Overview

The NSI Industries L20N-383 is a 2-hole long barrel copper compression lug engineered for high-current electrical terminations in industrial, commercial, and utility applications. Manufactured from high-conductivity copper tubing, this lug ensures optimal current transfer with minimal resistance, critical for high-performance electrical systems. The tin-plated finish provides superior corrosion resistance and maintains low contact resistance over time, extending service life in harsh environments. Designed for 2/0 AWG wire with an expanded range up to 4 AWG, the L20N-383 accommodates a 3/8" stud size and features a long barrel design for enhanced mechanical strength and ease of inspection. The 3/8" to 1 3/4" mounting bolt spacing offers versatile installation options, while the black color coding simplifies identification in complex wiring systems. The die-indexed marking system ensures proper tool selection and consistent crimping performance. Rated for 600V operation and suitable for applications up to 35KV when installed per manufacturer instructions, this lug meets UL486A and UL467 standards for wire connectors and grounding applications (sizes 8 AWG through 3/0 AWG). The 90°C temperature rating makes it ideal for demanding electrical environments, including motor control centers, switchgear, and renewable energy systems. For applications exceeding 2000V, consult cable manufacturer guidelines for voltage stress relief requirements. Compatible with standard compression tools, the L20N-383 is part of NSI Industries' L Series of long barrel copper lugs, known for reliability in critical power distribution applications. The product is distributed by Gross Automation and NSI Industries, with technical support available for proper tool/die selection.

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.
