Overview

The NSi Industries N-2SP All Purpose Split Bolt Connector is a dual-rated, electro-tin-plated copper split bolt designed for secure splicing of copper and aluminum conductors in industrial, commercial, and utility applications. This 2 AWG-rated connector accommodates wire combinations including aluminum-to-copper, aluminum-to-aluminum, steel-to-aluminum, copper-to-copper, and steel-to-copper, making it ideal for mixed-metal installations where corrosion resistance and electrical integrity are critical. The connector’s design ensures proper torque application via standard hex wrenches, with a recommended torque range of 27-50 inch-pounds for optimal performance. The N-2SP supports wire diameter ranges from 0.128" to 0.316" (2 AWG to 6 AWG), providing flexibility for various conductor sizes within a single SKU. Typical use cases include utility pole connections, grounding systems, motor controls, and industrial machinery wiring. The N-2SP’s dual-rated compatibility reduces inventory needs by eliminating the requirement for separate connectors for copper and aluminum applications.
