Hubbell Premise Wiring HGBL30DB Grounding Lug 3/0 Awg

Product Description

The HUBBELL PREMISE WIRING HGBL30DB is a double-barrel grounding lug rated for 3/0 AWG conductors. It is designed to provide a reliable mechanical and electrical connection point in grounding assemblies within electrical distribution systems. The lug features a 3/8 inch stud opening and a single-hole mounting configuration. Electricians and electrical contractors install this hardware accessory during service panel work, grounding electrode system installations, and equipment bonding applications where large-gauge conductors require a secure termination point.

The HGBL30DB is suited for residential and light commercial electrical installations where 3/0 AWG grounding conductors are terminated to bus bars, grounding bars, enclosures, or structural steel. The double-barrel design allows two conductors to be terminated at a single lug point, which is common in panelboard grounding bus extensions and supplemental grounding electrode connections. This lug is sold as a single unit and is appropriate for use by licensed electricians performing grounding and bonding work.

Key Features

• Double-barrel design accepts two 3/0 AWG conductors at a single termination point
• 3/8 inch stud hole for mounting to grounding bars, bus bars, or enclosure knockouts
• Single-hole mounting configuration for straightforward panel or enclosure installation
• Sold individually, allowing procurement of exact quantities needed per job
• Designed for use in grounding and bonding applications per NEC requirements

Compatibility

Designed as an OEM-style grounding lug for use with 3/0 AWG conductors in standard electrical grounding and bonding assemblies requiring a 3/8 inch stud opening.

Installation Notes

Installation should be performed by a licensed electrician. De-energize and lock out the panel or equipment before installing or servicing any grounding lug. Conductor preparation and torque requirements should follow the lug manufacturer instructions and NEC Article 250 guidelines for grounding and bonding. Do not exceed the rated conductor size for this lug.
