Course ground is how deep when putting a ground in?

• A. Three feet
• B. Five feet
• C. Six feet
• D. Four feet

Answer: (C)

Grounding depth is about getting the electrode into soil that stays moist enough to conduct well and staying below surface disruptions like frost. Driving the ground rod to six feet typically places it into deeper, more stable soil where moisture is present and the electrical path remains reliable even in adverse surface conditions. Shallower depths, like three or four feet, can sit in drier or frost-affected layers, causing higher resistance and a weaker ground. Five feet may still miss those conditions in some soils, but six feet is routinely taught as the depth that offers a dependable, low-resistance path to earth.
