Use as a common negative/neutral bus for AC or DC systems. Dual terminal strips in 4 or 8 screw positions on 3/4" centers are secured to a high density insulating base. All hardware, bus material and fasteners are nickel-plated brass. #8 screws accommodate various size ring terminals and each terminal strip is rated for 100 amps. Interlocking bases allow use of multiple terminal strips and bus bars to produce secure and neat wiring assemblies. The terminal strip bases have provisions for either #8 or #10 mounting screws, and no conductive parts in the base are exposed to the mounting surface.
