to the conductor ends, and using approved clamps or connectors designed for a threadless lug. Ensure the lug grip is secure and torque is not required since the design is threadless. Verify the assembly is clean, free of debris, and within the 105°C rating for enclosed spaces. This reduces mis-threading risk and speeds up field terminations without compromising grounding integrity.
The GLS7 250 supports a lug range of 250 kcmil to #6 AWG, enabling large power conductors in a single grounding connection. This makes it suitable for high-capacity motor feeders and feeder bus connections in industrial control panels where robust, low-resistance grounding is required.
No. The GLS7 250 is rated for Ordinary/Non-Hazardous Locations per its area classification. For hazardous environments, select a grounding bushing with the appropriate certifications and enclosure protection (e.g., explosion-proof variants) that meet your exact safety standards.
The GLS7 250 adheres to NEC/CEC standards and is UL-listed for Rigid-IMC installations. It carries a 105°C temperature rating and uses a malleable iron body with an aluminum lug, providing reliable performance in code-compliant, North American electrical installations.
The threadless lug eliminates thread alignment issues, reduces rework, and speeds up field terminations. This translates to shorter installation windows, lower labor costs, and faster project completion, offering a favorable return on investment for large-scale automation and electrical distribution projects.
