Overview

The NSI Industries L100NB is a single-hole, long barrel copper compression lug engineered for 1000 MCM flexible copper cables. This lug is constructed from high-conductivity copper tubing and features a tin plating for enhanced corrosion resistance and reduced contact resistance, ensuring reliable electrical connections in demanding industrial applications. Its design incorporates a gentle, continuous flared end, which significantly eases the insertion of flexible and extra-flexible cables, including those used in locomotive, welding, and mining equipment. This flared design also minimizes pressure on the cable strands post-installation, preventing chafing and breakage that can occur due to cable movement. The L100NB is rated for 600 volts and is exclusively for use with copper cables. It features a single mounting hole for straightforward installation. The lug is UL486A and UL467 listed for wire sizes 8 AWG through 3/0 AWG, meeting NEC 310.15 requirements and supporting a 90°C temperature rating. For expanded wire range capabilities, it is compatible with NSI's N12ID dieless compression tools. This compression lug is an ideal choice for grounding and bonding applications where robust and durable electrical connections are paramount. Part of NSI Industries' L Series, the L100NB provides a dependable solution for heavy-duty electrical systems.

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.
