Overview

The NSI Industries GL40048 is a 1-hole short barrel copper compression lug engineered for high-reliability electrical terminations in industrial and commercial applications. Manufactured from high-conductivity copper tubing and tin-plated for corrosion resistance, this lug ensures low contact resistance and long-term performance. The integrated peep hole allows visual confirmation of complete cable insertion, eliminating installation errors and ensuring secure connections. Designed for Class B or C building wire (CU cable only), the GL40048 supports a wire range of 400 MCM and accommodates a 1/2" bolt size. Key specifications include a barrel ID of 0.547", barrel OD of 0.689", length (L) of 2.362", width (W) of 0.472", and mounting hole diameter (E) of 0.512". The lug features a temperature rating of 90°C and is UL486A listed for 600V applications. For installations exceeding 2000V, it is rated for 35KV maximum when installed per cable manufacturer voltage stress relief instructions. The connector is marked with die index information and color-coded for easy identification and inventory management. Its flared end design simplifies cable insertion for flexible and extra-flexible cables, reducing strand damage and chafing. Ideal for demanding electrical infrastructure, including power distribution, motor control centers, and industrial machinery.

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.
