Single Point Grounding is the concept of bonding all equipment to a common point, commonly PBB.

Explanation:
Single Point Grounding means tying all equipment grounds to one common node, typically the Point Bonding Bus (PBB). This creates a single reference potential for the entire system, which minimizes ground loops and stray currents that can cause noise, interference, or damage to equipment. In practice, you bond chassis, cabinets, shields, and signal grounds to the PBB, and connect the PBB to the site’s grounding electrode system. The result is a stable, low-impedance grounding network that improves safety, surge protection performance, and RF integrity.
