Circuit overloaded

The way you have it set up, the transformer is pulling 1000W from the line + 10W from the light bulb for a total of 1010W and that is why it is overloading the cable. I can't see the rest of the circuit on your image, but overloading is to be expected with how you plugged the transfo. Maybe you meant to limit power on the line with the light bulb? If so, swap the transformer input/output. It doesn't seem like a bug.

yeah... from what I can see, not a bug.

batteries have no power output restrictions, and the 1000W + 10W do indeed add up to 1.01KW

if you want this to work, remove the battery and the max power you'll be able to consume on that cable (because you won't be able to produce more) is 800W

As the others have said, the cable limit is 1kw. The transformer uses 1kw. That alone maxes out the cable. You also have a 10w light bulb which pushes it over the limit and overloads it. Remove the lightbulb and it'll stop overloading.

Thanks a lot. I see, it's not a bug, but a feature and game mechanics.
So, I will take it as it is.
Can we close this issue?
