The IEC 61439 part 0 talks about specifying rated diversity factor ( suiting a particular application) for the whole assembly or for group of circuits .

It also defines rated diversity factor for a whole assembly as the average loading conditions for which the assembly is designed . If the rated diversity factor of the assembly is say 0.8 then it means any combination of outgoing circuits can be loaded to 80% of their rated current , provided the total load on the o/g circuits do not exceed rated current of the assembly.

My question is how to specify the RDF in a tender specification ? What is the rated diversity factor of BLOKSET and PRISMA LV switchboards ? Can i use this as a differentiating factor and winning spec for Blokset and Prisma
