Set the RCD test parameters (I
dN
, current type, selectivity and contact voltage limit)
by clicking in the bottom left dark grey corner and selecting the appropriate RCD
settings.
In this case we use a 30mA RCD so in a 1-
phase TT earthing system which doesn’t
have water in the proximity. That is why the contact voltage limit may be set to 50
V.

If a schuko commander is to be used, plug the commander into the appropriate
outlet. If the cables are used, connect all cables appropriately
– the PE cable to
the PE conductor, the N cable to the N conductor and the phase cable to a phase
conductor (L1, L2 or L3).

key.
Expected results
In a normal situation, the contact voltage should be well below 1 V (please see chapter
RCD trip-out contact voltage test for more information), whereas the trip-out time and
