I’m replacing an unswitched socket for a flat plate switched which I will also replace the back box to a 35mm for. I haven’t fully taken off the old one yet just unscrewed it so I can take a look at the wiring. Not the greatest pic I know but does this wiring look ok, seems to be two red & two black coming from those two separate white sleeves & one earth connected with the other seeming to have been cut. Also would it be ok to put these wires into a terminal block & turning electric back on if needed, if so which rating block to use?
