Three plus one 'going back into it' equals 4, doesn't it? More to the point, it's crazy! You really ought to get an electrician to sort that mess out.No socket has 4 cables in it. It had 3 in it and still has 3 now because 1 was took out to go in junction box and ringed back into that socket.
Kind Regards, John.
Jimmy the electrician was there a few minutes ago - he tested it and left his business card as well. So it must be correct mustn't it.
Well it works.
