Hubbell Premise Wiring HGBL40DB1 Double Lug 4/0 Awg

Product Description

The HUBBELL PREMISE WIRING HGBL40DB1 is a double-barrel lug designed for terminating 4/0 AWG conductors in electrical distribution and grounding applications. It features a 3/8 inch outer diameter barrel and single-spacing configuration, making it suitable for panel boards, switchgear, and bus bar connections where large-gauge terminations are required. Licensed electricians and electrical contractors install this type of lug during service entrance work, main distribution panel builds, and industrial equipment wiring. The double-barrel design allows two conductors to share a single termination point, reducing the need for additional hardware in tight enclosures.

This lug is intended for use in electrical systems that require secure, low-resistance terminations on heavy-gauge copper or aluminum conductors. It fits typical applications such as main service panels, load centers, switchgear assemblies, and grounding electrode conductor connections. The 4/0 AWG rating places it in the heavy-duty range, commonly encountered in commercial electrical installations, industrial control panels, and large residential service entrances. The single-spacing configuration is suited for installations where lug placement must conform to standard bus bar spacing requirements.

Key Features

• Double-barrel design accepts two conductors at a single termination point
• Rated for 4/0 AWG conductor size for heavy-gauge applications
• 3/8 inch outer diameter barrel for precise fit in standard hardware configurations
• Single-spacing configuration compatible with standard bus bar layouts
• Sold individually, allowing exact quantity purchasing for project needs

Compatibility

Designed as an OEM-style replacement or new-installation lug for electrical panel boards, switchgear, and bus bar assemblies requiring 4/0 AWG double-barrel terminations with 3/8 inch outer diameter hardware.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the circuit or panel before installing or replacing lugs. Use the appropriate crimping or compression tool rated for 4/0 AWG lugs to ensure a secure, low-resistance connection. Do not over-torque mounting hardware without referencing the panel or equipment manufacturer torque specifications.
