Overview

The NSI Industries 800T-4 is a 4-port stacked lug connector engineered for high-current industrial applications where space efficiency and reliability are critical. Constructed from 6061-T6511 aluminum alloy and tin-plated for superior conductivity and corrosion resistance, this connector delivers low-resistance connections for both copper and aluminum conductors. Each of the four ports accepts conductor sizes ranging from 800 AWG to 300 MCM, making it ideal for heavy-duty power distribution in motor controls, substations, renewable energy systems, and utility installations. The stacked port configuration minimizes the overall width of the connector to 2.63 inches, enabling denser panel layouts and reducing space requirements in tight enclosures. Rated for 600 volts (with a maximum of 2000V per UL486B), the 800T-4 operates efficiently at temperatures up to 90°C. The mounting hole spacing follows NEMA standards at 1.75 inches, ensuring compatibility with standard electrical enclosures and equipment. Key specifications include a maximum tightening torque of 500 in/lbs, a hex size of 1/2 inch, and dimensions of 4.91 inches in length, 3.00 inches in height, and 2.63 inches in width. With its robust construction and versatile wire range, the 800T-4 is a dependable solution for high-current applications requiring compact, high-performance connectivity.
