Overview

The NSI Industries AL500N-NT is a double-hole narrow aluminum compression lug designed for high-current electrical connections up to 500 MCM. Constructed from 6061T-6 aluminum alloy with a tin-plated finish, it ensures low contact resistance and corrosion resistance in harsh environments. This UL 486A/B and cULus listed connector is rated for 600V (2000V max per UL486B) and 90°C temperature operation, making it suitable for industrial and utility applications. Key features include a double-hole mounting design with 1/2" stud holes and NEMA-standard 1.75" hole spacing for secure, turn-prevent connections. The color-coded barrel markings (Pink) and Panduit die index (P99) simplify crimp die selection for proper installation. Compatible with both copper and aluminum conductors, the AL500N-NT is optimized for use with NSI N1240 or N121D crimping tools. Its enclosed barrel design inhibits corrosion and ensures reliable current transfer in demanding electrical infrastructure projects.

How to Install Aluminum Compression Connectors

This guide provides step-by-step instructions for installing aluminum compression connectors, ensuring a secure and reliable electrical connection.

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.
