Due to heat conduction in the copper, 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. I should have written, “An engineer from Southwire emailed me some pages out of the Southwire cable manual that says PVC insulation is rated only to C.

Thanks; that gives me a good resource. The single phase AC voltage drop is calculated as: Promoting, selling, recruiting, coursework and icsa posting is forbidden.

Thanks to everyone; I consider my question answered. How the conductors are in installed. Join your peers on the Internet’s largest technical engineering professional community. On high voltage circuits the prospective fault current is typically used i.

The three phase AC voltage drop is calculated as: If I derate the entire cable down from A down to A, I can assume the cable runs at 75C down in the conduit, and hence the breaker is not at risk of seeing hot conductors. More than one cable may be selected for high load scenarios. I don’t think I’ve seen a minimum length specified anywhere.

If you are limited by fault current capacity, XHHW might be a good choice. 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.

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.

Specify the voltage and select the phase arrangement: If you’re planning to load V cables up to their 90 deg C ratings, better take another look. If cable is reaching 90C in an over-filled cable tray somewhere, my cable damage curves using 75CC will be a bit in error. This method calculates the impedance for the worse case power factor, i. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework.

Load kW, kVA, A, hp: A is the conductor area in circular mils. I think the curves are from ICEA. The maximum allowable voltage drop. An engineer from Soutwire emailed me some pages out of the Southwire cable manual that says the all PVC.

The number of current carrying conductors in a raceway, cable or buried directly.

This only applies to thermoplastic insulation. The current rating is selected from Table The short circuit capacity is calculated as: 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 I called them on the matter yesterday, but no response yet.

Number of parallel conductors: The short circuit current and clearing time for the protection device. Thank you for helping keep Eng-Tips Ocea free from inappropriate posts. If you really plan on running the cable to 90C, your damage temperature is closer to your running temperature, and you are more likely to damage the cable during a fault.

This indicates a downside to using 90C cable. Are you an Engineering professional? Defense manufacturing is all about project manufacturing and p-332-382 accounting. I half-finished a sentence in my last post.
