(1) copper ground lug, bolt
(1) ground rod, clamp
5.3.3.2 Pole Grounding Procedure
Use the following procedure to ground the pole (FIGURE

ground rod close to the foundation using a fence post driver or sledge
hammer. Drive the rod at an angle if an impenetrable hardpan layer exists.
Soften hard clay soils with water if necessary.
