Answer / pradeep kumar dhar
The resistance value varies according to the nature of the
soil.It is very high for rocky soils.A value of 1 ohm or
less is considered to be very good.Several pits are
interconnected to reduce the value of earth resistance.

Answer / parmod kumar
The resistance value of Earth Pit should below 1 Ohm &
Earth pit are connected to reduce the earth resistance
value.

Answer / ajoy kumar
In some cases like rocky soil, the resistance value of individual earthpit become more than 5 ohms. For these cases, we can consider the combined earthing and it should be atleast less than 1 ohm.
