How to Install the L75048 Copper Compression Connectors

This guide provides step-by-step instructions for installing L75048 copper compression connectors, ensuring a secure and reliable electrical connection.

Estimated time: 30m

Tools needed:

Wire strippers, Crimping tool, Wire brush

Supplies needed:

Copper compression connectors, Cable

  1. Strip the cable insulation

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

  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 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. Ensure that the crimp is tight and secure.

  5. Verify the connection

    Inspect the crimped connection to ensure it is secure and that there are no visible gaps or loose strands.
