Grounding the switch with a grounding conductor buried in the
earth ground
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.
The angle iron must have a dimension no less than 50 × 50 × 5 mm (1.97 × 1.97 × 0.20 in) and the steel
tube must have a wall thickness no less than 3.5 mm (0.14 in) and be zinc-coated.
Weld the yellow-green grounding cable to the angel iron or steel tube and treat the joint for corrosion
protection.
