WebAug 31, 2024 · The 25-amp test requires that the impedance be less than 0.1 ohm at the end of the test period. The 30-amp test requires that the voltage drop across the grounding circuit be less than 4 volts at the end of the test period (less than 0.13 ohm). (A derivation of the grounding impedance limit value, 0.1 ohm, is presented in Technically Speaking ... WebJan 1, 2000 · A ground test showed 25 ohms to earth ground from the building steel, 180 ohms to earth ground from the transformer. Amazingly, there was an open circuit from the machine to the main ground! How can there be an open circuit with the machine's ground rod in place? That ground rod, for lack of bonding to the rest of the system, was irrelevant. ind aa rating
