WebThe material used for the earth electrode must be the same as an earth wire. The least sectional region of earth lead wired should not be low as compared to 0.02 sq. inch & not above 0.1 square .inch. According to a normal rule, the earth conductor size must be low as compared to the line conductor’s half of the section. WebThe key difference between earthing and grounding is that the term “ Earthing ” means that the circuit is physically connected to the ground, which is Zero Volt Potential to the Ground (Earth). Whereas in “ Grounding ”, the circuit is not physically connected to the ground, but its potential is zero with respect to other points.
