Anyone go the BBB to hand - reg regarding mix and match

[Octopus]

So next week I have to add a circuit to this board:

My plan is to add a Wylex breaker ........... but how would the BBB wording cover this?

I haven't bough the BBB yet!

After all, its not me that added the 3rd party breakers

There are a few cases, where one parent company owns more than one brand of component, where they may say yes but, in the vast majority of cases it's a liability that a company need not take on so, in all likelihood wont.

Proteus for instance used to make retrofit MCBs for Wylex rewirable and cartridge boards.
So maybe they were willing to accept the liability, or perhaps they conducted type testing?

Have asked this question of a manufacturer in the past.
Somewhere around 2003/4 I believe.
Think it was Proteus?

Only Proteus would recommend another manufacturers device for their boards to actually improve it

Brilliant line Westward.

think what pete means is that if you get confirmation from,say, wylex, that hager MCBs can be mixed in a wylex board, you're good to go.

Yes it does, short of taking on design responsibilities for the enclosure and components. I can't believe there are that many sparks who are qualified and experienced enough to take that responsibility on.

Perhaps if you were to read and inwardly digest the literature from manufacturers, you won't jump to to assumptions.

All the new regulation does is bring this into BS 7671 because the requirement in law was being ignored by sparks.

The legal requirement for type tested assemblies has been in place since 1994, so it's not new, it's just been ignored by electricians for the last 24 years and the "industry" is once again having to bring clauses into the BS to persuade electricians to comply with the law, which they should have been complying with for the last 24 years!

DBs don’t have to be type tested.
There has never been a law prohibiting the use of non type tested DBs and there has never been a law prohibiting modification of DBs.

 

[netblindpaul]

So, where does the Electrical Equipment Safety Regulations come in?
This is the UK implementation of the Low Voltage Directive.
Ok, technically you don’t have to type test, but, then, as the manufacturer of the assembly, you have to complete your technical file, proving that the equipment you have provided is as safe as if you had followed the requirements of the harmonised standard, which does require type testing.
Also don’t forget the UK ational annex.

My question is, if you arrive at a CU with preexisting mixed components can you carry out works on it?

Well ............... of course you can ........... why not?

A note on the cert is probably appropriate

If you don't do it, some one else will do.

Don’t get me wrong I also would but if by mixing components, without OEM approval, the cu is non-compliant.

Adding a new circuit to a non-complaint CU seems like it should be wrong.

Just thinking out loud to be honest.

It’s only your work that has to comply.
However you will have to take on board that the type testing has been voided, so any protective device you install will have to have a breaking capacity greater than the measured PFC.

Perhaps.

If I have learned one thing from this forum there seems to be a lot of notes on Certs going on.
