Overview

The NSi Industries 766-4 Service Entrance Cable Connector is a UL486A-listed, zinc die-cast component engineered for secure cable connections in industrial and commercial electrical systems. This connector features a .900 x 1.500-inch grommet opening, providing a tight seal against environmental elements such as moisture, dust, and corrosion. Certified for 600V maximum voltage and 90°C temperature rating, it meets NEC 310.15 requirements for ampacity based on conductor material and insulation type. Designed for compatibility with copper and aluminum conductors (8 AWG to 3/0 AWG), the 766-4 supports both aluminum-aluminum and aluminum-copper combinations. Its solid center barrier ensures proper conductor separation and electrical integrity. The zinc die-cast construction delivers superior corrosion resistance, making it suitable for indoor and outdoor installations, including service entrances, utility infrastructure, and telecommunications systems. Installation is simplified with standard compression tools and dies, reducing labor time while maintaining compliance with ANSI C119.4 and UL standards. Ideal for new installations or replacements, this connector guarantees reliable performance in demanding electrical environments where durability and precision are critical.
