Ground bars, also known as grounding busbars or earth bars, are metallic strips or blocks with multiple connection points used to terminate and bond multiple grounding conductors in electrical systems. They serve as a central hub to maintain a common electrical potential, providing a low-resistance path for fault currents to dissipate safely into the earth. Ground bars are typically installed in electrical panels, control enclosures, data centers, and telecommunications rooms.
