How can w select the cable size for different rating load
& also waht r factors affecting the during selection of
cable?
Answer Posted / rathinam
My point of view, To find the cable size need to divide the
LOAD CURRENT by 3.
i.e:
Cable size= Load current (10A)/ 3
= 3.3
Now the answer is 3.3, But we don't have the 3.3 size of
cable. so we can choose next related size of cable, which
is 4 sq.mm.
