Hubbell Premise Wiring HGBL250DB Copper Two-hole Lug

Product Description

The HUBBELL PREMISE WIRING HGBL250DB is a copper two-hole lug designed for terminating large-gauge conductors in electrical distribution and grounding applications. Rated for 250 kcmil wire, this lug accepts a 3/8 inch mounting stud and provides a secure, low-resistance mechanical and electrical connection. It is sold as a single unit and is suited for use in panelboards, switchgear, bus connections, and grounding assemblies. Licensed electricians and electrical contractors install this type of hardware during new construction, service upgrades, and industrial wiring projects where reliable conductor termination is required at large ampacity connections.

This two-hole lug is applicable in commercial and industrial electrical installations where 250 kcmil copper conductors require a bolted termination point. The dual-hole mounting pattern distributes mechanical stress and maintains positive contact at the connection surface. It is commonly found in main distribution panels, grounding electrode conductor terminations, and large feeder tap assemblies. The hardware category classification places it among standard electrical connection accessories used by licensed electricians across a wide range of fixed wiring systems.

Key Features

• Rated for 250 kcmil copper conductors for high-ampacity terminations
• Two-hole mounting design for secure, stable bolted connections
• Compatible with 3/8 inch mounting studs
• Copper construction for excellent conductivity and corrosion resistance
• Sold individually for precise quantity ordering

Compatibility

Designed as an OEM-style replacement or new-installation lug for use in electrical panelboards, switchgear, and grounding assemblies requiring 250 kcmil copper conductor termination with a two-hole bolted mounting configuration.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements for conductor terminations and grounding connections. De-energize and lock out the circuit or equipment before installing or replacing any lug hardware. Use calibrated torque tools as specified by the equipment manufacturer for bolted lug connections to ensure proper contact pressure. Inspect the conductor end and mating surface for cleanliness and damage before making the final connection.
