Overview

The ABB 2B20BB is a Type 2B two-bolt copper connector engineered for secure electrical splices and taps in power distribution systems. This connector is designed to join copper conductors with a main wire range of 2 AWG to 2/0 AWG stranded and a tap conductor range of 8 AWG solid to 2/0 AWG stranded. The 1/2" bolt size ensures robust clamping force for stable, long-term connections. Constructed from high-strength copper alloy castings and bolts, the 2B20BB delivers excellent conductivity and corrosion resistance, critical for reliable performance in industrial and commercial electrical systems. The removable cap simplifies installation, while neoprene washers integrated into the bottom casting capture bolts for ease of use. This connector is UL 486A listed for copper conductors only, meeting industry standards for safety and performance. Dimensions are optimized for compact installations, with a length of 1 15/16 inches, height of 1 3/4 inches, and diameter of 5/16 inches. The absence of a spacer in this model streamlines assembly for specific conductor configurations. Ideal for applications requiring direct, dependable splices or taps, the ABB 2B20BB is a practical choice for electricians and engineers working with copper conductors in power distribution networks.
