Overview

The NSI Industries 800T-2 2-Port Stacked Lug is a high-capacity set-screw connector engineered for heavy-duty electrical applications requiring compact conductor termination. Designed with stacked wire holes, this connector minimizes width while maximizing conductor capacity, making it ideal for space-constrained installations. Constructed from 6061T-6 aluminum alloy, the 800T-2 delivers superior mechanical strength and corrosion resistance, ensuring long-term reliability in industrial environments. Key specifications include a dual conductor range of 800-300 MCM, supporting both copper and aluminum conductors for versatile compatibility. The electro-tin plating ensures low contact resistance, critical for maintaining electrical efficiency and reducing heat buildup. With a UL486A/B listing and cULus certification (E155027), the 800T-2 meets stringent safety standards for 600V systems (2000V max per UL486B) and operates reliably at 90°C. The NEMA-standard 1.75" mounting hole spacing simplifies installation in panelboards, transformers, and switchgear. Applications span industrial power distribution, renewable energy systems, motor control centers, and commercial electrical infrastructure where high-current conductors demand secure, space-efficient termination. The set-screw design allows for tool-free reusability, reducing maintenance costs and downtime. Each unit includes a 3/8" hex wrench for precise torque application (550 in./lbs max), ensuring consistent performance across installations. With a compact footprint of 4.91" (L) x 3.00" (W) x 0.38" (H), the 800T-2 optimizes panel layout efficiency without compromising on current-carrying capacity. Backed by NSI Industries' reputation for durable electrical components, the 800T-2 is a trusted solution for engineers and contractors prioritizing performance, safety, and installation flexibility.
