[IEC 61439 for LV equipment April 16th 2020 webinar] - diversity factor

[PascalL]

Question from Conrad:

Is the rated diversity factor applicable for sizing the main horizontal busbar?

[PascalL · Accepted solution]

Hello,

Based on markets (buildings or critical sites), Most of customers prefer to keep the cross section for the full current or to have the same or above current busbar compare to the main incoming section.

The diversity factor is mainly used to distribution busbar

Because we know the loads and so the rating of the different outgoing running at the same time. 

In that case we case define and use a diversity factor.
