Answer / sudhakar g

First you have to caluclate the load of the T/F i.e
KW=KVA*p.f
KW=500*0.8=400KW
I=kw*1000/1.732*415v*0.8
I=696.74 A
Based on these we can choose the Cable size ....
suppose the LT AL cable of 3.5c x 400 sqmm will give 530 A
of polycab....if we go for two runs of 400sq.mm means it is
good and the breaker size we will go for 800A ACB bresker
means it is good....

I am taking Electrical desining classes in Bangalore...It
will be usefull for designing as well as site engineers
those who are intrested to go for Electrical
Engineers....we give you indepth knowledge of Load calu,
Cable sizing, Lighting cal, panels, breaker
selection,Autocad drawing....if any body intrested means
