Hubbell Premise Wiring HGBL04D90 Lug 4 Awg 90 Degree

Product Description

The HUBBELL PREMISE WIRING HGBL04D90 is a 90-degree lug designed for 4 AWG wire terminations. It features a double-barrel configuration with a 1/4 inch outer diameter and 5/8 inch hole spacing, making it suited for secure, space-conscious electrical connections. This type of lug is used to terminate stranded or solid copper conductors at panel boards, terminal blocks, and equipment enclosures. Licensed electricians and electrical contractors install these as part of branch circuit wiring, grounding assemblies, and equipment bonding work where a right-angle termination is required.

This lug is appropriate for commercial and residential electrical installations where 4 AWG conductors require a reliable mechanical and electrical connection at a 90-degree angle. The double-barrel design accommodates two conductors at the same termination point, which is common in panel wiring, junction enclosures, and bus bar connections. Its compact form factor supports installations in tight enclosures where straight lugs would create routing difficulties.

Key Features

• 90-degree angle orientation for right-angle conductor routing in tight enclosures
• Double-barrel design accepts two 4 AWG conductors at a single termination point
• 1/4 inch outer diameter mounting hole for standard fastener compatibility
• 5/8 inch hole spacing for consistent bolt-pattern alignment
• Sold individually for flexible quantity purchasing

Compatibility

Designed as an OEM-style replacement or addition lug for 4 AWG wire termination applications in residential and commercial electrical panels, terminal blocks, and equipment enclosures.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize and lock out the circuit before installing or replacing any lug. Use a calibrated torque tool when tightening fasteners to meet the terminal manufacturer's specifications listed on the equipment label. Verify conductor preparation, including proper strip length and absence of insulation damage, before seating conductors in the barrel.
