How to make a perfect Earth
• Dig a pit of area 2 feet x 2 feet x 6 feet (L x B x D).
• Get a copper plate of size 1.5 feet x 1.5 feet x 0.25 feet.
• Connect a copper strip of size 1-inch wide, 3 mm thick and 6 feet length at the center of the copper plate
by welding or nuts and bolts.
• Insert a G.I. pipe onto the copper strip till it reaches the copper plate.
• Place this set up into the pit. Make sure that at least 4 inches of the G.I. pipe is above the ground level.
• Fill the bottom of the pit with a 1-inch layer of charcoal and salt in the proportion of 3:1 (3 parts charcoal, 1
part salt) and then cover with the soil.
• Connect a bare 14 SWG copper wire (double) on the top of the copper strip and run it to the exchange
room and connect it on the bus bar.
• The Bus bar is a copper strip, 4 inches long with 6 screws and nuts mounted on it. It has to be fixed on the
wall in the exchange room.
• The earth wire of the Primary Protection Modules (PPM)/system should be connected to this Bus bar.
• Water the earth at regular intervals.
