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, Multimeter

Supplies needed:

Copper compression connectors, Wire brush

  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 fills the barrel fully.

  4. Crimp the connector

    Using the appropriate crimping tool, crimp the connector securely according to the manufacturer's specifications. Verify the crimp with a multimeter for continuity.
