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

The correct distance between the pegs in a surface wire grounding system (SWGS) is 4 feet. This spacing is designed to ensure effective grounding for both safety and functionality, creating a low-resistance path for electrical faults and helping to prevent damage from lightning strikes or other electrical surges. Maintaining this distance also helps in reducing the potential for interference with the surrounding environment and equipment, which is particularly important in military applications where reliability and safety are critical.

Choosing 4 feet as the optimal spacing incorporates both practical engineering standards and field-tested results for ensuring adequate grounding performance in various operational conditions.
