The GL750NB is specifically engineered for 750 MCM copper conductors and features a 1/2" bolt size with a 1.750" mounting hole spacing (D dimension). This lug is UL486A Listed as a wire connector and is rated for 600V maximum, with a 90°C temperature rating. For applications exceeding 2000V, it is listed for 35KV maximum when properly installed according to the cable manufacturer's voltage stress relief instructions. The GL750NB is part of the GL-NB series, designed for flexible copper cables, including Diesel Locomotive (Class H and M) and Welding cable types, with specific compatibility for 750 MCM, 600 MCM, and 500 MCM cable sizes. Key dimensions include an I.D. of 1.040", O.D. of 1.310", a length (L) of 5.512", and a width (W) of 1.900". Each lug is clearly marked with the die index and color-coded for easy identification and selection, simplifying inventory management and installation processes. The short barrel design and gentle, continuous flare at the connector end facilitate easy insertion of flexible and extra-flexible cables, while also reducing strand pressure and protecting against chafing and breakage from cable movement. This lug is supplied with a standard carton quantity of 3.

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.
