Bonding issues - yes or no

I presume you know what the definition of an extraneous conductive part is?
I would presume (hope) that he must do - he's doing EICRs!
LOL. I wasn't aware that there was a pre-requisite to be familiar with BS 7671:2008 (2015) or sometimes even to possess appropriate test instruments :!:
Well, there may be no rule or regulation which specifies such requirements, but ..... :-)

I would also presume that editions of the regs far longer in the tooth than BS7671:2008 (2015) would provide a (still up-to-date now) definition of an extraneous-c-p!

Kind Regards, John

Indeed. For some it doesn't appear to be necessary to have been familiar with any Edition or Amendment though!

Quite - as I said, I'm not aware of any regulatory or Statutory requirements. AFAIAA, I could undertake an EICR if I wanted to and, although I am reasonably familiar with BS7671, and have the necessary test equipment (and know how to use it and interpret the results), that would be where my 'qualifications' to do it would stop!

Sorry if I am not explaining this very well,

The mains water is not bonded, it is fed from led pipe then converts to copper into the cupboard in the kitchen, the copper pipes are basically only in the cupboard feeding the tank before dropping off and changing into plastic,

The builders said 2 sparkies and a lecturer have said it doesn't need bonding as there is not enough copper present

I disagree and will not issue a satisfactory until I am proved wrong or the bond is installed

Because my answers are not full cut and paste answers from bs7671 you should not assume that I do not understand because of a simple answer, this is a forum for electricians? Yes the pipe does extend outside the property, but extraneous parts do not need to.

My worry was that I wrong because of the amount of copper and I can not find any reference to this?
 
Have you tried to prove whether the pipe is extraneous or not? If not then this is a pointless discussion.

It surely should be bonded, so that would seem to be one 'unsatisfatory' thing for you to code on your EICR?
The builders said 2 sparkies and a lecturer have said it doesn't need bonding as there is not enough copper present
I would suggest that you should ask what on earth these "2 sparkies and a lecturer" are talking about...

You have no need to worry. You won't find any reference to "the amount of copper", since that is totally irrelevant in terms of whether or not bonding is required!
I disagree and will not issue a satisfactory until I am proved wrong or the bond is installed
As above, if there is an incoming water service in metal pipe that is not bonded, you certainly could not issue a 'satisfactory' EICR. The business about 'amount of copper' is nonsense, but it could well be that the pipes you are concerned about do not need bonding (because they are not extraneous-c-ps), so that may not be a reason for not issuing a 'satisfactory' EICR.

No I haven't so ok I'm being an idiot but, is there anything that says an extraneous part doesn't need bonding if it is of a certain size? That is what I'm trying to ask
 
I always hate getting involved with builders who's 'electrician' has disappeared before the testing was done.
 
is there anything that says an extraneous part doesn't need bonding if it is of a certain size?
No, as looking in your copy of BS 7671 will confirm (and should be your first point of reference).

But the fact remains that we cannot say whether or not the pipes are indeed extraneous. You are the person on site - you prove this one way or the other.
 
From the clearer information now given I would say that main bonding is required.
It would be interesting to discover why the others decided it was not.


It is recommended that flats not on the ground floor have their supply bonded as even if NOT an extraneous-c-p to the building they could be to the flat.
Plus, if not actually an e-c-p to the premises, but because it may be connected to the CPCs bonding should be applied as it will do no harm.

So all you would be able to do is prove it was not an e-c-p but this is unlikely.
