How to Install Copper Compression Connectors

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

Estimated time: 30m

Tools needed:

Wire strippers, Mechanical crimp tool, Multimeter

Supplies needed:

Copper compression connectors, Wire brush, Insulation tape

  1. Strip the conductor

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

  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 barrel of the connector, ensuring it is fully seated.

  4. Crimp the connector

    Use the appropriate mechanical crimp tool to crimp the connector securely onto the conductor, following the manufacturer's suggested crimp locations.

  5. Verify the connection

    Use a multimeter to check the continuity of the connection, ensuring there are no breaks or high resistance in the circuit.
