Hi,
I have just moved into my new flat, and have started my wiring install.
I have come across some old, very old BT wiring which comes into the flat and is still in use. It is paper insulated, i.e. the paper is just twisted around the conductors, it would seem in two layers.
The second layer is marked with a "II" on two of the wires and a "I" on two, I assume for two lines? I can not see which of the two is supposed to be the "A" or "B" wire, in each pair.
Has anyone come across this before? Any ideas / tips?
