i have had a new mains board installed a few week ago everything was fine but now it trips every other night in the middle of the night i have nothing that comes on with a timer what could it be
rcd keeps tripping
- Thread starter John-tyler
- Start date
Who fitted the new board? What were the test results like?
a local spark i cant find the test paper at the min i will look for them are they needed?
Assuming he was competent, he wouldn't have left the installation with any problems that the test results would have shown up.
Have you put in any nails/screws in walls/floors/ceilings? Do you have any outdoor lights/sockets?

i got given a card from a friend so i just guessed he was competent he did give me a copy of test results what should i be looking to find on the test paper if its all ok i will post bk as soon as with the results

He shouldn't have changed the board if the test results showed up any faults plus the results will mean jack sh*t if you've put a nail through a cable or there is water getting into an outdoor light.

no i havent done any work in the house since he did the board
What about outdoor sockets/lights? The weather has been pretty bad recently, so a drop of water in a terminal block could be enough to trip the RCD.
Have you tried isolating any appliances connected to RCD protected circuits?

Intermittant RCD trips can be a nightmare to diagnose.
Firstly i would try unplugging or switching off using switches that are known to be double pole as much as possible overnight. Remember a neutral-earth fault can still trip a RCD even if the appliance is switched off by a single pole switch.
Failing that i'd say look at the usual suspects, inspect any outside wiring and get anything that stays on overnight PAT tested.

are we talking about the installation of new consumer unit? if so has RCB seperated and has he snapped the buzz bar in two parts so the higher voltage switches are on the right hand side and the low voltage on the left, this is what was causing mine to trip the electrician didnt do this on mine so I had him come out & check it

There isn't a high and low voltage section inside a consumer unit. I think you are confusing voltage with current. Plus, I can't imagine how your electrician managed to fit a complete busbar across the isolator, MCBs, RCD and then more MCB's without cutting it... Surely the neutral at the bottom of the RCD would have proved difficult to fit with a big big of copper in the way
Anywho, as I have now mentioned 3 times... Check outdoor lights/sockets and unplug certain appliances overnight until the tripping stops - when it does, you have found the culprit (hopefully)...
was the install rcd protected before?
newer rcd's are more sensitive than older ones..
is there any industry local to you that works nights?
do you have air conditioning installed?
do you have your heating set to night mode? ( comes on if the temp drops below a level.. )
have you bought any new equipment recently?
