Grounding to a buried grounding conductor
If the installation site has no grounding strips, but earth ground is available, hammer a 0.5 m (1.64 ft) or
longer angle iron or steel tube into the earth ground to serve as a grounding conductor, as shown in
Figure 22.
The dimensions of the angle iron must be at least 50 × 50 × 5 mm (1.97 × 1.97 × 0.20 in). The steel
tube must be zinc-coated and its wall thickness must be at least 3.5 mm (0.14 in).
Weld the yellow-green grounding cable to the angel iron or steel tube, and treat the joint for corrosion
protection.
