  1. NEMA 14-50 Supply cable heat data

    daveo4EV, well said and agree with all. Also, your other ways to measure power are confirmation. I won’t think the Porsche readings are wrong, but you never know. It’s their first version.
  2. NEMA 14-50 Supply cable heat data

    I am totally with you. That’s not right. It’s very interesting why we are having different experiences with similar setups. Do you have the ability to put an amp meter on wires connected to the breaker to see how many amps you are actually pulling? Could the charger be misrepresenting the amp...
  3. NEMA 14-50 Supply cable heat data

    I think I agree with this. Given the shortness of the cable, I think it can probably handle the 40A. It will get warm, which shouldn’t be a problem. Will be interesting what Porsche says. I have 6/3 wire in MC running 90 ft, 14-50R running and run at 40A all day long. The wire is cool to...
  4. NEMA 14-50 Supply cable heat data

    I looked up the specs on the wire and came across whip ratings from the manufacture of my cable. http://www.yung-li.com.tw/EN/Products/heavyduty_nema.htm The 4-50P whip with 10 AWG wire is rated to 30A 125V/250V. Not sure this exactly the same cable used but is probably close. Maybe the short...
  5. NEMA 14-50 Supply cable heat data

    Would you mind providing where you got this. I think that might be the rating of the insulation on the wire (90C/194F). Different wire insulation is rated to different temperatures (60/75/90C) and that does not mean it will be that temperature at max amps.
  6. NEMA 14-50 Supply cable heat data

    I am not an electrical and it might be good to get an electrical engineer to comment. Not all 10AWG cables are made the same and have different properties. Solid, stranded, insulation, conduit types make a big difference on the amount of amps vs heat generated.
  7. Do you use the power button or the park button & lock when you leave

    My dealer recommend that I just put the vehicle in park, get out and lock the doors. That seems to have some advantages as the climate control stays working and the handles pop out as I approach. But, the comfort access seat/steering wheel movement does not happen. Pressing the power button to...
  8. Help... which of these options to get?

    Depending on your climate. We have hot/humid summers and cold winters. Because of my location, I would option the heat/cooled seats. I would really miss the heated seats.
  9. Electrify America Poll

    I have used only one of the charger stations in my area before I got my home charger setup. Of the 4 times I charged, from 20-80%, I never had a problem with the charger. I did have a problem with the Connect app on my iPhone a couple times. Completely closing out the app and reopening fixed it...
  10. Recuperation Button

    I use it around town as well. Mostly to help slow the vehicle down quicker because I keep hammering the accelerator. I really like that it's on the steering wheel.
  11. NEMA 14-50 Supply cable heat data

    I just install my dedicated 50A circuit. I used 6/3 wire (with a proper ground) MC wire with a total distance of about 90 ft. I used MC wire over NM because it can carry more current without heating due to the lack of dual insulation. Have been charging at 40A for about 2 hours and check the...
