Overview

The NSI Industries GL214 is a high-conductivity copper compression lug engineered for secure, long-lasting electrical terminations in industrial and commercial applications. Manufactured from premium copper tubing with tin plating, this short barrel lug ensures corrosion resistance and minimal contact resistance for reliable performance. The GL214 supports 2 AWG copper cable with a 1/4" bolt size and features a peep hole for visual verification of complete conductor insertion, preventing improper terminations that could compromise system integrity. Designed for Class B or C building wire CU cable only, the GL214 is UL486A listed as a wire connector and UL467 listed for grounding and bonding applications (sizes 8 AWG to 3/0 AWG). It holds a cULus listing (155027) and is rated for 600V and 90°C maximum temperature. For applications exceeding 2000V, the lug is listed for up to 35KV when installed according to cable manufacturer voltage stress relief instructions. The lug is color-coded and marked with die index information for easy identification and selection, streamlining installation processes in high-volume environments. Ideal for use in motor control centers, panelboards, switchgear, and other electrical distribution systems, the GL214’s short barrel design accommodates tight spaces while maintaining robust mechanical and electrical connections. Its tin-plated copper construction resists oxidation and ensures low contact resistance, reducing heat buildup and extending service life. The peep hole feature provides a quick visual check to confirm proper cable seating, eliminating guesswork during installation and reducing the risk of future failures. Compatible with flexible and extra-flexible copper cables, including locomotive, welding, and mining cables, the GL214’s flared entry reduces pressure on cable strands, preventing chafing and breakage from movement. The lug’s compact design and high ampacity make it a dependable choice for applications requiring reliable grounding, bonding, or power distribution. Consult NEC 310.15 ampacity tables for specific conductor sizing based on insulation type and installation conditions.

Wire strippers, Crimping tool, Wire brush

Supplies needed:

Copper compression connectors, Cable

  1. Strip the conductor

    Carefully strip the insulation from the conductor without nicking the strands, ensuring the stripped length allows for complete insertion into the connector barrel.

  2. 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.

  3. Insert the conductor

    Insert the cleaned and stripped conductor completely into the connector barrel, ensuring it fills the barrel fully.

  4. Crimp the connector

    Using the appropriate crimping tool, apply pressure to crimp the connector securely onto the conductor, following the manufacturer's suggested crimp locations.

  5. Verify the connection
