It is recommended to use a residual current relay to
protect the user and the pump. Whichever type of
pump is to be used, it must be selected according to
the nominal current and voltage of that pump, and a
B type relay (which can open at DC current and high
frequency). (Grounding current should be below 3.5
mA according to EN 60335 standard.)).
