Hubbell Premise Wiring HGBL01D1 Double Lug 1 Awg

Product Description

The HUBBELL PREMISE WIRING HGBL01D1 is a double-barrel grounding lug rated for 1 AWG conductors. It features a 0.25 inch outer diameter barrel and 0.625 inch hole spacing, making it a direct-fit hardware accessory for grounding and bonding applications. Licensed electricians install this lug when terminating ground conductors to bus bars, enclosure ground studs, or grounding blocks in panel and distribution equipment. The double-barrel design accepts two conductors at a single termination point, reducing hardware count on crowded ground bars.

This lug is suited for commercial and residential electrical installations where 1 AWG grounding conductors must be terminated to a fixed stud or threaded fastener. Typical applications include main service panels, sub-panels, switchgear enclosures, and equipment grounding connections. It is sold individually and is appropriate for use wherever a compact, code-compliant grounding termination is required for larger-gauge conductors.

Key Features

• Double-barrel design accepts two 1 AWG conductors at one termination point
• 0.25 inch outer diameter barrel sized for standard ground studs
• 0.625 inch hole spacing for direct mounting to bus bars and enclosure hardware
• Sold individually for single-point replacement or new installation use

Compatibility

Designed as an OEM-style grounding lug for use in residential and commercial electrical panels and enclosures requiring 1 AWG double-barrel terminations at 0.25 inch OD stud hardware.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize and lock out the panel or enclosure before making any terminations. Use a calibrated torque tool to seat the lug fastener to the enclosure or bus hardware per the equipment manufacturer's specifications. Do not exceed the conductor gauge rating of the lug.
