OK all heres the scenario fitting new cu in a house its on old 3036 type no rcds in sight . anyway testing reveles no ring curcuit one 2.5 supplys all sockets the other 2.5 in the same fuse holder supplys one socket upstairs in corner bedroom ? took socket off has 2 live & 2 neutral black/red wires ? propity has been extended at back and side . not been in this trade long but is it common practice to put a ring upstairs and spur downstairs ? because all groundfloor sockets look like spurs. :smile5:
