[QUOTE="PC Electrics, post: 81780, member: 650"] Just done exactly this myself. RCD kept tripping at complete random. No faults found on circuits on either side of board. Used mA meter to find installation (with appliances plugged in and on) had a total leakage of 5.5mA to earth - not enough to trouble a (healthy) 30mA RCD, so came to conclusion RCD is at fault. Just waiting for new RCD now. I use a Rapitest multimeter - they sell them at B&Q, about [/QUOTE]
