Hi Andy

The values were just picked out of the air by the lecturer, it was so
that the class could work through correction factors, finding out Zs,
fault currents and selecting cable sizes.
I think he left out all the details so that our poor little brains
don't overload :-), but the values he used cause more problem in the
end.

Thanks for information, helps move class room knowledge to the real
world (Even if the above example would never happen).
