Overview

The ABB AL 500 N 24 HS Aluminum Two-Hole NEMA Lugs are precision-engineered for high-current electrical connections in industrial and utility applications. Designed to accommodate 477-500 kcmil and 500-600 Compact AL-CU (Aluminum-Copper) and ACSR (Aluminum Conductor Steel Reinforced) cables, these lugs ensure reliable, low-resistance terminations for power distribution systems. Specifically, they are suitable for ACSR cable types 397.5 (26/7) and 477 (18/1). The 24-inch length provides ample clearance for installation, while the pad, measuring 1-3/4 inch wide by 3-9/16 inch long and 29/64 inch thick, offers robust mechanical support. The barrel measures 19-5/8 inches long with a 1-5/16 inch outside diameter, fitting securely over conductor ends. Two 9/16 inch diameter holes, spaced on 1-3/4 inch centers, allow for secure mounting with standard hardware. The pink cap signifies the presence of an oxide inhibitor, which prevents corrosion and ensures long-term conductivity. The included heat shrink provides additional environmental protection for the termination. These lugs are compatible with installing dies 106A, 300, 317, 1 5/16, 14A, and 15A, meeting NEMA standards for electrical terminations.
