Design of consumer units for amendment 3

[Guest666]

I can see different manufacturers will have their own interpretations and supply what they think is right , I heard the mention of wiska glands being used by some , I and others will just see what happens when it comes to it ...

The new amendment mentions nothing about cable entries into distribution boards over what has already been in previous versions of BS7671.

 

[Guest666]

Can you cite a reference for that?

Google lol.

Non-combustible material is a phrase used in many other industries long before the 3rd amendment was written.

 

[Leesparkykent]

Care to cite your references for that? Is it something the IET has published or is it a third party's interpretation/opinion?

The link in the OP.

Yes if is a phrase used in many industries, but that doesn't mean their definitions if it can be applied to bs7671.

So a third party and highly biased interpretation from a company which stands to profit from it. Not exactly the best source of useful information is it?

I really don't think they are going to change the meaning of English words though.

Is is this better from the Oxford dictionary:

Made of material that does not burn if exposed to fire; incombustible.

I don't understand what you are getting at TBH? I find the new reg about noncombustible DB's a load of bollox IMO. I just pointed out what 1 manufacturers stance was on the situation.

Well thats what we are discussing isn't it , thats what the op has posted ..lol...

I like the look of the Hagar boards.
I do believe they come with grommet strips (could be wrong).
They are made to be able to use different size trunking with the knock outs so that satisfies the IP issues and as said previously there is no provision needed to make the entries "fire sealed" as this is not mentioned in the new regulations.
Leesparky states the Beema reference which makes it clear what needs to be made and installed.
Also the cable clamps only come with the 30 version I think (could be wrong again) but sure it could be used in the 10 version.
The tails kit are great, used them for ages but it looks like they will not be used in the new boards.

That's no specific enough for this application of the phrase, the temperature the material is going to be exposed to needs to be defined.
Steel will burn if exposed to fire of sufficient temperature,

no, fire MIGHT cause steel to oxidize, depending on the alloy, but think of steel as a block of ice. Steel melts at 2800 degrees F and boils and evaporates at 5400 degrees. Some metals like magnesium can possibly catch fire but not steel

The IEE cannot just redefine the English language.

Leave steel in a forge for too long and it will be burning when you pull it out.

its a british standard mate, it over rules bs7671 as bs7671 is a guide and not statutory

wtf do you think the bs in bs7671 stands for?

 

[shanky887614]

the regs book is a guide not law.

like you bull$hit (british standarda obviously)

Your not allowed mate lol

Right so your post at 33 is a nonsense, you said a British standard overrules another British standard due to the fact British standards are non statutory.

But we are talking about a consumer unit????

 

[Leesparkykent]

Your not allowed mate lol

Obviously not lol, I now know for future reference haha.

 

[davesparks]

But we are talking about a consumer unit????

We are talking about a regulation which requires a non-combustible material, but offers no definition of non-combustible.
