Overview

The NSI Industries AL400N is a 400 MCM, 2-hole aluminum compression lug engineered for medium-voltage electrical terminations up to 35 kV. Constructed from high-conductivity 6061T-6 aluminum alloy with electro-tin plating, this lug delivers low contact resistance and superior corrosion resistance in harsh environments. The 2-hole standard barrel design accepts 1/2" bolts for secure mechanical fastening, while the center stop ensures proper cable installation depth for consistent crimping results. Key specifications include a barrel length of 2.299 inches, an outer diameter of 1.190 inches, and a wire range of 400 MCM to 4/0 AWG. The lug features a green color code for die index identification and is pre-filled with oxide inhibitor to prevent oxidation. UL486A/B and cULus listed to 35 kV when installed per cable manufacturer specifications, the AL400N meets stringent safety and performance standards. For applications exceeding 2000V, consult cable manufacturer voltage stress relief instructions. The color-coded die index markings simplify tool selection and crimp verification, reducing installation errors. Trusted in power distribution, substations, and renewable energy installations, the AL400N ensures long-term reliability where performance and safety cannot be compromised.

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.
