Overview

The NSI Industries N-1000SP All Purpose Split Bolt Connector is a heavy-duty, electro-tinned copper alloy connector designed for reliable electrical connections across multiple conductor types. This 1000 MCM split bolt connector accommodates aluminum-to-copper, aluminum-to-aluminum, steel-to-aluminum, copper-to-copper, and steel-to-copper applications, making it one of the most versatile connectors in the NSI N-Series lineup. Key specifications include a UL486A/B listing for copper and copperweld wires, with a recommended torque range of 900-1100 inch-pounds for optimal performance. The electro-tinned body provides superior corrosion resistance and low contact resistance, ensuring long-term reliability in both indoor and direct burial applications. Each N-1000SP includes a hex nut, spacer, and pressure pad for secure, vibration-resistant connections. This connector is engineered for high-current applications where conductor compatibility is critical. The split bolt design allows for easy installation and reconfiguration, while the pressure pad ensures consistent force distribution across the conductor interface. With a wire diameter range accommodating 250 MCM to 1000 MCM conductors, the N-1000SP reduces inventory requirements by eliminating the need for multiple connector sizes. Ideal for utility, industrial, and commercial electrical systems, the N-1000SP meets the demands of high-voltage installations up to 600V and 90°C temperature ratings. The UL486D listing for direct burial applications further expands its utility in underground and exposed environments. NSI Industries, a trusted manufacturer of electrical connectors, backs this product with industry-standard certifications and a commitment to quality.
