•
5 mA RMS for plug-connected equipment rated up to and including 32 A.
•
10 mA RMS for plug-connected equipment rated more than 32 A
•
10 mA RMS for equipment for permanent connection, without special measures for the
protective conductor.
•
5 % of the rated input current per phase, for equipment for permanent connection with a
reinforced protective conductor.
Conformity shall be checked using the measuring circuit shown below with a conventional
voltmeter and a welding equipment that is:
•
isolated from the ground plane
•
supplied by the rated supply voltage
•
not connected to the protective earth except through measurement components
•
the output circuit is in the no-load condition
•
interference suppression capacitors shall not be disconnected
NOTE!
The circuit given in the illustration below is used to obtain reproducible results.
