Have come accross a job where house ring run in T/E but has an old extension with earthed metal conduit used for sockets and only live and neutral single cores (of which are both black here).
The earth continuity is greater than 500 ohms and the live is faulty between 2 sockets and disconnected.
For now I have down rated mcb to 16A and looking at rewiring the sockets with the conduit wiring.
My issue is that it is a solid floor covered with laminate, a flat roof and internal walls are stone with current metal conduit and boxes fitted during build within the stone work.
Would it be acceptable to rewire the sockets using SWA on the outside of the building to replace this part of the ring (5 sockets in total to rewire on a final circuit of 18)
Any other ideas/advice appreciated as cannot seem to find any other way.
