WebJun 28, 2011 · “Typical earth resistances for single electrodes driven 1.2m deep are in the range of 50Ω to 100Ω (or more). If we apply the nominal 230V to such a resistance Ohm’s Law dictates that the current flow will be in the range of 2A to 5A. Even if the earth resistance is lowered to 10Ω the current will only be 23A.
