Overview

The NSI Industries GL400N is a 2-hole short barrel copper compression lug engineered for high-voltage electrical terminations. Designed for 400 MCM copper conductors (4/0 AWG to 400 MCM range), this lug features a 1/2" bolt size and is rated for a maximum of 35kV when properly installed. Constructed from high-conductivity copper tubing and tin-plated for corrosion resistance, the GL400N ensures low contact resistance and long-term reliability in demanding applications. Key specifications include a barrel length of 1.181 inches, an outer diameter of 0.949 inches, and a width of 1.386 inches. The lug has a tang length of 2.992 inches and a thickness of 0.177 inches, with mounting hole spacing of 1.750 inches and a hole diameter of 0.512 inches. The end of the connector to center measurement is 0.618 inches, and the overall length is 4.685 inches. The GL400N is color-coded blue for easy identification and tool selection. A critical feature is the integrated peep hole, which allows visual verification of complete cable insertion, ensuring a secure and reliable termination. The lug is UL486A listed and cULus listed (155027), meeting industry safety standards. It is designed for Class B or C building wire copper cable only, with a temperature rating of 90°C and a voltage rating of 600V. For applications exceeding 2000V, follow the cable manufacturer's voltage stress relief instructions. This compression lug is ideal for high-voltage electrical systems, including power distribution, industrial machinery, and utility installations where secure, corrosion-resistant terminations are critical. The GL400N is a reliable choice for professionals requiring durable, high-conductivity connectors for 400 MCM conductors.

How to Install Copper Compression Connectors

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

Estimated time: 30m

Tools needed:

Wire strippers, Mechanical crimp tool, Multimeter

Supplies needed:

Copper compression connectors, Wire brush

  1. Strip the conductor

    Carefully strip the insulation from the conductor to a length that allows the stripped conductor to fill the barrel of the connector completely.

  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 is fully seated.

  4. Crimp the connector

    Use the appropriate mechanical crimp tool to crimp the connector securely onto the conductor, following the manufacturer's suggested crimp locations.

  5. Verify the connection

    Use a multimeter to check the continuity of the connection, ensuring that it is secure and functioning properly.
