WEEB stands for "Washer, Electrical Equipment Bonding". The WEEB family of products are used to bond solar modules to solar mounts. The mounts are then grounded so the entire assembly is grounded. The WEEB Lug consists of a WEEB (Washer, Electrical Equipment Bond), lay-in lug, and hardware. It is used with one solid or stranded copper wire (6AWG to 14AWG), or two copper wires (10AWG to 12AWG) to provide a continuous ground on roof or ground mounted solar systems.
