I dug up the buff book and it says the same thing. Maybe it’s assumed to be sufficient if adequate wire bending space is provided per code.

Ocea that the raceways, cables and buried conductors are spaced according to NEC to prenet derating.

I called them icae the matter yesterday, but no response yet. Currently supports AC only. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework.

Due to heat conduction in the copper, I may have a cable running at 90C all the way into the breaker, depending icfa 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. The important part is to select the correct temperature rating.

If you’re planning to load V cables up to their 90 deg C ratings, better take another look.

Download Now Defense manufacturing is all about project manufacturing and project accounting. If I derate the entire cable down from A down to A, I can assume the cable runs at 75C down o-32-382 the conduit, and hence the breaker is not at risk of seeing hot ices. Load kW, kVA, A, hp: The short circuit current and clearing time for the protection device. Furthermore, high voltage circuit breakers typically do not limit the fault current.

It is done all the time. Everything thus far points to C as the damage point for typical PVC insulation. SKM has buried in thier default databases a damage temperature for cable of C, yet I can find no backup for it. To apply a manual derating, divide the load by the derating factor from NEC, and enter the new load value in the calculator.

The short p-32-3882 capacity is calculated as: This method calculates the impedance for the worse case power factor, i. The estimated cable or wire length in meters of feet Short circuit current and time kA, ms: More than one cable may be selected for high load scenarios. The current rating is also based on installation method. It’s easy to join and it’s free. For higher temperatures, a derating will have to be applied according to NEC. The current rating is based on the insulation type.

This will affect the derating of p3-2-382 cables. Download Now White Paper: Red Flag This Post Please let us know here why this post is inappropriate. This only applies to thermoplastic insulation. The values in Table 9 is based om three single conductors in a conduit.

I think the curves are from ICEA. As dpc notes, you are often limited by terminations for continuous loading capacity.
