Overview

The NSI Industries 500T is a single-port aluminum lug designed for secure, high-current electrical connections in industrial and commercial wiring systems. Constructed from 6061-T6 aluminum alloy, this lug delivers superior mechanical strength and corrosion resistance while maintaining low electrical resistance through electro-tin plating. The 500T accommodates conductor sizes from 500 MCM down to 4 AWG, supporting both copper and aluminum cables—eliminating the need for separate connector types and reducing inventory complexity. Engineered for reliability, the 500T features dual set screws per port to prevent loosening under vibration and thermal cycling, ensuring long-term connection integrity. With a voltage rating of 600V (2000V max per UL486B) and a temperature rating of 90°C, this lug meets the demands of high-power distribution systems, motor control centers, and panelboard applications. Its NEMA-standard mounting hole spacing simplifies installation in standard electrical enclosures, while the reusable design allows for cost-effective maintenance and system reconfiguration. Typical applications include branch circuit terminations, busbar connections, transformer leads, and industrial machinery wiring where high-current carrying capacity and environmental durability are critical. For larger conductor sizes, NSI offers complementary lugs in the 1000T series (1000–350 MCM) and panelboard-specific variants (1000LL2, 1000L2) with enhanced mounting features. Key specifications: Material—6061-T6 aluminum alloy; Surface finish—electro-tin plated; Conductor range—500 MCM to 4 AWG; Voltage rating—600V (2000V max); Temperature rating—90°C; Certification—UL 486A/B Listed; Mounting—NEMA standard hole spacing.
