Out of the box it will pull current for a 60 amp circuit. I used mine the 1st night without setup and tripped our 50A breaker. Initially fooled me because the current draw was 48A. Must've tried for more later on during the night.
I saw that there is more discussion with you and
@jjrandorin but the answer isn't being spelled out specifically.
It did not "try for more" later on during the night. With that setup, you were drawing 48A constant on a 50A breaker. That will not trip instantly, but almost certainly will within an hour or two. Breakers are built with two different trip mechanisms. One is the instant one for a very high current spike overage, but then the other one is a thermal effect of longer term heating up, where it's very close to or just above the breaker's rating for a long time, and the heat buildup will cause a trip.
This is why they have that 80% constant load provision. For that 50A circuit, it's supposed to only support 40A long term, and the heat level would be appropriate there. 48A long term was too much and got too hot.
