Overview

NSI Industries GL4048B is a UL486A-listed, 600V-rated copper compression lug designed for secure, corrosion-resistant connections with flexible copper cables. This single-hole, short-barrel lug accommodates 4/0 AWG to 1 AWG flexible copper cables, including locomotive, welding, and mining cables, with an expanded wire range when used with the NSI N12ID dieless compression tool. The connector features a gently flared entry to simplify cable insertion into the 0.547" ID barrel, reducing strand damage and chafing during installation and operation. Tin-plated for enhanced corrosion resistance and low contact resistance, the GL4048B is ideal for high-current applications where reliability is critical. The 1/2" bolt size and 0.512" mounting hole diameter ensure compatibility with standard hardware, while the 1.000" length and 0.689" outer diameter provide a compact yet robust termination solution. Temperature-rated to 90°C and cULus listed (File No. 155027), this lug meets NEC requirements for grounding and bonding (sizes 8 AWG to 3/0 AWG) and is suitable for applications up to 35kV when installed per manufacturer instructions. The GL4048B is color-coded purple for easy identification and includes a peep hole for visual verification of cable insertion. NSI Industries, a trusted name in industrial connectors, delivers durable, high-conductivity copper tubing for consistent performance in demanding environments.

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.
