Abb 54187 Copper Lug 500 Mcm Single Hole

Product Description

The ABB 54187 is a single-hole copper compression lug rated for 500 MCM conductors. It is designed for terminating large-gauge copper or aluminum conductors in electrical distribution systems, panelboards, switchgear, and service entrance equipment. The lug provides a secure, low-resistance mechanical connection at the termination point. Licensed electricians and electrical contractors install this type of lug during new construction, service upgrades, and panel replacement work. The single-hole barrel design accommodates 500 MCM wire, making it appropriate for high-ampacity feeder and service conductor applications.

This lug is used in commercial and industrial electrical installations where large conductors must be terminated reliably at busbars, lugs blocks, or equipment terminals. It is suited for service entrance, feeder circuits, and distribution equipment where 500 MCM conductors are specified. The brown color coding assists with conductor size identification during installation and inspection.

Key Features

• Copper construction for reliable conductivity and corrosion resistance at termination points
• Rated for 500 MCM conductor size for high-ampacity feeder and service applications
• Single-hole mounting for direct connection to busbars and equipment terminals
• Brown color coding for conductor size identification per industry convention
• Compression-style barrel for a secure, permanent mechanical and electrical bond

Compatibility

Designed as an OEM-style replacement compression lug for use in electrical distribution panels, switchgear, and service entrance equipment accepting 500 MCM single-hole copper lugs.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the circuit or equipment before installing or replacing any lug. Use the correct compression tool and die set specified for 500 MCM copper lugs to ensure a proper crimp. Verify torque requirements for the terminal or busbar connection point per the equipment manufacturer instructions before tightening the mounting hardware.
