Overview

The NSI Industries CTH-2020 Heavy Duty Copper C Tap Grounding Connector is a range-taking compression connector engineered for reliable tap and parallel copper connections in grounding and bonding applications. Made from high-conductivity copper alloy, this connector meets NEC 250-81 and 250-91 requirements for connecting to grounding electrode systems. Its heavy-wall construction ensures consistent joint reliability by preventing relaxation after installation, while the innovative "C" shape design significantly reduces installation time compared to traditional connectors. Designed for copper conductors ranging from 1/0 to 2/0 AWG STR, the CTH-2020 accommodates both main and tap conductors within the same size range. This eliminates the need for multiple connector part numbers, streamlining inventory management and reducing stocking requirements. The connector is UL486A listed for wire connections and UL467 listed for grounding and bonding, with a temperature rating of 90°C and voltage rating of 600V. It is also CSA certified for electrical and grounding applications, making it suitable for direct burial installations. The CTH-2020 features positive all-around compression with low resistance and high pull-out values, ensuring a secure mechanical and electrical connection. Its heavy-duty construction provides long-term reliability in demanding industrial and commercial electrical systems. The connector requires a 11/16" wire strip length and is packaged in quantities of 3 per standard carton. For proper installation, use UL-listed crimping tools and dies as specified in the manufacturer's documentation. Ideal applications include grounding electrode systems, electrical panel connections, and parallel conductor installations in commercial buildings, industrial facilities, and utility infrastructure. The CTH-2020's compliance with multiple safety standards and its robust design make it a trusted choice for electrical contractors and engineers requiring dependable grounding solutions.
