I have a couple of questions:
1) is there a limit to how many juction boxes you can have on one ring?
2) If you use a junction box to add additional sockets, can you then use a spur off the socket to continue your ring? so not to have a radial setup?
Consumer unit-----Socket----Junction box---Socket----socket---juction box----- back to Consumer unit.
Also how about...
Consumer Unit -----socket----junction box spur ----Socket -----socket-- back to consumber unit
in the second example I have made a ring out of the spur but the junction main circuit could carry on?
I hope I have made sense :)
