I've just had my son in law on the phone about the wiring of an ex- council house they have just moved into.
He went to investigate some of the single wall sockets to see about putting doubles in and detected that a number had earth/neutral or line /neutral reversals. I'm not a professional but I am confident in my competency on domestic electrics, and am comfortable that he is competent enough (!) to inspect all the outlets (and lighting circuit, etc) and address the errors
My concern is the age of the wiring - I haven't seen the cables but his report is that it is PVC - red and black but the cpc is green insulated in the cable. I rewired my own house starting something like the late 70's and I don't remember cable like that. Just when was cable like that phased out for the uninsulated cpc, and will such age of cable be of concern? The fact that there are such blatant wiring errors already is of concern, and puzzlement how they exist - no, possibly not: explanation is quite possible that anyone could have changed the sockets at anytime for ones of a more up to date style.
Thanks
