Overview

The NSI Polaris IPLD750-4C Multi-Tap Dual-Sided Entry Vision Tap Connector is a pre-insulated, 4-port splicing solution engineered for secure, high-current connections in industrial and commercial electrical installations. Designed for conductors sized 750 to 250 MCM, this connector supports both copper and aluminum cables with a maximum operating temperature of 90°C and a voltage rating of 600V. Each dual-sided port is pre-loaded with oxide inhibitor to prevent corrosion and maintain low contact resistance over time. The ergonomic design features a smooth exterior finish for comfortable torque application with a hex key, while removable port plugs secure entry points and prevent debris ingress. Installation requires no additional supplies—simply strip the conductor insulation, insert into the port, and tighten the covered pressure screws to the specified torque. The IPLD750-4C is rated for parallel runs and is suitable for use in cable trays, panel boards, ducts, raceways, and troughs. Its heavy-duty 6061-T6 aluminum construction resists abrasion and chemicals, making it ideal for dry locations where durability and reliability are critical. Compatible with Class B and C conductors, this connector delivers a time-saving, all-in-one solution that eliminates the need for tape, covers, or additional sealing components. NSI Industries' Vision Tap line remains the industry standard for pre-insulated multi-tap connectors, offering unmatched versatility and ease of use in high-ampacity applications.
  • Clear Exterior: Vision Tap transparent design lets users see their work to ensure ideal conductor placement and the most secure connection
  • Dual-Sided Wire Entry: Form secure connections between 4 conductors quickly using the double-side entry ports sized for wires between 750 and 250 MCM
  • Ergonomic Design: Rounded corners and a smooth exterior finish over the abrasion-resistant plastisol insulation make Polaris connectors comfortable to grip
  • Pre-filled Oxide Inhibitor: All 4 dual-sided (DSE) entry ports are covered by removable plugs and pre-filled with an oxide inhibitor gel to protect against corrosion, debris or moisture
  • Professional Performance: The durable layer of insulation on each Polaris connector is UV, abrasion and chemical-resistant for reliable performance
