Hi, first post so hope someone can help.
We've just moved house and I am looking at adding a number of additional sockets. My first 'project' is the study where I need to add probably at least 8 sockets (ie 4 doubles). I was going to do this by extending the ring ideally using existing single socket.
However, last night I got the floorboards up to discover a couple of junction boxes already exist. So, I know I'm asking you to guess but can anyone give me an informed opinion as to what has already been done if I describe some of the connections?
Cable from next room goes into JB1 and exits to JB2. From JB1, a cable goes to the single socket. This socket has a 2nd cable exiting to somewhere else (ie under the landing where I haven't got the boards up yet). From JB2, there are 3 cables (in addition to the one coming/going to JB1). One cable goes again towards the landing. One cable I have traced to the outside wall coming from downstairs (connection to downstairs ring?).Third cable looks like it may also go downstairs or poss to other room (can't yet get to other end).
If you managed to draw that, any ideas?

The main CU only has one fuse for the Ring Main (ie there is no Upstairs Ring and separate Downstairs Ring).
