Rated diversity factor

In reality all circuits within an assembly will not be called upon to carry

their rated current simultaneously and continuously. Diversity is the

 proportion of their rated current each circuit within a group of outgoing

 circuits or all outgoing circuits within the assembly can carry,

 continuously and simultaneously, without the assembly overheating. In

 the absence of any other information in the assembly specification the

 manufacturer will assume the standard diversity factors for the whole

 assembly.

 

Typical RDF

Number of main outgoing circuits	Diversity factor
2 and 3	0.9
4 and 5	0.8
6 to 9 inclusive	0.7
10 and more	0.6
