Hi,
I looking for a procedure to performing cable (high voltage xlpe) ampacity calculations by hand; a worked example would be perfect.

Thanks,
Dan.

See NEC 310.15(C) for the equation. There are some examples in the back of the NEC in Annex B.
Is work slow in Trinidad? The equation shown is the Neher-McGrath equation.
It looks simple but it is a 100 time more complex that it looks. That's why engineers use a software program to do the calculation for then. Do a google search for Neher-McGrath equation.
 
No Sir, work isn't slow. I just prefer to do it by hand at least once, and right now I?m doing it out of pure interest.

Thanks.
