I have a fairly modern consumer unit with mcb's and and an rcd. Tonight the rcd tripped and I have tracked the problem down to one particular circuit. Everything is fine when that mcb is switched off, but when it is switched on the rcd won't switch on at all. I unplugged every appliance that was on that circuit, but the problem is still there. No electrical work or DIY has been done recently.
Does this sound like a faulty circuit, and if so why should it suddenly occur out of the blue as it were
Thanks in advance for any help
