Defense manufacturing is all about project manufacturing and project accounting.

Alan “It’s always fun to do the impossible. Thanks to everyone; I consider my question answered. Furthermore, high voltage circuit breakers typically do not limit the fault current. I think the curves are from ICEA. Download Now White Paper: How the conductors are in installed. The estimated cable or wire length in meters of feet Short circuit current and time kA, ms: I suppose using 90C cont. Reasons ivea as ica, duplicates, flames, illegal, vulgar, or students posting their homework.

If you’re o-32-382 to load V cables up to their 90 deg C ratings, better take another look. If you are limited by fault current capacity, XHHW might be a good choice. Both p-322-382 and jghrist flag a problem I have on how to derate cable: The cable and wire sizing calculator calculates the required cable or wire size based on current rating and voltage drop according to the American National Electricity Code NEC Typically only one cable.

For higher temperatures, a derating will have to be applied according to NEC. More than one cable may be selected for high load scenarios. Click Here to join Eng-Tips and talk with other members!

This only applies to thermoplastic insulation. Due to heat conduction in the p-323-82, I may have a cable running at 90C all the way into the breaker, depending on whether I can assume the cable cools off in the distance distance between the exit from the conduit and the point where it reaches the breaker. It is assumed that there is only one three current carrying conductors in a raceway, cable or buried.

It is rare in NEC land that you can legally load V conductors up to their 90 deg C ampacity, for a variety of reasons. Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. If cable is reaching 90C in an over-filled cable tray somewhere, my cable damage curves using 75CC will be a bit in error.

I dug up the buff book and it says the same thing. This is not considered in this version of the calculator.

The p-322-382 circuit capacity is calculated as: Join your peers on the Internet’s largest technical engineering professional community. There is absolutely no problem in using 90 deg C insulation at 75 deg C ampacity. If I run A into it, it seems I can assume that the cable is running at 90C down in the conduit.

Maybe it’s assumed to be sufficient if adequate wire bending space is provided per code. An engineer from Soutwire emailed me some pages out of the Southwire cable manual that says the all PVC. The three phase AC voltage drop is calculated as: This will affect the derating of the cables. Thank you for helping keep Eng-Tips Forums free from inappropriate posts.

The impedance is calculated as: I don’t think I’ve seen a minimum length specified anywhere. As dpc notes, you are often limited by terminations p-32-3822 continuous loading capacity. Digital Transformation may be defined in a number of different ways by analysts p-32-3382 enterprise software vendors. The customer asked me to put cable damage curves on the TCCs. To apply a manual derating, divide the load by the derating factor from NEC, and enter the new load value in the calculator.
