can anyone pls expain me about how can we design a cable tray??suppose if have to draw a 3 nos of 50 sqmm AYFY and 2 nos of 35 SQmm of AYFY cable through the tray..how can we design the tray size?? regards...
3 4913if in 3-phase system voltage=440V,frequency=60Hz, current=400A. then if it is single phase then current=? and if it is single phasing then current=?
