When using the surface wire grounding system (SWGS), how far apart are the pegs typically placed?

The surface wire grounding system (SWGS) is designed to minimize the potential difference in electrical potential between various points in an installation while ensuring safety and stability in the grounding mesh. The placement of the grounding pegs is a critical aspect of this system to effectively facilitate grounding and to safeguard equipment and personnel against electrical hazards.

Typically, the pegs in an SWGS setup are placed about 4 feet apart. This distance is chosen to optimize the grounding effect, as it helps to create a conductive path that can dissipate electrical surges or faults into the earth. The spacing allows for the proper distribution of ground potential while minimizing the risk of step or touch potential hazards. Adequate spacing is essential for maintaining the effectiveness of the grounding system in various environmental conditions, making it a reliable choice for effective grounding practices.

Understanding the proper distance ensures that personnel can work safely around electrical systems, and it helps maintain operational integrity for equipment that relies on the grounding system to function correctly. This consistent spacing is a standard practice within military and civilian applications, ensuring uniformity and reliability in installations.
