Overview

NSi Industries N-2SP All Purpose Split Bolt Connector is a versatile, UL 486A/B listed wire connector designed for secure splicing of copper and aluminum conductors in industrial, commercial, and utility applications. This 2 AWG-rated split bolt accommodates 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. Key specifications include an electro-tin-plated body for enhanced corrosion protection, a UL listing for copper and copperweld wires only, and a supplied assembly including nut, spacer, and pressure pad. 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. NSi Industries, a trusted manufacturer in the electrical connector market, delivers this product with a focus on durability and reliability. The electro-tin plating inhibits oxidation, maintaining low contact resistance over time, while the pressure pad ensures consistent mechanical and electrical connections even in demanding environments. This split bolt is particularly suited for applications requiring direct burial grounding, as it meets UL 486D standards for direct bury installations. 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. With a temperature rating of 90°C and voltage rating up to 600V (2000V per UL 486B), this connector meets the demands of modern electrical systems. NSi Industries’ reputation for quality and compliance with UL standards ensures that the N-2SP split bolt connector delivers long-term performance in critical electrical connections.
