Eaton Crouse-Hinds HGLS1 grounding bushing - 150°C
Part Number: HGLS1
Quick Summary
Eaton Crouse-Hinds HGLS1 grounding bushing is a rugged, threadless fitting designed to bond rigid/IMC conduit in electrical enclosures. Installers often face time-consuming threading and inconsistent ground paths; the HGLS1 streamlines assembly with a secure set-screw connection that eliminates thread-related delays. It complies with NEC/CEC standards and features UL certifications for Canada, plus a 150°C temperature rating for demanding environments. This grounding solution delivers reliable performance in ordinary/non-hazardous locations, while keeping weight down thanks to an aluminum lug and malleable iron body. For panel builders and system integrators, it offers straightforward installation, robust grounding, and proven long-term reliability in industrial control panels and switchgear housings.

FAQs
Yes. HGLS1 is specifically designed for 1/2 inch trade size rigid/IMC conduits and uses a set screw with an aluminum lug to establish a secure ground. Its threadless design reduces installation steps and simplifies field wiring in panels and enclosures, saving time without compromising grounding integrity.
Key specs include a 1/2 inch trade size, lug material aluminum, lug size #4-14 AWG, body material malleable iron, threadless connection, and a 150°C temperature rating. It is designed for rigid/IMC conduit and is suitable for ordinary/non-hazardous locations under NEC/CEC standards.
HGLS1 is specified for ordinary/non-hazardous locations. For installations in hazardous or classified areas, verify project requirements and consult applicable standards or manufacturer guidance to determine the appropriate grounding bushings and enclosure protection.
HGLS1 carries NEC/CEC standards compliance and UL Canada certification. These certifications support cross-border electrical installations and provide confidence in safety and performance for panel and enclosure grounding in commercial and industrial settings.
By eliminating threads, HGLS1 reduces installation time and labor costs while delivering a reliable ground path. The lighter aluminum lug and robust malleable iron body improve handling and durability, contributing to lower maintenance needs and a favorable total cost of ownership in automation projects.
