Overview

NSI Industries CTH-4040 is a heavy-duty copper C tap compression connector engineered for reliable tap or parallel connections on 3/0 to 4/0 AWG stranded copper conductors. Built from high-conductivity copper alloy, the CTH-4040 delivers consistent electrical performance with low resistance and high pull-out strength, ensuring long-term joint integrity even in direct-burial applications. Its heavy-wall construction prevents joint relaxation after crimping, maintaining consistent compression over time. The C-shaped design simplifies installation, reducing labor time compared to traditional connectors while maintaining full UL486A (wire connector) and UL467 (grounding & bonding) compliance. Certified by CSA for electrical and grounding use, the CTH-4040 supports Class B or C building wire copper cable only and operates safely at up to 600V and 90°C. With a wire strip length of 13/16 inches and standard packaging of 3 units, this range-taking connector minimizes inventory needs by accommodating multiple conductor sizes in one SKU. Ideal for grounding electrode systems, parallel taps, and unbroken main conductor connections, the CTH-4040 is distributed by Gross Automation and meets NEC 250-81/250-91 grounding requirements. Compatible with Panduit and specified competitor crimping tools and dies, it ensures reliable performance in industrial, commercial, and utility applications where durability and compliance are critical.
