Grounding the device by using a grounding conductor buried
in the earth
If earth is available at the installation site, hammer a 0.5 m (1.64 ft) or longer angle iron or steel tube
into the earth to serve as a grounding conductor. Weld the yellow-green grounding cable to the angel
iron or steel tube and treat the joint for corrosion protection.
