I just fitted a new RCD Cu and the ring, and lights etc trip the RCD when powered up. The only things that don't trip it are the new shower circuit, the emmersor and the power to the heating timer. The ring trips it and so does the lighting when powered. I've had to modify the board so that the RCD only does the shower for now but I'd like to have my sockets on it too and perhaps the lighting. It's a 2 bedroom house from about the 70's with original wiring I'd say.
