    Is There a Ratio Between Short Term and Continuous Current for Power Cables?

    ~40 mm^2 cross section mostly because the current decays so fast after 1 time constant, so this makes sense.

    Is There a Ratio Between Short Term and Continuous Current for Power Cables?

    I redid calculations with real RMS values and the cable size is much much smaller! thanks for the help!

    Is There a Ratio Between Short Term and Continuous Current for Power Cables?

    Okay, I think I'm going to listen to you for simplicity reasons. With the 95 mm^2 results, then a size of 4/0 AWG copper cable should be sufficient. Can you show me where you got the equation and k values from, I need it for a presentation. Thank you for your help. Actually, the purpose of...

    Is There a Ratio Between Short Term and Continuous Current for Power Cables?

    Hi guys, I'm looking to find out if there is a ratio between short term and continuous current for power cables. I know that people usually generalize around 5-10 x rated ampacity, but I'm just asking around to see if there is a certain #. On McMaster Carr, the highest rated cable is for...
