Aluminium bar
sqmm and Copper is 1.6A per Sqmm.
Suppose we need bus bar for 630A, and we are going with
Aluminium bus bar
= 80*10*.8=640A
where 80*10 is size if bus bar usually available is the
market.
so we can use 80x10sqmm al. busbar per phase for 630A.
for TPN- (3.5)x80x10
If we are going with Copper bus bar
than we will use = 40x10sqmm per phase
= 40x10x1.6=640A
where 40*10 is size if bus bar usually available is the
market.
so we can use 40x10sqmm copper busbar per phase for 630A.
