Moving Gas Earth-Bonding Cable

The regs do say that they are a minimum standard and they can be exceeded.

Sure - and, as I wrote, it's hard not to agree that 'best' practice is to never have unnecessary joints in any conductor - but we'[re talking about the regs, not Utopia.

 

[Murdochcat]

Indeed - so why did you suggest that it was BS7671 which needs one simple sentence of clarification?

Because with 1 simple additional this nonsense could be cleared up.

As it stands many people think that it does not need to be continuous and others say it does.

There are countless things that are not required by BS7671, as witness the fact that it does not say that they are required. A set of regulations cannot be expected to list everything which is not required, even if third parties are spreading misinformation.

BS7671 is a set of regulations (a.k.a 'requirements'). I'm not even sure how one would/could word a regulation that was indicating something that was not required!

As it stands many people think that it does not need to be continuous and others say it does.

The latter only if they are not properly conversant with what BS7671 actually does (and does not) require. ... and if they don't study and digest what BS7671 actually says, they probably wouldn't read your 'clarification', anyway!

So if none of it was ever in BS 7671 why do we waste customers money on this at all

BS7671 is just one standard among thousands.
It's not a document which covers all situations, and was never intended to be. It's a general purpose standard which covers electrical installations.

BS7671 states nothing about a looped bonding conductor being continuous.
BS7430 does, as it covers earthing of electrical installations in more detail than BS7671. It's approximately 100 pages long.

As other standards are ridiculously expensive, the IET and others have produced a whole range of guidance books, most of which have information from many other standards in them.

Of course BS 7430 itself states that it is almost entirely guidance and recommendation. There is not a single example of a 'shall' which relates to continuousness of earth cables in it.

And is that not still the way BS7671 is worded.

And is that not still the way BS7671 is worded.

Most of what is in BS7671reates to what is 'required' in order to be compliant with BS7671 (maybe I should say 'conformant', given BS7671's rather 'interesting' definition of 'con-compliance'!).

Of course,whether on not one wants, or necessarily even 'needs', to comply/conform with BS7671 is a different matter.
