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.
