WebAny leakage current flowing in the green safety ground wire would be seen as a non-zero reading at position #2, and any leakage current from the load to earth would show a non-zero reading at positions #2 or #3. Since the green wire is included in the test at position #3, only the ground current is registered as leakage in that case. WebLeakage current measuring devices use this impedance circuit for measurements. Additional important points regarding IEC 60601.1 include: The use of up to 25 amperes ac for protective earth testing (this is a type-test and generally suitable for manufacturers) Leakage current is measured at 100 percent of mains voltage
