I am after some help in calculating the curent carrying capacity of a ring final circuit wired in 16mm Tri rated singles!
From the book 16mm tri rated will take 100A. circuit no more than 10 meters long, all in steel trunking / DB enclosures etc.
Supplied from a Schnieder NSX160F with a 100 - 160A TMD unit.
I know there is a way of calculating this but for the life of me i cannot remember how to do it and no amount of Googling is being productive!
Some background on the reason - 8-row schneider Prisma panel with 6x 80A Multiclip bus bars. cannot wire each back seperatley without having 6 cables per phase at the MCCB so the thought was to wire a ring around the lot.
Any help would be greatly appreciated
