industrial earthing resistence should be very betwwen .5
ohms to 5 ohms.
0.5 ohms-excelent
0.5 to 1 ohms- very good
1 ohms to 1.5 ohms- good
1.5 to 2.0 ohms-satishfactory
2.0 ohms to 5 ohms- not satisfactory.
note imp- This resistence consider of near induviusal
earth pit only.equipement earthing value should be very
betwwen 0.5 ohms to 12 ohms depending on size & distence of
earthing netwerk(GI PATTI OR COPPER PATTI OR WIRE)utilise.
