    RCD keeps tripping

    Electricians

    My RCD keeps tripping and I can't find anything obvious that's doing it. Most of the appliances have been unplugged and I still can't figure it out. The entire system trips and not just a single fuse. Does anyone have any advice on how to find the fault?

    "Remove every single thing plugged in from the sockets and reset the RCD. Then plug things back in one by one and see if it trips."

    "Switch off all circuits then reinstate the RCD. The RCD should no longer trip. Then reinstate each individual circuit one by one and when switching up the faulty circuit RCD should trip. You now know what circuit is the cause of the issue. Leave that switched off and reinstate all other circuits. Check on fuse board to see what circuit is the issue. That will then narrow down your search as well as enabling other circuits."

    "First of all put all the small mcb down and unplug everything then turn the rcd up and hopefully it holds if it does then slowly start lighting up the mcb one at a time if it trips when you put a certain one up this will tell you what circuit Is the problem."

    "Nuisance tripping, faulty rcd. Water ingress somewhere, or mice somewhere, turn all circuit breakers off, see if rcd stays on, turn on 1 by 1 to eliminate."

    "Hi. You need first to locate the circuit (fuse) where the fault appears. Turn down all fuses, put up the RCD and one after another put up each fuse. That will indicate the fault circuit. Usually, there is a wire, box or something that is wrong."

    "You will have to unplug everything and turn everything off then see if still tripping if so a test for insulation resistance will need carried out at the consumer unit but you must be qualified and have the equipment to carry out this test sounds like you have a short in a cable or faulty socket, switches etc.
    The easiest way to repair is get a qualified electrician to check the fault out."

    "Take the neutrals out for every circuit on that side of the rcd. Keep all the mcbs off. Once you have taken out each neutral, switch the rcd to on and it’ll stay up, Touch the mistral bar with each disconnected neutral cable that you had previously disconnected and eventually the problematic circuit will knock out the rcd. You then know which circuit is causing the issue."

    "Hi, this could be the faulty RCD itself. They are only by manufacturer instructions supposed to trip a set amount of times. Difficult to answer without seeing this.

    What circuits are on the side that trip? Does the RCD cover all the circuits or is it a split board (2 RCDs covering two lots of circuits)

    The side that trips, does this by any chance have a light circuit on it? Or any outside lights?
