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).
