I trust the chart because of the source...but my own experience differs - if I'm reading that right, it's saying that it would take 20 seconds upto a max of 400

I trust the chart because of the source...but my own experience differs - if I'm reading that right, it's saying that it would take 20 seconds upto a max of 400s at 2.5 times rated current: that's 50 amps up six minutes? I have a hard time believing that. Pump 20a though any breaker you find it trips nearly immediately
