Additional descriptions
Note
Usable in all low-voltage systems between L-N or L-PEN.
Only usable in IT Systems between L-PE and N-PE, if the exposed-
conductive-parts (bodies) of the equipment of the low-voltage installation
is connected to the earthing arrangement of the transformer substation.
(interconnected earthing arrangement of the HV-transformer substation
with the bodies of the LV-installation. RE = RA accordance to IEC
