rcd keeps tripping nothing plugged in - please help!

alexrobinson101

On Saturday night about 1am (give or take a couple of hours) our RCD tripped, if we turn the socket breaker off then the main RCD will stay on, (lights kitchen etc) Our kitchen units are on a separate breaker so it won’t be the fridge/freezer.

We have unplugged all appliances taken out all the fuses from spurs (To our knowledge) and it still trips when nothing is plugged in,

Before we get an electicrian to rip open the walls to check cabling does anyone know anything else we could do? Any help is greatly appreciated.

Boiler? Immersion? Pond pump?

Could be literally hundreds of things

Keep thinking...

Without testing it is difficult to tell what the problem will be. However it might be a faulty trip (tripping when it ought not to do but that is unlikely, especially as it does not trip with a particular circuit switched off).

If you have absolutely nothing connected to the tripping circuit (double check?) then an electrician is best called in to test and then take it from there.

The fact that there is nothing connected to the sockets or fuses removed does not obviate a fault. It could well be within the cabling (as you fear) or a problem with low insulation resistance with the loads on the circuits with the fuses removed. You really need to totally disconnect rather than pulling fuses that are probably only on the live wires, leaving any neutral-earth fault still connected.

Do you by any chance have a cat?

I had this problem a few years ago and it turned out that the cat I had at the time decided to spray into one of the sockets.
After doing a search on Google, it appears that this is a fairly common problem.
