How to Install the 60278N Aluminum Lugs

This guide provides step-by-step instructions for installing and wiring the 60278N aluminum lugs for optimal electrical connections.

Estimated time: 45m

Tools needed:

Screwdriver, Wire strippers, Multimeter

Supplies needed:

Mounting screws, Terminal connectors, Joint compound, Belleville compression washers

  1. Prepare the cable

    Strip the insulation from the cable to a length of 3-3/8 inches as specified for the 60278N. Be careful not to nick the cable strands.

  2. Apply joint compound

    Smear a thin layer of joint compound onto the stripped end of the cable. Use a wire brush or emery cloth to clean the cable before inserting it into the connector.

  3. Insert and compress the connector

    Insert the cable into the connector until it stops, ensuring the insertion length matches the stripped cable length. Use the appropriate die and compress the connector on the colored bands, starting near the tongue. Ensure to perform four compressions as required.

  4. Secure the connection

    Bolt the lug to a pad using a Belleville compression washer to maintain tension. Ensure the connection is secure and free from sharp edges or burrs.

  5. Verify the installation

    Use a multimeter to check the continuity and resistance of the connection. Ensure that the connection meets electrical standards.
