Strange fault

[bodders22]

Hi All,

I was called out yesterday to a customer that has been having trouble with the electric tripping on various circuits (16th edition mem2000 board)
When I got there I had a quick look and couldn't find anything obvious anyway cut a long story short did a full eicr, all circuits good.
She's phoned the dno no reported problems in the area.
Ive explained it's probably something they're using as it never trips when they're out, or maybe could be a water leak after a shower etc, but still no pattern.
I've isolated the outside lights and it still occurred last night.
The strange bit though is its the non rcd side and she's claiming the main switch tripped along with some mcb's.
I thought perhaps a faulty switch so replaced with one I had in the van but as I said it happened again ! Is this possible as I've never come across a switch that switches itself off and no its definatley not an rcd. It's 1990's house and doesn't appear to have been messed around with too much.
Confused please help!!
:rolleyes4:

My mum caught me trying to stick a nail into a 13A socket outlet when I was a toddler, gave her a bit of a freight!

Some kids are just born bad or uncaring (sociopathic). I've seen them grow up with firm but fair parents, being set goals and not mistreated at all. Then you find that they have carried out horrendous things.
I agree that most of the time, it's poor upbringing.

Ah, the old Nuture v Nature debate...difficult one!
Too many variables and the inability to have a 'Control' sample to come to a conclusive answer.

The question here is why the heck would she flick the switch? especially this many times and not say anything :/ how old is the daughter out of curiosity?

The daughter is about 11, it only happens when she is up, nothing happens when there all in bed.
Just found out there is a new man on the scene enough of a trigger maybe ?

New man on the scene - it's you isn't it?!

I would say 'I wish' but dunno what the mum looks like!

Mixed up neutrals between RCD/non RCD sides ..... or a borrowed neutral upstairs-downstairs lights?

Odd statement if you read the whole thread

didn't read all the posts so sorry if this has been said before but my idea would be to put a tamper proof seal on the cover of the CCU.

if the main switch go's off while the seal is intact get straight on the phone to Derrick acorah
