Overview

NSI Industries AL500-58 is a high-conductivity aluminum compression lug designed for 500MCM conductors, featuring a 5/8" bolt hole for secure mechanical connections. Manufactured from 6061T-6 aluminum alloy with electro-tin plating, this lug provides superior corrosion resistance and low contact resistance in harsh industrial environments. The center stop ensures proper cable installation depth, while die-indexed and color-coded markings simplify tool selection and installation consistency. UL486A/B and cULus listed to 35KV (when properly installed per cable manufacturer specifications), this lug meets NEC 310.15 ampacity requirements for 90°C operation. The 1-hole standard barrel design accommodates 500MCM aluminum conductors with a 5/8" stud hole (13.5mm diameter) and 1.74" hole spacing (44.5mm). Tin-plated construction inhibits oxidation, and the pre-filled oxide inhibitor with capped end plug ensures reliable long-term performance in outdoor or corrosive applications. Compatible with Panduit and competitor crimp die indices (P99), this lug is ideal for power distribution, substations, renewable energy systems, and industrial motor controls where high-current aluminum conductors require secure, code-compliant terminations. Temperature rated to 90°C with 600V maximum rating (2000V per UL486B for specific applications). Standard package quantity is 6 units.

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.
