Overview

The NSI Industries L2038 is a 1-hole long barrel copper compression lug engineered for secure, high-conductivity electrical terminations in medium-voltage and industrial power systems. Manufactured from high-conductivity copper tubing and tin-plated for corrosion resistance, this lug delivers low contact resistance and reliable performance in demanding applications. The long barrel design maximizes conductor surface area, ensuring stable connections under load and vibration. Rated for 2/0 AWG copper conductors with a 3/8" bolt size, the L2038 is optimized for medium-voltage installations up to 35KV when installed per cable manufacturer instructions. It features a die-index marking and color coding for easy identification and inventory management. The lug is UL486A listed as a wire connector and UL467 listed for grounding and bonding applications for wire sizes 8 AWG through 3/0 AWG. With a temperature rating of 90°C and a maximum voltage rating of 600V, the L2038 is suitable for power generation, transmission, and distribution systems, as well as industrial equipment and control panels. For applications exceeding 2000V, consult the cable manufacturer for voltage stress relief instructions. The L2038 is part of NSI Industries' L Series, designed for compatibility with standard compression tools and dies.

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, Multimeter

Supplies needed:

Copper compression connectors, Wire brush, Insulation tape

  1. Strip the wire insulation

    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 into the connector

    Insert the cleaned and stripped conductor completely into the barrel of the compression connector.

  4. Crimp the connector

    Use the appropriate crimping tool to securely crimp the connector onto the conductor, ensuring a strong mechanical and electrical connection.

  5. Verify the connection

    Use a multimeter to check the continuity and resistance of the connection to ensure it is secure and functioning properly.
