Determine the actual Zs of an A3 radial circuit wired in 2.5 mm2 PVC/PVC flat cable having a 1.5 mm2 CPC if its length of run is 40 m and it is installed in a location that will never exceed 30

 
Yes Matty - I was about to say that you hadn't included the Factor for 30 Degrees.

And that is what it probably is - I have no books to hand.

 
M4tty, I have also moved it to the correct forum.

May I also trouble you to put as much information as possible into the "Title" please?

This gets better Search Coverage and will help other people out too.

Many Thanks,

Admin.

 
correction factor for 30 degrees is 1.08
I think you are looking at the wrong table there Pat..

I read it as 1.04.
