[QUOTE="Traineeboy, post: 519545, member: 32807"] Is it possible to add a non protected MCB to a duel RCD Board. A non protected circuit would serve a mini garage board that has its own RCD. The chap i was with today was quoting to put a garage feed up to the top of the garage. He said that as they have a Duel RCD board it can’t be done and they would need to change the board. Really ? Would it not be acceptable to have a MCB next to the main switch ( linked with a piece of busbar) and the incoming line obviously going into the top of the MCB, but the questions is where would incoming neutral go as there is only 2 N bars not 3 as it’s only a duel RCD board. Can it be done properly or would the board have to be changed ? Thoughts [/QUOTE]
