Overview

The NSI Industries ASC3/0T Dual Rated Aluminum Splice is a high-conductivity compression connector engineered for professional electrical installations requiring reliable, corrosion-resistant splices. Manufactured from premium 6061T-6 aluminum alloy, this splice ensures optimal electrical conductivity while resisting oxidation and corrosion through electro-tin plating. The ASC3/0T accommodates 3/0 AWG conductors with an expanded range of 3/0-2 AWG, making it ideal for both primary and secondary splicing applications in industrial, commercial, and utility environments. Key features include a center stop for precise cable alignment, pre-filled oxide inhibitor to prevent corrosion at the connection point, and a color-coded cap for easy identification and compliance with installation standards. The splice is UL486A/B listed for wire connectors and rated for 600V maximum (2000V per UL486B) with a temperature rating of 90°C, ensuring safe operation in high-load scenarios. When installed with NSI’s N1240 or N121D crimp tools, the ASC3/0T delivers consistent, low-resistance connections suitable for applications up to 35kV when installed per cable manufacturer specifications. Designed for durability and ease of use, the ASC3/0T is color-coded (Ruby) and marked with die index information for tool compatibility. Its compact dimensions (0.760" O.D., 0.480" I.D., 2.878" length) and standard carton quantity of 12 make it a practical choice for bulk installations. Whether splicing aluminum or copper conductors, this splice provides a secure, long-lasting connection trusted by electricians and engineers in demanding electrical systems.

Estimated time: 30m

Tools needed:

Wire strippers, Crimping tool, Wire brush

Supplies needed:

Aluminum compression connectors, Cable

  1. Select the appropriate connector

    Choose the correct lug or splice connector based on the size of the cable being installed, ensuring it matches the specifications in the provided chart.

  2. Strip the cable insulation

    Carefully strip the insulation from the conductor without nicking the strands, leaving enough length to fully insert the stripped conductor into the connector barrel.

  3. 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.

  4. Insert the conductor into the connector

    Insert the cleaned and stripped conductor completely into the connector barrel, ensuring it fills the barrel completely.

  5. Crimp the connector

    Using the appropriate crimping tool, crimp the connector according to the manufacturer's specifications, ensuring the number of crimps is per side for a splice connector.

  6. Verify the connection

    Inspect the crimped connection to ensure it is secure and that there are no visible gaps or loose strands.
