Overview

The ABB LCN75 is a Type LCN copper two-hole lug engineered for high-reliability electrical terminations in medium-voltage applications up to 35kV. Designed by ABB - Installation Products, this lug features a long barrel for superior conductor strain relief and a 1/2-inch bolt hole for secure mounting. The lug accommodates wire sizes up to 750 kcmil, making it ideal for heavy-duty power distribution systems where robust conductor termination is critical. Constructed from high-conductivity wrought copper and finished with electro tin plating, the LCN75 ensures long-term corrosion resistance and optimal electrical conductivity in industrial environments. The black die color code simplifies tooling selection and installation accuracy, aligning with ABB's Color-Keyed® System for compression connectors. This lug is part of ABB's Blackburn® line of compression connectors, which are trusted in applications ranging from utility substations to industrial motor control centers. The two-hole design provides enhanced mechanical stability compared to single-hole alternatives, reducing the risk of loosening under vibration or thermal cycling. For installations requiring visual verification of conductor insertion, the LCN75 is available with optional peep holes (suffix -PH), allowing technicians to confirm proper seating before compression. The lug's 600V to 35kV voltage rating covers a broad spectrum of medium-voltage systems, including those in power generation, renewable energy, and heavy manufacturing. With a focus on electrical integrity and mechanical durability, the LCN75 delivers dependable performance in mission-critical infrastructure where failure is not an option.

How to Install Copper Compression Connectors (LCN CU)

This guide provides step-by-step instructions for the safe and proper installation of copper compression connectors, including lugs and splices, ensuring a secure and reliable electrical connection.

Estimated time: 15m

Tools needed:

Wire strippers, Wire brush, Crimping tool, Appropriate crimping die set

Supplies needed:

Copper compression connector (lug or splice), Copper cable, Clean cloth

  1. Prioritize Safety and Disconnect Power

    WARNING: Risk of shock, disconnect all power to the circuit before beginning installation. CAUTION: This product must be installed by a qualified electrician in accordance with all national and local electrical codes.

  2. Confirm Connector and Cable Compatibility

    Verify that the copper compression connector (lug or splice) is compatible with the specific AWG size and type of copper cable being used. Refer to product specifications and the 'Tool and Die Index' if unsure.

  3. Strip Cable Insulation

    Carefully strip the insulation from the end of the cable to the appropriate length, ensuring that the cable's strands are not damaged during the stripping process.

  4. Wire Brush the Cable

    Using a wire brush, thoroughly clean the stripped portion of the cable that will be inserted into the connector. This removes oxidation and ensures a good electrical connection.

  5. Fully Insert Cable into Connector

    Insert the prepared, stripped, and brushed cable fully into the barrel of the compression connector until it bottoms out. Ensure no stray strands are outside the connector.

  6. Crimp the Connector

    Consult the 'Tool and Die Index' provided in the documentation to select the appropriate crimping tool and die combination for your cable size. Crimp the connector the number of times specified in the chart, ensuring crimps are uniformly spaced along the barrel or splice.

  7. Clean Excess Oxide Inhibitor

    After crimping, wipe off any excess oxide inhibitor that may have been expelled from the connector during the crimping process using a clean cloth.
