ICT Primary Bonding Busbar (PBB) provides a central bond attachment point for ICT bonding backbones, equipment and the building’s ground electrode system. Hole patterns on Busbars accommodate two-hole lugs per the recommendation of ANSI/BICSI N3-20 and ANSI/TIA-607 standards. Insulators electrically isolate Busbars from the wall or other mounting surfaces, thereby controlling the current path.
