The wire sizing calculator considers copper conductors only.

The short circuit current and clearing time for the protection device. I think the curves are from ICEA. The current rating is based p3-2-382 the insulation type. On low voltage circuits the let-through current is typically used, i. For higher temperatures, a derating will have to be applied according to NEC. I take this to say PVC thermoplastic has the same damage p-32-328, no matter what the continuous rating is.

The three phase AC voltage drop is calculated as: Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework.

Load kW, kVA, A, hp: I suppose using 90C cont. Specify the voltage and select the phase arrangement: Students Click Here Join Us! The maximum allowable voltage drop. The estimated cable or wire length in p-32-82 of feet Short circuit current and time kA, ms: Resources Few production environments have the luxury of ordering new equipment to replace existing machines on their shop floor. And that the raceways, cables and buried conductors are spaced according to NEC to prenet derating.


Such issues are the result of project complexity, size, uniqueness and regulation, as well as the need for virtual team icra.


Due to heat conduction in the copper, I may have a cable p-32–382 at 90C all the way into the breaker, depending on whether I can assume the cable cools off in p-32382 distance distance between the exit from the conduit and the point where it reaches the breaker.

I called them on the matter yesterday, but no response yet. How the conductors are in installed. More than one cable may be selected for high load scenarios. The single phase AC voltage drop is calculated as: It is done all the time. The Eng-Tips staff will check this out and take appropriate action.

I dug up the buff book and it says the same thing.

Normally the terminations are rated for a maximum of 75 deg C ratings. Are you an Engineering professional?

I don’t think I’ve seen a minimum length specified anywhere. Download Now The Architecture, Engineering and Construction AEC industry is constantly looking for process improvements to better manage potential project delays and costs.


This is not considered in this version of the calculator. There is absolutely no problem in using 90 deg C insulation at 75 deg C ampacity. Close this window and log in.

Register now while it’s still free! If I run A into it, it seems I can assume that the cable is running at 90C down in the conduit.

Everything thus far points to C as the damage point for typical PVC insulation. The values in Table 9 is based om three single conductors in a conduit. A is the conductor area in circular mils.

SKM has buried in thier default databases a damage temperature for cable of C, yet I can find no backup for it. The current rating -p32-382 also based on installation method.

Is time a loom, weaving all together, or a broom, sweeping all away? This only applies to thermoplastic insulation. Thanks to everyone; I consider my question answered. The wire sizing calculator uses the resistance and reactance values from the PVC conduit column in chapter 9. The -p32-382 part p-32-32 to select the correct temperature rating.
