Overview

The NSI Industries GL350NB is a 2-hole short barrel copper compression lug specifically designed for flexible and extra-flexible copper cables. This lug is rated for cable sizes up to 350 MCM. Its construction features a gentle, continuous flared end, which is engineered to ensure ease of cable insertion, particularly for flexible and extra-flexible cable types. These include applications such as locomotive wiring, welding cable, and mining cable, among others. The flared end serves a dual purpose: it simplifies the insertion process and, after installation, it reduces the pressure exerted on the cable strands. This reduction in pressure helps to protect the cable strands from chafing and breakage that can occur as a result of cable movement. The GL350NB is constructed from copper and is tin-plated. This tin plating provides enhanced corrosion resistance, ensuring the longevity and reliability of the connection in various environments. The lug is rated for 600 volts and is exclusively for use with copper cables. It features a single mounting hole for secure attachment. The bolt size for this compression lug is 1/2". The SKU for this product is GL350NB, and its UNSPSC code is 39121449.

How to Install Copper Compression Connectors

This guide provides step-by-step instructions for installing copper compression connectors, ensuring secure and reliable electrical connections.

Estimated time: 30m

Tools needed:

Wire strippers, Crimping tool, Wire brush

Supplies needed:

Copper compression connectors, Cable

  1. Strip the conductor

    Carefully strip the insulation from the conductor without nicking the strands, ensuring the stripped length allows for complete insertion into the connector barrel.

  2. Clean the conductor

    Use a wire brush to clean the stripped portion of the conductor, removing any oxide films to ensure a good electrical connection.

  3. Insert the conductor

    Insert the cleaned and stripped conductor completely into the connector barrel, ensuring it fills the barrel fully.

  4. Crimp the connector

    Using the appropriate crimping tool, apply pressure to crimp the connector securely onto the conductor, following the manufacturer's suggested crimp locations.

  5. Verify the connection

    Inspect the crimped connection to ensure it is secure and that there are no visible gaps or loose strands.
