At what angle should you drive the static wand grounding rod?

• A. 0 degrees
• B. 90 degrees
• C. 30 degrees
• D. 45 degrees

Answer: (D)

Grounding for static discharge relies on creating a solid, low-impedance path to earth so charges can dissipate safely. Driving the grounding rod at forty-five degrees into the ground gives a good balance of depth and stability in typical field soils, providing solid contact with moist soil while resisting being knocked out of place. Driving it horizontally doesn’t reach enough depth for a reliable path, and driving it straight up and down can be less stable in soft ground. A shallower angle like thirty degrees offers less depth and stability than forty-five, so the forty-five-degree angle is the practical choice for reliable grounding.
