formula for cable size calculation for current?
Answer Posted / gurunadharaov
by the formula p=v*i*cos@
assume the load as 5kw and operating at 230v and also
assume the load as inductive (so the power factor is 0.5
pf lag)
now by formula
5000=230*i*0.5
i=50A
NOW CABLE SIZE MUST BE > LOAD
SO CABLE SIZE IZ 65SQMM(ITZ DSSEPEND ON AL/CU CABLE)
