I want to put a socket upstairs in what is to become my computer room. I
have an old (pre-socket) junction box on the skirting downstairs, which is
fed from the master socket, and which in turn feeds 2 single socket boxes.
The junction box has four wires coming in from master socket.- orange
connected to terminal I shall call 'A', blue connected to 'B' green and
brown not connected. then the 2 socket boxes are connected opposite way
round to each other, ie one is connected A to No 2 and B to No 5, the other
is connected A to No 5 and B to No 2. Does it not make any difference which
way round they are, are phones/modems/PCs not polarity sensitive?
Can I just connect 2 and 5 on my new socket to A and B?
And how come when I took the back off the phone, I found four wires
connected inside it, although only 2 of them can be doing anything once they
get to the socket?
