Checking the thermal stability in terms of earthing conductor
cross-section and surface contact with the ground installation earthing
rho]r is the resistivity of the earthing conductor ([micro][ohm].
The earthing grid resistance mainly depends on the area taken up by the earthing grid, the total length of buried earthing conductors and the number of earthing rods/electrodes.
Therefore all metal parts must be bonded to an adequate earth wire which connects all appliances, water and gas pipes to the main earthing conductor
at the consumer unit.
