Hi,
I've recently added five new sockets to a ring main and three ne lights to a lighting circuit. I have had a Periodic Inspection carrie out at the request of Building Control. The report states that there i a "Low Insulation Resistance reading". The inspector said that it coul be nothing (it could be a transformer somewhere on the circuit that i giving him misleading readings??), or that there may be a problem.
I am wondering what sort of things could cause a low insulatio resistance reading/ How serious is it? How likely could it be that thi is related to the new sockets/lights? When the electrician did th inspection, he told me that there was nothing that was a seriou problem but when I recieved the hard copy in the post, it raised thi issue. I appreciate that this is very little information to go on, bu I would just like to get a general understanding so I know a littl about it f I have to get an electrician to investigate. The rest of th installation is probably well over 20 years old
