Equipotential Bonding
Equipment Ground Bars
Proper bonding is essential to create an equipotential plane between service
grounds and equipment during fault and transient conditions. This
equipotential plane provides a near zero voltage differential and serves to
protect people and equipment during these events. The most popular
bonding product in use today is the ground bar or bonding bar. Ground bars
provide a convenient, single-point grounding and bonding location.
Conductors are welded to the bar using the CADWELD® process or are
mechanically fastened by using lugs.
ERICO® can design and manufacture custom bars. In addition, the breadth of
the product offering includes TMGB bars, which meet the requirements of
TIA/EIA 607 and conform to BICSI recommendations. Our perimeter bus
system allows for fast and easy field installation of halo and other perimeter
grounding schemes.
