Overview

The NSI Industries N-3SP All Purpose Split Bolt Connector (SKU: N-3SP) is a high-strength, solderless electrical connector designed for reliable wire splicing in industrial and commercial applications. This versatile connector accommodates a 3 AWG conductor size with a main and tap wire diameter range of 0.128 to 0.258 inches, making it ideal for joining aluminum-to-copper, aluminum-to-aluminum, steel-to-aluminum, copper-to-copper, and steel-to-copper configurations. Engineered with an electro-tinned copper body, the N-3SP ensures superior conductivity and corrosion resistance, even in harsh environments. The connector is UL486A/B listed for wire connections and UL486D listed for direct burial applications, providing flexibility for underground installations. Supplied with a nut, spacer, and pressure pad, the N-3SP delivers optimal wire pull-out strength and a secure, long-lasting electrical connection. Key specifications include a recommended torque of 275 inch-pounds and a standard carton quantity of 50 units. Its dual-rated capability for aluminum-to-copper connections and compatibility with multiple conductor types make it a cost-effective solution for a wide range of electrical systems, including power distribution, industrial machinery, and renewable energy installations.
