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, Insulated wire

  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 connector barrel, ensuring it is fully seated.

  4. Crimp the connector

    Use the appropriate crimping tool 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.
