mcb trips..

[kuksiani]

i have install 18 way CU but im so surprised why one MCB trips every time when i switch on main switch..just one of them..he does have any problem on cable installation and not trip after i switch on again..if i switch of main switch and i switch on again that MCB trips..its brand new installation , CU and MCB..another strange problem its the consumer unit make noise..its not like usually noise of transformer do..its like PIIIIIIIIIIIIIIIIIIIIII..i never heard that before..its first time for me..any sugestion why MSB trips and why CU make noise...

I first do the bang test, is fine, then I do big money test is also fine.

Bang test not fine, he say bang test make small switch next to big switch go mini bang?

 

[telectrix]

only 3 possibilities.

1. fault on circiut.

2. faulty MCB.

3. faulty electrician.

No, if you have test result of bang-bang then your board is chitty?

4. 1, 2 & 3 combined

Mathematically speaking, 1 & 2 are both products of 3, so must be 3.

And with 13 years experience you would have thought that this would be water off a ducks back.

LOL - have a look back through the OP's posts list.....doesn't exactly inspire me with confidence!!!

Oh look, someone's come on our forum looking for help, but they dont know the correct terminology or questions to ask, I know, lets take the mick, that will help. Not.

What is the circuit supplying? If it is something with a high inductance like lights or a motor then this could make it trip.

No; someone had come onto the board asking firstly questions about some 'big house rewire' followed by questions on 'how to move a consumer unit' followed by 'it's all gone wrong and I'm in the ---- with the customer'.

That isn't an issue of not knowing terminology (that happens to us all occasionally, it's a big world of electrickery out there), it's an issue of being under-trained and incompetent and thinking that Google can make the world a safer place by coming somewhere like here and posting questions to people who ARE competent.

The OP deserves the contempt he gets.

The original post is nonsensical. He got what he deserved, a ribbing. Happy to help but you have to understand the question first?

If had asked...
New domestic installation, I've fitted the CU and energised after inspecting and testing the whole installation. Weirdly 1 sole MCB keeps doing xyz when the main switch is turned on and off and I'm at a loss to understand why. Here's my test results... Please could someone offer some advice?

First off, we'd have understood what was being asked and secondly he'd have got positive replies?

First off, we'd have understood what was being asked and secondly he'd have got positive replies? And thirdly, would have demonstrated some competence and understanding of the basics.

If he was fully trained and competent I dont think he'd be on here asking for advice, do you.

This has got to be a wind up right,please somebody tell me it is,just looked at his other posts and if it ain't a wind up then it's very worrying.just the type of situation we all say needs stopping.

Ergo, if he ISN'T trained and competent, what the hell is he doing in someone's house charging them money for being a chancer??!!
