Overview

The NSI Industries Polaris IT-250C Multi-Tap Dual-Side Entry Connector is a pre-insulated, 2-port splicing solution engineered for secure, high-current connections between two conductors in industrial and commercial wiring systems. Designed for wire sizes ranging from 250 MCM to 6 AWG, this connector supports both copper and aluminum cables with current ratings of 290 A (copper) and 230 A (aluminum) at 600 V. The clear plastisol body provides full visibility of conductor placement during installation, while the ergonomic design resists abrasion and chemical exposure, ensuring long-term reliability in harsh environments. The dual-side entry ports allow conductors to be inserted from either side, with removable access plugs included to seal unused ports—eliminating the need for additional tape or covers. The connector is rated for 90°C operation and cold temperatures down to -45°C, making it suitable for outdoor and indoor applications in cable trays, panel boards, ducts, raceways, and troughs. Key benefits include: - Pre-loaded oxide inhibitor for corrosion resistance and long-term conductivity. - No additional supplies required—just strip, clean, insert, and torque to spec. - Compatible with standard hex keys and torque wrenches for precise installation. - Dual-rated for copper/aluminum, reducing inventory needs for mixed-material systems. The IT-250C is part of the Polaris IT Series, a trusted line of pre-insulated connectors known for durability and ease of use in splicing applications. For parallel configurations or other port configurations, NSI Industries offers a full range of Polaris connectors to match project requirements.
