Same current with flat and trefoil single core cable layout

[Simon_Hvid]

Hi

I get the same current carying capacities when i chose trefoil (663A) and flat (694A) formation with a 400mm2 AL in cable ladder.
As i understand these 2 currents should be different, in regard to 60364 B.52.13

Can anyone confirm a this too in version 5.1.0 of Ecostruxure Power Design?

Hello Simon

Thanks for reaching the EcoStruxure Power Design Forum.

As you expressed, the current carrying capacities for the arrangements “Flat touching” & “Trefoil” should be different.

This regressing issue has been reported to the product development team.

This should be fixed during the next release.

We will keep you informed, once the fix is available at the release.

Thank you,
