I would like to RCD protect an existing cooker socket circuit in the kitchen. There is no room in the existing CU to add the RCD. So can i set up an RCBO in a new box, right next to the existing one, run a suitably sized cable, not tails, from the existing MCB to the new RCBO in the new "extended CU" and then power to the cooker from there.
Thanks for your help
