FAQs

HGLS3 is designed for rigid/IMC conduit with a 1 inch trade size and a threadless connection, plus a set-screw lug. For best results, align the lug with the conduit bore, tighten the set screw to spec, and ensure full seating to maintain a low-impedance grounding path. Use compatible conductor sizes (#4-14 AWG) to optimize contact area and thermal performance.
Yes. The lug is aluminum and supports #4-14 AWG conductors, making it well-suited for typical control wiring in industrial panels. The malleable iron body provides structural integrity while the aluminum lug delivers good conductivity, enabling reliable, maintenance-friendly grounding in compact installations.
HGLS3 is designed to NEC/CEC-compliant standards and is classified for Ordinary/Non-Hazardous locations. Supporting documentation includes UL Canadian certification references, validating its suitability for multi-region electrical installations while ensuring safety and regulatory compliance.
Key specs include a 1" trade size, conduit typeRigid/IMC, lug material Aluminum, and a temperature rating of 150°C. The body is malleable iron, and the connection is threadless with a set screw. Overall weight is 0.13 lb, with dimensions around 1.63 in by 1.63 in and a height of 0.75 in, making it compact for panel use.
By combining a threadless, easy-install design with a reliable aluminum lug and a broad conductor range, HGLS3 reduces installation time and maintenance costs. Its 150°C rating supports high-temperature environments, reducing the likelihood of grounding failures and downtime in automated systems, which translates to lower total cost of ownership.
