Hi all just a small question can some one just check my working out

Ib. = 30

In = 32

It = 24a

Iz=62a.

Ca=0.79

Cg=0.60

Is the IT. 24a. Right or am I missing some thing just seams a bit low

Thanks.

 
poni thanks for that

i have bean deviding the

In =32

not the Iz=62             done it 3 times        .

thanks again

 
sorry I may have to start over

is the 62A the rating of the cable from the tables, if it is then 29A is the max current it will carry with 0.6 and 0.79.

the correct way to do this is to start with the fuse (32A/0.6/0.79= 67.5A )then look for a cable with a current carrying bigger then this
