FAQs
For proper installation, align the threaded HGLL 11 250 with the conduit hub, tighten to specification using appropriate wrenches, and ensure the aluminum lug is fully seated on 250 kcmil–#6 AWG conductors. Use listed torque values from the Eaton datasheet and verify a secure ground path before energizing equipment.
HGLL 11 250 supports rigid/IMC conduit, uses an aluminum lug for large conductor terminations up to 250 kcmil or #6 AWG, features a threaded connection, and has a 150°C temperature rating. It’s intended for ordinary/non-hazardous locations and complies with NEC/CEC standards with UL certification.
Yes. The HGLL 11 250 grounding bushing is UL certified and NEC/CEC compliant, designed for ordinary/non-hazardous locations. This certification simplifies compliance during audits and supports procurement in regulated industries, reducing risk and review time in project approvals.
Best used in control panels, switchgear enclosures, and industrial installations that employ rigid/IMC conduits with large conductors. The 5" trade size and aluminum lug support 250 kcmil up to #6 AWG, making it ideal for high-current grounding paths in power distribution, machine automation, and outdoor equipment.
The combination of a threaded connection, aluminum lug, and rugged malleable iron body reduces installation time and maintenance costs while delivering a durable, compliant grounding solution. UL/NEC/CEC certification accelerates procurement and commissioning, contributing to reduced project risk and longer service life in critical electrical installations.
