The first thing I notice is you are squaring the diameter, not the radius. They are getting around this by using 3.14/4 (.785) instead of pi. Try it using .25 for the radius, squaring that and multiplying it by 3.14

If I was being lazy or didn't have a calculator I would look at table 5, pick a conductor the size of my cable (in your case 2/0 TFE,PFA,PFAH,Z is close enough for guv'mint work at .508), then use the conduit fill table in annex C.

Hi, Thanks for the reply. I did that already but I know that there are different calcs for straight runs or runs with conduit bends and maybe some other factors I am not quite sure on when dealing with this type of cable.
The calculation I did was from a recent thread in the forum on the same subject.
I will look at the calculation again.
I am not sure if it is right.
