In the process of renewing a light fitting in our kitchen today, I discovered that our lighting cables have only two wires - live and neutral - no earth! This is probably the original wiring from the mid 1960's.
The cables are individually coated in plastic within a grey plastic sleeve but are multistrand and not the single strand copper wire of today.
I had a hell of a job trying to fit these multistrand wires into the fitting and gave up in the end. I solved the problem by using a plastic terminal block and running modern cable from this to the light fitting but the earth terminal in the fitting is not connected to anything.
It works but I am wondering how this fits in with modern wiring regulations especially since part P has come into force. Would there be any problems if we decided to sell the house or rent it out?
