Eaton Crouse-Hinds HGLL8 250 Grounding Bushing - NEC/CEC
Part Number: HGLL8 250
Quick Summary
HGLL8 250 grounding bushing provides a reliable grounding path for rigid/IMC conduit in industrial installations. Engineers often face lug compatibility challenges and overheating in compact control panels, which can slow commissioning. It meets NEC/CEC standards and UL certifications for Rigid-IMC fittings in ordinary/non-hazardous locations, giving assurance of compliance. With an aluminum lug rated for 250 kcmil through #6 AWG and a 150°C rating, it simplifies procurement while delivering robust performance. Its 3" trade size, malleable iron body, and a 6 in length support clean, space-efficient installs—reducing labor and field rework. This combination helps reduce maintenance costs and ensures reliable safety grounding across demanding environments.

Eaton Specification Sheet - HGLL8 250
Feature: Conduit compatibility with rigid/IMC fittings and a threaded connection. Business Impact: Ensures a solid ground path with fewer field splices and minimized heat buildup, boosting system reliability and reducing troubleshooting time. Application: Ideal for control panels, MCCs, and equipment rooms in manufacturing environments where durable grounding is essential. Feature: Malleable iron body with an aluminum lug. Business Impact: Combines structural strength with corrosion resistance and lighter weight, extending service life in high-temperature applications. Application: Suitable for industrial automation gear and outdoor-rated enclosures that see thermal cycling up to 150°C. Feature: Lug size and conductor range 250 kcmil–#6 AWG. Business Impact: Enables direct termination of large feeders, reducing the need for splices and adapters while supporting high-current grounding paths. Application: Feeder connections in switchgear, motor control centers, and main distribution panels. Feature: Temperature rating of 150°C. Business Impact: Maintains mechanical integrity and electrical performance in hot environments near equipment like drives and heat-generating machinery. Application: Plants with elevated ambient temperatures or proximity to heat sources. Feature: Physical dimensions and weight (6 in length, 4 in height, 1 in width, 0.81 lb). Business Impact: Small footprint simplifies installation in tight spaces and accelerates mounting in dense electrical racks. Application: Control cabinets, junction boxes, and confined conduit runs where space is at a premium. Feature: Compliance and certifications ( NEC/CEC, Ordinary/Non-Hazardous Locations, UL-listed). Business Impact: Supports regulatory adherence and audit readiness, reducing risk and accelerating project approvals. Application: Industrial facilities requiring standard grounding fittings that meet regional electrical codes.

FAQs
HGLL8 250 uses a threaded connection to mount on rigid or IMC conduit. Follow standard grounding bushing installation practices, align the aluminum lug with the conductor, and refer to the Eaton HGLL8 250 specification sheet for torque values. The assembly supports conductors up to 250 kcmil through #6 AWG, with a 3" trade size. Ensure the area classification is suitable for ordinary/non-hazardous locations.
The lug accepts conductors ranging from 250 kcmil down to #6 AWG, using an aluminum lug. This size range enables direct grounding connections for large feeders and control circuit conductors, reducing the need for additional adapters and splices in most industrial installations.
Yes. The HGLL8 250 grounding bushing is designed to meet NEC/CEC standards and is UL-listed for Rigid-IMC fittings in ordinary/non-hazardous locations. This ensures regulatory compliance for widespread industrial applications and supports safe, code-conforming grounding installations.
HGLL8 250 has a length of 6 inches, height of 4 inches, and width of 1 inch, with a weight of 0.81 pounds. It features a malleable iron body and an aluminum lug, designed for a 3 inch trade size and threaded connection, suitable for space-constrained panels.
Common applications include grounding connections for rigid/IMC conduit runs in control panels, MCCs, and switchgear within manufacturing plants and process facilities. Its 150°C rating and large conductor compatibility support reliable grounding under elevated temperatures, while NEC/CEC compliance and UL listing streamline regulatory approvals for non-hazardous environments.
