8.4. Measuring the substitute leakage current for devices of
protection class I
The substitute leakage current procedure is an alternative method
for measuring the protective conductor current.
The limit value is 3.5 mA.
The substitute leakage current for test objects with heating
elements having a total connected power greater than 3.5
kW must not be greater than 1 mA/kW heating power, up to
a maximum value of 10 mA.
