WebAug 31, 2024 · Both tests measure the grounding circuit impedance at either 25 or 30 amperes. 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). WebWhenever carrying out the earth bond test on a long cable or an appliance with a long cable the above must be taken into account. The Pass mark for an appliance with a long cable would be 0.1ohms + cable resistance.
