Leakage current
Leakage current is the current flowing via the operational insulation of a load to earth or a foreign conductive part. It can occur as a pure active current or as an active current with a capacitive component. VDE 0700-1 "Safety of household and similar electrical appliances" specifies the following leakage currents: for appliances of protection class 0 and 0I 0.5 mA; for portable appliances of protection class I 0.75 mA; for fixed motorised appliances of protection class I 3.5 mA; for fixed heating appliances of protection class I 0.75 mA or 0.75 mA/kW, max. 5 mA; for appliances of protection class II 0.25 mA; for appliances of protection class III 0.5 mA When considering leakage currents for an entire system (important e.g. also for RCDs), the leakage current (residual current) of the wires must be taken into account in addition to the leakage current of the consumables.
