Which type of grounding radiates wires horizontally from a central point?

• A. Ground Loops
• B. Mesh Grounds
• C. Ring Grounds
• D. Star Grounds

Answer: (D)

In grounding schemes, how you route equipment grounding conductors affects current paths and noise control. A star grounding arrangement uses a single central point where all equipment grounding conductors connect, and from that point the conductors extend outward to each piece of equipment, like spokes radiating from a wheel. This setup gives each device its own direct, low-impedance path to earth and keeps the ground reference consistent, which minimizes voltage differences caused by current flow and reduces the potential for ground-loop currents. In contrast, configurations that form a loop or grid—such as rings or meshes—create multiple paths and larger loop areas, which can foster circulating currents and more noise between devices. Therefore, radiating wires outward from a central point best matches the idea of a star grounding.
