Nsi Industries L35048 Copper Compression Long Lug 350 Mcm

Product Description

The NSI INDUSTRIES L35048 is a tin-plated copper compression long lug designed to terminate 350 MCM conductors with a one-hole, 1/2-inch mounting configuration. The closed barrel design creates a sealed, moisture-resistant connection when crimped, forming a mechanically strong, vibration-resistant bond between the connector and conductor. Red color-coding and a legible die index allow for fast identification during installation. This lug is installed by electricians using a standard compression crimp tool and is suited for high-ampacity termination work in commercial and industrial electrical systems.

This lug is used in secondary power distribution applications across a range of settings, including commercial buildings, power plants, and industrial facilities. It is well-suited for terminating large-gauge conductors at busbars, switchgear, panelboards, and electrical equipment where a reliable, long-barrel compression connection is required. The chamfered port aids conductor entry and ensures consistent seating before the crimp is applied.

Key Features

• Tin-plated copper construction for improved conductivity and corrosion resistance
• Closed barrel design seals against moisture and contamination
• Chamfered conductor port for easier insertion of 350 MCM wire
• Red color-coding and die index markings for quick identification
• One-hole mount with 1/2-inch bolt hole for straightforward panel termination
• Crimp-installed for a homogenous, vibration-resistant mechanical bond

Compatibility

Designed as an OEM-style compression lug for 350 MCM copper conductors requiring a one-hole, 1/2-inch mounting termination in secondary power distribution applications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements for large-conductor terminations. De-energize and lock out the circuit before installing or removing any compression lug. Use a properly sized compression crimp tool with the die index marked on the lug to ensure a correct, full crimp. Do not re-crimp a lug that has already been fully compressed onto a conductor.
