2. 2.3 UT10 Tower Grounding
1. Drive the ground rod close to the tower using a fence post driver or sledge
hammer. Drive the rod at an angle if an impenetrable hardpan layer exists.
In hard clay soils, a gallon milk 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. Insert one end
of the 4 AWG wire between the rod and the clamp and tighten the bolt
(Figure 2.
2-5).
3. Attach the tower grounding clamp to a tower leg (Figure 2. 2-5). Route the
4 AWG wire attached to the ground rod up the tower leg to the grounding
clamp. Loosen the set screw and insert the 4 AWG wire and the 24 AWG
enclosure ground wire into the hole behind the screw and tighten the
screw. Route the green wire to where the enclosure will be installed.
