14.5 Checks
Earth conductor check
D0000071793
Check the earth conductor (in Germany DGUV3, for example)

Insulation resistance
To check the effectiveness of the insulating properties of the ap-
pliance, we recommend conducting a differential current test of
the earth conductor current/leakage current.
