Overview

NSI Industries C-2/0 Long Barrel Tinned Copper Splice (SKU: C-2/0) is a high-conductivity copper compression connector engineered for reliable electrical connections in demanding industrial applications. Manufactured from premium copper tubing with a tin-plated finish, this splice delivers superior corrosion resistance and long-term performance in harsh environments. Key specifications include UL486A and UL467 (Grounding & Bonding) listings, a temperature rating of 90°C, and a maximum voltage rating of 600V. The connector supports wire ranges from 2/0 AWG to 4 AWG, with an expanded range of 2/0 AWG to 4 AWG when used with NSI’s N12ID dieless compression tool. The long barrel design ensures robust crimp integrity, while serrations indicate proper crimp locations for consistent installation. Color-coded and die-indexed for easy identification, the C-2/0 splice features a 2.25-inch length, 0.441-inch inner diameter (I.D.), and 0.563-inch outer diameter (O.D.). It is suitable for use at voltages up to 35KV when installed according to cable manufacturer voltage stress relief instructions, with a maximum of 5KV for bare splices. The connector is ideal for Class B or C building wire copper cables and meets NEC 310.15 ampacity requirements. Applications include power distribution, grounding systems, industrial machinery, and renewable energy installations where reliable, high-amperage splices are critical. The tin-plated copper construction resists oxidation and ensures low contact resistance, reducing heat buildup and extending service life. With a standard carton quantity of 25, the C-2/0 splice is a cost-effective solution for high-volume installations. NSI Industries, a trusted name in electrical connectors, backs this product with rigorous quality control and compliance to industry standards. For tooling compatibility, refer to NSI’s compression tool specifications on page 87 of their catalog.

How to Install Copper Compression Connectors

This guide provides step-by-step instructions for installing copper compression connectors, ensuring secure and reliable electrical connections.

Estimated time: 30m

Tools needed:

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

    Inspect the crimped connection to ensure it is secure and that there are no visible gaps or loose strands.
