How plate type earthing install ?

Material required for earthing- Tools for digging, metallic plate, galvanised iron (GI) pipe, wire, coal, salt, water, water container

• Dig land in an area of 1.5 × 1.5m to a depth of approximately 3m
• To enhance the conductivity of soil, fill the pit with a mixture of coal and salt
• Place a 500×500×10mm copper plate in the pit. Attach this plate with a wire
• Pass the metallic wire attached to the copper plate, through a hollow part of GI pipe
• Fill the rest of the pit with a mixture of coal, sand and salt. Cover the top of the pipe with a T-section to prevent mud and dust from entering the pipe. In summer, the pit should be watered to keep it from drying.
