nos of 35 SQmm of AYFY cable through the tray..how can we
design the tray size?? regards...

Answer Posted / 7anoter4

For open top solid bottom cable tray and without any
clearance between cables the cable carrying capacity
has to be reduced to 73%. However the tray width will be
only:
0.3*34+34+34+34+30+30+0.3*30=181.2 mm
3*50+ 117*.73= 85.4 A ; 3*35+ 96*.73=70 A
