Hi can anyone give me some advise.i have a socket fed from above on a ring main and a spur fed from that to a fan.i need to move socket 6 inches to the side.what is the best way of extending cables to do this was thinking of using wago connectors and box as it will need plastering afterwards. Do I need to extend all three wires or can I connect them in the wago box and just have 2 wires feeding new socket locations
