disconect the sockets!! possibly a faulty one !!!

or a trapped wire by screw

70 Mohms...!....not exactly REALLY low, Have you plastered any boxes in or installed on damp walls?,if so condensation in the backbox might be the cause.Otherwise I wouldnt worry about it,as long as all your other readings measure up it's well over the minimum acceptable reading.

its LOW considering its a new Supply!!

Has it just been plastered?

its LOW considering its a new Supply!!

Difficult and probably a waste of time to track down a reading that high IMO....if there was a real problem such as pinched wire etc the reading would be a lot lower.

Hi i have labc to site on monday

When i take all the sockets and fcu's off i was getting >200 ohms and i test all the sockets all ok but when connected getting all kind of readings as low as 30 megger ohms
if i leave the tester lock on will claim to 160

it's got to be damp p-laster

Wouldnt worry too much about it its that time of the year now nothing seems to dry out very quickly bet you would get a much higher reading in july only needs a little pressure on the back boxes when screwed back to get a lower reading also make sure everything is disconnected even diodes on fused spurs
