Typical Measurements
RCD Trip Test
During voltage tests in systems equipped with RCD circuit
breakers, a RCD switch can be tripped at a nominal
residual current of 10 mA or 30 mA by measuring the
voltage between L and PE.
The GT-55e and GT-85e are equipped with an internal load
enabling the tripping of an RCD protection device of 10 mA
or 30 mA.
Note: To prevent tripping an RCD, charge the unit first by
connecting the probes between L and N for approximately
5 seconds. Immediately afterwards, connect the probes
between L and PE.
