How to Install ATL and ASP Aluminum Compression Lugs and Splices

This guide provides step-by-step instructions for safely installing Thomas & Betts Type ATL and ASP aluminum compression lugs and splices on stranded, compressed, compact aluminum, and copper conductors.

Estimated time: 15m

Tools needed:

Wire strippers, Wire brush (T&B catalog WWB1), Crimping tool, Appropriate crimping dies

Supplies needed:

Aluminum compression lugs or splices (Type ATL/ASP), Aluminum or copper conductors, Oxide inhibitor

  1. Turn Off Power

    Turn off all electrical power to prevent electrical hazard before beginning installation. Failure to do so may result in serious injury or death.

  2. Verify Connector and Wire Size

    Check the wire size marked on the aluminum connector to ensure it matches the actual cable size to be used for the connection.

  3. Strip Cable Insulation

    Carefully strip the cable insulation from the conductor, taking care to avoid damaging the conductor's strands during this process.

  4. Brush Conductor

    Wire brush the conductor side that will be inserted into the connector. Use a wire brush, such as T&B catalog number WWB1, to ensure a clean and optimal connection.

  5. Insert Conductor

    Fully insert the prepared and brushed conductor into the aluminum compression connector until it reaches the stop.

  6. Crimp Connector

    Refer to the provided Tool and Die Index to select the correct tool and die combination for your specific cable size. Crimp the connector the specified number of times. For splices, make the first crimp just outside the knurl on each side of the center and space subsequent crimps uniformly along the splice. For lugs, make the first crimp at the inner end of the barrel and space crimps uniformly along the barrel.

  7. Clean Excess Inhibitor

    After crimping, wipe off any excess oxide inhibitor from the completed connection to ensure a clean finish.
