I half-finished a sentence in my last post. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. The Eng-Tips staff will check this out and take appropriate action. The customer asked me to put cable damage curves on the TCCs.

Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. On high voltage circuits the prospective fault current is typically used i.
Red Flag This Post Please let us know here why this post is inappropriate. For higher temperatures, a derating will have to be applied according to NEC. Is time a loom, weaving all together, or a broom, sweeping all away? The wire sizing calculator uses the resistance and reactance values from the PVC conduit column in chapter 9. Icez should icda written, “An engineer from Southwire emailed me some pages out of iceaa Southwire cable manual that says PVC insulation is rated only to C.
As dpc notes, you are often limited by terminations for continuous loading capacity. Ignore the neutral and earth conductor in three phase cables. Thank you for helping keep Eng-Tips Forums free from inappropriate posts. Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden. The short circuit capacity is calculated as: Both dpc and jghrist flag a problem I have on how to derate cable: Thanks for pointing out the breaker termination as a limiting factor, and I have to check that I do not have some higher temp cable in the mix, such as XHHW.
Thanks; that gives me a good resource. Download Ciea Defense manufacturing is p-32-82 about project manufacturing and project accounting.
The current rating is also based on installation p-32-3822. I think the curves are from ICEA. If you are limited by fault current capacity, XHHW might be a good choice. It is assumed that there is only one three current carrying conductors in a raceway, cable or buried.
The important part is to select the correct temperature rating. I called them on the matter yesterday, but no response yet. SKM has buried in thier default databases a damage temperature for cable of C, yet I can find no backup for it. Close this window and log in. Specify the voltage and select the phase arrangement: The impedance is calculated as: By joining you are opting in to receive e-mail.
THHN/THWN 90C Damage Curve – Electric power & transmission & distribution – Eng-Tips
If I run A into it, it seems I can assume that the cable is running at 90C down in the conduit. If you’re planning to load V cables up to their 90 deg C ratings, better take another look. Click Here to join Eng-Tips and talk with other members! Are you an Engineering professional? More than one cable may be selected for high load scenarios. It’s easy to join and it’s free.

Currently supports AC only. This is not considered in this version of the calculator. Register now while it’s still free! Normally the terminations are rated for a maximum of 75 deg C ratings. Everything thus far points to C as the damage icwa for typical PVC insulation.
