Eaton Crouse-Hinds HGLL 12 250 Grounding Bushing - UL Listed
Part Number: HGLL 12 250
Quick Summary
HGLL grounding bushing is a threaded, aluminum-to-malleable-iron connector for rigid/IMC conduit in industrial electrical installations. Engineers often face grounding reliability and thermal endurance in harsh environments, which this bushing addresses with a 150°C rating and a rugged build. NEC/CEC compliance and UL certification for both US and Canada provide code confidence and safety. Designed for large-conductor connections, it supports 250 kcmil up to #6 AWG with a robust aluminum lug, enabling faster, code-compliant terminations. By combining ease of installation with durable materials, it reduces rework and warranty risk, delivering measurable efficiency gains for panel builders and field crews. Its rugged design supports fast field replacements and reduces downtime in critical projects.

Eaton Specification Sheet - HGLL 12 250
The HGLL 12 250 grounding bushing offers a compact dimensional footprint with a 7.4 in length, 5.5 in height, and 9.2 in width, which simplifies enclosure planning and mounting. This precision sizing reduces installation time and space constraints on crowded panels, enabling cleaner, code-compliant terminations in everyday plant wiring. The aluminum lug paired with a 250 kcmil-#6 AWG conductor range eliminates the need for extra adapters, lowering installation cost and minimizing resistance at the grounding path in high-current applications. A malleable iron body with threaded connections delivers enhanced mechanical strength and vibration resistance, extending service life in environments with equipment movement or shock loads. The 150°C rating ensures reliability near heat-generating equipment, while NEC/CEC compliance and UL certification provide confidence during design validation and field deployment. Overall, the HGLL 12 250 reduces rework, accelerates commissioning, and supports safer, compliant grounding of rigid/IMC installations.

FAQs
Begin by selecting a compatible rigid/IMC conduit section and ensuring the enclosure mounting area provides adequate clearance. Align the threaded HGLL bushing with the conduit opening, insert the conductor into the aluminum lug, and tighten to the manufacturer’s torque specification. Verify the lug is fully seated and that the malleable iron body is free of burrs. Use NEC/CEC guidelines to confirm grounding continuity and enclosure bonding, then test with a grounding continuity meter to validate a solid ground path.
The HGLL 12 250 supports conductors from 250 kcmil down to #6 AWG, enabling direct termination of large feeders without adapters. This wide lug size range improves installation efficiency, reduces the number of junctions, and lowers contact resistance at the grounding path, which is critical for high-current applications in industrial facilities.
Yes. The HGLL 12 250 is rated for Ordinary/Non-Hazardous locations, aligning with NEC/CEC standards for non-hazardous industrial environments. For hostile or hazardous areas, verify additional enclosure ratings and local code requirements. This bushing provides a reliable grounding connection where standard electrical installations occur, supporting consistent performance in typical plant settings.
The HGLL 12 250 carries NEC/CEC compliance and UL certifications for both US and Canada, ensuring code conformity and safety. The UL-listed status supports procurement and inspection workflows, while NEC/CEC alignment confirms that grounding connections meet widely accepted regulatory requirements across North American installations.
Maintenance-wise, the robust malleable iron body and threaded connection resist loosening under vibration, reducing rework and field service calls. From a ROI perspective, direct termination of large conductors with an aluminum lug lowers installation time and material costs, while UL/NEC/CEC compliance reduces risk of nonconformance penalties and project delays, delivering faster commissioning and safer, dependable grounding over the system’s life.
