 That is a purely academic point. Reality varies with theory in many cases. We are talking about Chint here not Rolls Royce. This is a way to ensure makers' profits. Use our stuff only. I am sure that we are aware of that.

 

We can put our stuff into an empty enclosure or existing low Voltage assembly competently, so why not competently modify an existing assembly. 536.4.203 para 1. It is only a simple consumer unit so this is easily achieved.

 

Note 2. “Incorporated components inside the assembly can be from different manufacturers.”

Not really.

I would recommend you complete your reading of NOTE 2, because it goes on to say (my bold):

It is essential that all incorporated components should have had their compatibility for the final enclosed arrangements verified by the original manufacturer of the assembly and be assembled in accordance with their instructions e.g. the consumer unit, distribution board manufacturer. The original manufacturer is the organization that carried out the original design and the associated verification of the low voltage switchgear and controlgear assembly to the relevant part of the BS EN 61439 series. If an assembly deviates from its original manufacturer’s instructions, or includes components not included in the original verification, the person introducing the deviation becomes the original manufacturer with the corresponding obligations.

In other words, if you fit someone else's breaker, and the original manufacturer does not endorse it, you become the manufacturer of the assembly. Does your insurance cover for that outcome?

Yes Graham I read all of that. We as electricians all manufacture installations and assemblies, often with stull from different makers with no problems. It is all down to our qualifications and experience. Obviously the makers want us to use their stuff as it makes them income. Personally late on a dark rainy night if I had to get something up and running I would use my van stock and not worry about it at all. I must qualify that statement with the fact that I mainly undertake domestic work and small commercial and industrial work these days. With a new big project things may be different and I would take a different viewpoint. A person like you would specify the correct equipment to use. I respect that.
