Overview

The NSI Industries Polaris IT-750C Multi-Tap Dual-Side Entry Connector is a pre-insulated, 2-port splicing solution engineered for secure, high-current connections between 750 and 250 MCM copper or aluminum conductors. Designed for installation in cable trays, panel boards, ducts, raceways, or troughs, this connector eliminates the need for traditional uninsulated options by integrating insulation, oxide inhibitor, and access plugs into a single, tool-ready assembly. The clear polycarbonate body allows visual confirmation of conductor placement and proper seating before final torqueing with a hex key and torque wrench. Each port is pre-loaded with oxide inhibitor to prevent corrosion, and removable access plugs enable unused entry points to be sealed, reducing installation time and material waste. The IT-750C is dual-rated for 75°C operation with aluminum (AL7CU) and copper (AL9CU) conductors, supporting maximum ampacities of 475A for copper and 385A for aluminum. Its ergonomic, abrasion-resistant design resists chemicals and physical damage, while the integrated plastisol insulation provides dielectric protection up to 600V. Installation requires no additional tape, covers, or specialized tools—just strip the conductors, insert them into the designated ports, and secure the hex screws to the manufacturer’s torque specifications. Available in multiple port configurations to match application requirements, this connector is the standard choice for professionals prioritizing speed, safety, and long-term performance in high-current distribution systems.
