New kitchen, live earth fault!!

[Darkwood]

A N/E fault still warrants rectification before its energised, considering there has been a board change, all circuits should have been tested prior to the change and any issues included in the quote for the work, to find a fault then re-energise it after the board change is arris about face and poor work ethics from any supposed qualified competent electrician.

Thank very much for all your help and advice, these lads genuinely want to resolve the problem, although some critical and concerning comments, I will show them this thread, a friend kindly suggested posting on here for independent thoughts and advice.
Please keep posting more thoughts and comments.

I suspect the neutral/earth fault is existing and has nothing to do with the kitchen frolics.

 

[Darkwood]

Please give us any feedback, as regards my comments and to further your understanding, a N/E fault more than often won't pose an actual risk to yourself as such but there are situations where a N/E fault is definately a cause for concern, this cannot be comfirmed with just a meter reading and requires further investigation hence my concerns that it has been re-energised although I am in the party of thinking that any N/E fault should not be energised until it has been corrected regardless whether the fault was new or pre-existing.

Thanks again, and I will certainly reply to let you know the outcome.

Is it just me or is the r2 for the RFCs too low, measuring bonding or a fault or ... And the R1+R2 for the RFCs (neatly typed in the R1+R1 column ...) is too high ?

In all honesty, the lads who genuinely want to resolve this problem shouldn't of been touching electrics in the first instance.
You should pay for a registered Electrician to come out and find the issues, put them right and then you should counter charge.

I would be interested to compare actual readings with those on the cert.

Wonder what the scope or description of works says on the first page?

I was thinking the r2 is too low

As already said , tell them you will employ an independent electrician in if the problems not sorted , which may be a you're best bet in the long run anyway..

They probably did not mention the neutral to earth fault as the schdule does not have a box for N/E insulation test results.
Wonder why the shower is on a 5 sec dis ?
Type (Type )MCB s theses must be new!

On a serious note putting the up sockets on the non RCD side of the board is unaccepable and fobbing you off saying badly wired plug ,they new the fault was there when or if they tested (might of been RCD not holding test when energised) as all plugs etc should of been removed for testing!

Cash in hand or whatever method of payment the elctrician has changed the CU and has to do this as per the current regulations!

A few tests prior to the CU being changed would of identified any IR problems and I wonder if the house has a borrowed neutral what with both lighting ccts on the same RCD.

A picture of the inside of the consumer unit would be good!

I do hope this issue is resolved sooner rather than later let us know!

just to throw a spanner in works type b32 max z s 1.37 not 1.10 on test sheet still on which regs did get the maxs from ?

??? Yes it does. The n is a live conductor, the lowest result goes in the live / earth box

Because it's above 32a would be my guess....

1.37 x .8 = 1.10

@mhar - When filling out test sheets, it asks for the max permitted value as stated by the BS7671 not the adjusted value for temp' compensation that the onsite guide gives you.

 

[Octopus]

So the upstairs sockets aren't protected by a RCD - why not? The installation doesn't comply with the regs....

Back to the OP - this is where you need to get an answer from the people that installed the CU........

Hi DW and MHAR - These days I put a clarifying comment in case Inspector Clouseau wants to look. Hopefully readers are aware of the need for the 2 values.
Cheeky Comment : As the OSG values seem calculated by applying BYB Appendix 14 to Table 41.3, l guess you could say it was the max value from BYB ?

The fact that the test results bear almost no relation to what is installed and written on the consumer unit is very suspicious.

The fact there is a neutral-earth fault on the upstairs sockets may mean that any leakage could be passing through the earth bar of the consumer unit and then passing along the bonding cable and onto the gas pipe. We don't know if the consumer unit is properly earthed do we?

I hope this gets sorted
