A repair eng came to repair my washing machine, but prior to working he tested my supply and found an earth fault resistance >200ohms (rcd protected circuit). then refused to carry out repairs until rectified.
my situation is as follows.
Power fed from overhead lines
Earth rod outside(sandy soil), continuity check carried out from sockets to rod ok
sockets tested with rapidtest plug all wired ok.
unable to trip RCD when short applied across earth/neutral.
neutral has floating voltage of about 2-4V
Is this the norm or do I need new RCD, earth rod/rods?
please advise.
