Only really if you have measuring equipment capable of measuring very low resistances.Thanks John. Out of interest, other than distance/location from the fuse board, is there any other way of determining where in the ring a socket is?
However, unless there are some very devious and/or silly cable routes, the physical distance involved are likely to be a good guide. For example, to take an obvious and extreme example, in the case of an 'upstairs sockets circuit', with the CU/fuse board 'downstairs', none of the wiring upstairs will be 'near one end of the ring'.
Kind Regards, John
