2.4 Tripod Grounding
Ground the tripod and shown in Figures 2-1, 2-4, and 2-5.
1. Drive the ground rod close to the center of the tripod using a fence post
driver or sledge hammer. Slide the clamp down the rod before driving it
in the ground. This will eliminate the frustration of trying to get the clamp
to fit over a hammer damaged rod end. Drive the rod at an angle if an
impenetrable hardpan layer exists. In hard clay soils, a gallon jug of water
can be used to “prime” the soil and hole to make driving the rod easier.
2. Loosen the bolt that attaches the clamp to the ground rod. Strip 1 inch of
insulation from one end of the 4 AWG wire and insert it between the rod
and the clamp. Tighten the clamp bolt (Figure 2-4).
