Answer Posted / jack
For 35mmsq size cable ,current anything more than 150
ampers is applicable.To find current use the formula P=VI
COSfi,WHERE COSfi=0.8 ,from this find current I,to find the
cicuit breaker size use the formula c.b rating =I(1.1-
1.25) ,this will give the ciucit breaker size,
Cuurent (amp) Cable Size (mmsq)
10 1.5
25 6
50 15
100 25
150+ 35
