Rcd Issues With Tripping

[arcadejay]

I would if someone could give me some advice. I have had an issue with my RcdTripping today.i did the usual tripping each trip one at a time until finding which causes the RCD to trip. I located the trip that was causing the problem and after a couple of resets it stayed in. Later in the day it went again but this was a different trip on different circuit. And again later it tripped but a different trip on a different circuit. Could this be the RCD failing? Or could there be an neutral issue qnd could this effect different trips?

Thank jason

Probably not and yes

Unfortunately, for you, you really need to get someone in to find this fault as it'll more than likely take some proper testing to find

Welcome to the forum, from your post all you have done so far is switch MCB's and RCD's off and on until they all stay on. You haven't actually located the cause of any fault, disconnected it, or repaired it. Therefore I would suggest that the RCD is most probably operating correctly and detecting the same fault that you haven't yet rectified. If there is a neutral issue your testing method proves nothing as MCB's will only disconnect the live. Or you could have a cumulative leakage problem that only trips once several circuits are drawing more current, again your testing method would not identify this. We need to know the actual operating characteristics of the RCD, i.e. its trip times and ramp test trip current to establish if the RCD is giving any false trips. Then we would need to know when the cables were last fully tested, there insulation resistance vales with all accessories disconnected to establish if there are any cable damage issues. Then you would be looking at your various accessories and appliances connected.  As has been said it may work out quicker and cheaper in the long run to get an electrician to come and to some checks with proper test equipment.
