9.4.1 Measuring the protective conductor current

(with devices of protection class I)

The limit value is 3.5 mA.

The protective conductor 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. The protective conductor current can either be
measured directly with the substitute leakage current method or with the differential
current method.

In the case of test objects in PC I with touchable conductive parts
that are not connected to the protective conductor, an additional
touch current measurement must be carried out according to PC II
(see Diagram 1 on Page 20).
