The house we are in currently has no 6mm stove cable connection in use. There is a piece of cable going through a passage ceiling and into the ceiling space of the kitchen but it is too short for its location and it is not connected to the distribution board. The question is - is it feasible to use this cable and extend it on either side using a chocbox and block connector, or is it necessary to run a complete new cable (which is impossible I think). Appreciate any comments as to what the relevant rules would say.
