My house had a new consumer unit fitted in 2005 it's partly fitted with RCBOs and partly with MCBs it was installed by the DNO who are SSE in this area bearing in mind the year it was installed are the rcd fitted likely to be electronic type or plain electromechanical ones I'm asking out of curiosity because if ever there's a fault in my workshop ( for this read that I make a mistake or an error when experimenting) usually the house RCD trips despite me having an electronic plug in one on my test bench supply which I think should fire first ide really appreciate your wise words on this thanks x Kelly
