1. Place the ground rod clamp on the ground rod. Secure it about 8 cm (3 in) from the top.
Do this before the rod is driven into the ground. Be careful not to damage the clamp with
the hammer.
2. Taking care not to damage power or communications lines, drive the 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.
3. Strip 3 cm (1 in) of insulation from both ends of the 4 AWG ground cable.
4. Strip 3 cm (1 in) of insulation from the lower end of the 10AWG ground wire.
5. Loosen the set screw on the lug and insert the 4 AWG and 10 AWG wire.
6. Tighten the set screw (
(p. 19)).
7. Loosen the ground rod clamp. Insert the 4 AWG wire. Tighten the clamp (
19)).
