30mA the five-fold test current is 0.25A.
- Because of safety reason, the measuring of the contact voltage will be executed,
with half the nominal fault current, before any other parameter will be tested.
- A selective RCD has an integrated leakage current function because of the
required delayed trip out. That is why the operator must wait for 30 s before reaching
final. The influence of the test current for contact voltage measurement will be
compensated now.
