FAQs
The HGLS10 is designed for rigid/IMC conduit as a grounding path. Its threadless, set-screw design simplifies alignment and secure fastening, reducing installation time and the risk of damage to conduit threads. This makes it a reliable choice for panel boards, enclosures, and equipment spaces where rigid or IMC conduit is standard.
The lug capacity of the HGLS10 supports #3/0-6 AWG conductors, providing a wide range of compatibility for feeder and grounding conductors. The aluminum lug combined with a malleable iron body offers a robust, lightweight connection suitable for typical non-hazardous industrial installations.
Yes. The HGLS10 carries a 150°C temperature rating, allowing use in elevated temperature spaces without additional accessories or derating. This rating, along with its rigid/IMC compatibility, makes it suitable for motor control centers, switchgear, and other hot ambient installations.
The HGLS10 complies with NEC/CEC standards and is UL-listed with Canadian certifications for grounding equipment. It is designed for ordinary/non-hazardous locations, supporting regulatory compliance in typical commercial and industrial facilities without special enclosure or location modifications.
The threadless design eliminates the need to chase and tap threads, reducing installation time and potential cross-threading issues. Combined with a set-screw fastening, it provides repeatable, secure connections even in tight spaces, simplifies retrofits, and minimizes maintenance in ongoing operations.
