Overview

The NSI Industries Polaris IT-4B Multi-Tap Single-Side Entry Connector is a pre-insulated, 2-port splicing solution engineered for secure, high-quality connections between 4 AWG and 14 AWG conductors. Designed for installation in cable trays, panel boards, ducts, raceways, or troughs, this connector eliminates the need for tape, coverings, or additional supplies during assembly. The aluminum alloy body is wrapped in high-dielectric strength plastisol insulation, providing resistance to abrasion, chemicals, and UV rays while maintaining a comfortable ergonomic grip. Each port is pre-loaded with an oxide inhibitor to prevent corrosion and ensure low contact resistance, and removable access plugs cover unused ports to prevent debris ingress. The IT-4B is dual-rated for copper and aluminum cables, with maximum ampacity ratings of 95A for copper and 75A for aluminum at 90°C operating temperature. Rated for 600V and suitable for Class B and C conductors, this connector is cold-temperature rated to -45°C (-49°F) and meets UL 486A-486B standards for dry locations. Installation requires only a hex key and torque wrench, with torque specifications provided in the manufacturer's documentation. The single-side entry design simplifies conductor insertion and secures connections with covered pressure screws, making it ideal for parallel configurations and UL-listed applications. Part of NSI Industries' Vision Tap series, the IT-4B combines durability, versatility, and ease of use for electrical splicing in industrial, commercial, and utility environments.
