Overview

The NSI Industries ASC400T is a dual-rated aluminum compression splice engineered for 400 MCM conductors, delivering reliable electrical connections in industrial and utility applications. Manufactured from high-conductivity aluminum tubing, this splice ensures optimal current transfer with minimal resistance. The center stop design guarantees precise cable alignment during installation, preventing over-insertion and ensuring consistent performance. Electro-tin plating provides superior corrosion resistance, extending service life in harsh environments where moisture, chemicals, or salt exposure are concerns. Each splice is color-coded and marked with die index information for quick identification and correct tool selection. Pre-filled with oxide inhibitor and capped with a matching color-coded cap, the ASC400T prevents oxidation at the connection point, maintaining signal integrity over time. The splice is UL486A/B listed for wire connectors and rated for 600V maximum operation, with a 2000V maximum rating per UL486B. Temperature rating is 90°C, compatible with AL9CU conductors. For installation, use NSI’s N1240 or N121D crimp tools. The expanded wire range spans 400 MCM to 4/0 AWG when paired with the NSI N12ID dieless compression tool. Physical dimensions include an outer diameter of 1.190 inches, inner diameter of 0.760 inches, and a length of 4.878 inches. Standard carton quantity is 6 units. Ideal for power distribution, renewable energy systems, and industrial motor controls where aluminum-to-aluminum splicing is required.

How to Install and Crimp an ASC400T Aluminum Compression Connector

Install the correct ASC400T aluminum compression connector on a compatible conductor, prepare the wire properly, and crimp it to the manufacturer’s specifications. Follow the strip-length and crimp-location guidance to ensure a secure, code-compliant connection.

Tools needed:

Wire stripper, Wire brush, Approved crimp tool (NSI N12ID dieless crimp tool or compatible UL-approved tool, die set as required by the connector series)

Supplies needed:

ASC-T series aluminum compression connector, Compatible conductor sized to the connector chart, Oxide-free cleaned conductor end

  1. Select the correct connector size

    Choose the proper ASC-T lug or splice connector for the conductor size you are installing. Verify that the wire range, color code, and strip length match the chart before starting. Do not use a connector that does not match the cable size.

  2. Strip the conductor to the specified length

    Carefully strip the insulation from the conductor without nicking or damaging the strands. Strip only enough so the conductor can be completely inserted into the connector barrel and fill it fully. Use the strip length listed for the selected wire size.

  3. Clean the stripped conductor

    Wire brush the stripped portion of the conductor to remove any oxide film. Make sure the exposed conductor is clean before insertion, since contamination can reduce connection quality and conductivity.

  4. Insert the conductor fully into the barrel

    Insert the cleaned conductor completely into the connector barrel until it is fully seated. Confirm that the stripped portion is completely inside the barrel and that no bare conductor is left exposed beyond the connector.

  5. Crimp the connector at the marked locations

    Use the approved crimp tool and apply the number of crimps specified for the connector series and wire size. Follow the barrel markings for suggested crimp locations when using NSI N12ID and N1240 tools. For splice connectors, apply the required number of crimps per side.

  6. Verify the finished connection

    Inspect the completed crimp to confirm the connector is secure, properly aligned, and fully compressed. Ensure the conductor cannot be pulled out and that the installation matches the manufacturer’s crimp and tool requirements.
