Which grounding method radiates wires horizontally from a central point?

The grounding method that radiates wires horizontally from a central point is known as the star ground. In this configuration, multiple grounding conductors extend outward from a single central grounding point, resembling the shape of a star. This design helps ensure that all equipment and systems grounded to this central point are referenced to a common ground potential, minimizing ground loops and electrical interference.

The star ground method is particularly effective in reducing potential differences between various grounding locations, making it advantageous for minimizing noise in sensitive electronic systems. This arrangement allows for a lower impedance path to ground, improving the overall performance of electrical systems.

In contrast, methods such as ground grids or ground loops serve different purposes and do not exhibit the same radiating layout from a central point. Ground grids, for example, focus more on creating a large surface area that provides a low-resistance path to ground rather than a centralized structure. Therefore, the unique characteristics of the star ground method make it the correct answer in this context.
