How to Install Aluminum Compression Lugs and Splices

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

Estimated time: 30m

Tools needed:

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

Supplies needed:

Aluminum compression lug or splice (Type ATL/ASP), Aluminum or copper conductor, Oxide inhibitor

  1. Turn Off Power

    WARNING: ELECTRICAL HAZARD! Before beginning any work, ensure all power to the circuit is completely turned off to prevent electrical shock or injury.

  2. Verify Connector and Wire Size

    Check the wire size marked on the aluminum connector to confirm it is the correct connector for the actual cable size you intend to use.

  3. Strip Cable Insulation

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

  4. Brush Conductor

    Thoroughly brush the conductor side that will be inserted into the connector using a wire brush (e.g., T&B catalog number WWB1) to remove any oxidation.

  5. Insert Conductor

    Fully insert the prepared conductor into the aluminum connector until it reaches the internal stop or bottoms out completely.

  6. Crimp Connector

    Refer to the 'Tool and Die Index' to select the correct tool and die combination for your specific cable size. Crimp the connector the number of times indicated in the chart. 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 subsequent crimps uniformly along the barrel.

  7. Clean Excess Inhibitor

    Wipe off any excess oxide inhibitor that may have been displaced during the crimping process to ensure a clean finish.
