Question

what is diameter of g.i pipe required for the earth wires to be taken out?​

Answer 1

Answer:

The earth wire should be taken through G.I pipe of 1mm diameter for at least 32cm length above and below ground surface to the earth electrode to safeguard against mechanical wear and tear.

Answer 2

The diameter that is used for the G.I pipe which is required for the earth wires to be taken out is 13mm.

Why G.I pipe is used in earth wires?

• For doing factory wiring, neutral wiring, house wiring, etc the galvanized iron pipe is used as a pile of earth electrodes.
• The diameter of the G.I pipe which is used for the earth wire is 13mm.
• The G.I earth wires are used when there is high soil resistivity. When this wire is used the ground becomes the low-impedance ground.
• It protects it from dangerous electric fault and also from heavy lightning energy.
