Help!.
I changed the CU in my house to dual RCD split board, as many of you know. All tests were fine and everything has been working perfectly in the 2 or 3 weeks since the installation.
Now for the last 2 nights the RCD on one side of the board is tripping in the dead of the night. It literally happens when pretty much nothing is on in the house (just the wireless router and TVs etc on standby).
The RCD is a 30mA / 80A Wylex.
Any ideas as to what may be causing this? Is it possible the RCD is faulty? I considered this but thought it rather strange that the thing only tripped in the wee small hours and not when stuff was actually being used.
I do know for a fact that I have a bit of a mouse issue at the mo and the poison and traps have been set, so hopefully wont have for much longer. The timing of the tripping is certainly in keeping with the hours that mice are awake. Has anyone come across this problem before?
Any suggestions as to where to start to sort this out.
I'll quickly add that thee are only 3 circuits protected by this RCD. The final ring, the radial to the immersion and the lighting. These are all existing circuits in the house and have never been RCD protected up until 3 weeks ago when I fitted the new CU. The three new circuits on the other side of the board are not causing any problems at all.
Should my first port of call be to change the RCD? Should I move circuits 1 by 1 over to the other side of the board to see if the other RCD trips (hence identifying the problem circuit)?
