For instance a 110v 15A house circuit can be 14g wire. If you bump the fuse to 20A, the wire needs to be 12g. Or perhaps the wire size is sufficient to handle the 20A and I should just shut up.
Just asking…

It's not a dumb question. If you don't know the answer, it is not a dumb question
And it could be a problem in a house - certainly an inspector would fail it and you would have to put it back.
But, like Jeffrey said, it is intermittent use in this case. The wires may get a little warmer, but the window is up/down before the insulation gets soft or melts.
In the house, you can and do have long term loads that can soften/melt the insulation and cause the house to burn down.
