Moroso 90724 Aluminum Mechanical Lug 500 Mcm

Product Description

The MOROSO 90724 is an aluminum mechanical lug rated for 500 MCM conductor size. Mechanical lugs use a set-screw or bolt-clamping method to secure conductors without soldering, making termination faster and more reliable in the field. This lug is suited for use in electrical panels, switchgear, bus connections, and distribution equipment where a solid, code-compliant termination is required. Licensed electricians and electrical contractors are the primary installers. The aluminum construction keeps weight low while maintaining conductivity appropriate for large-gauge feeder and service-entrance applications.

The 90724 is intended for 500 MCM aluminum or copper-clad aluminum conductors in commercial and residential electrical distribution systems. Typical applications include service-entrance terminations, main panel lugs, and feeder connections in load centers and switchboards. This lug is well suited for installations where large-conductor terminations must meet NEC requirements for mechanical fastening and conductor retention.

Key Features

• Rated for 500 MCM conductor size for heavy-duty feeder and service-entrance use
• Aluminum construction reduces weight compared to copper alternatives
• Mechanical clamping design eliminates the need for soldering during termination
• Suitable for use in panels, switchgear, and distribution equipment

Compatibility

Designed as an OEM-style mechanical lug for use with 500 MCM conductors in electrical panels, load centers, and switchgear requiring large-gauge mechanical terminations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the panel or equipment before beginning any termination work. Use the appropriate torque wrench to tighten lug fasteners to the manufacturer-specified value printed on the lug body or supplied documentation. Verify conductor preparation, including proper stripping length and freedom from nicks, before seating the conductor in the lug barrel.
