Your home draws surprisingly little minus air conditioning, range, etc.
A breaker will work both ways even if you are back feeding the buss.
If you push 30 amps through a 20 amp protected branch circuit, it’s going to take a few minutes to trip. It gets exponentially shorter the higher the amperage is over the protection amperage. Not to mention the protection in the generator. These generators that have these nema 20 amp plugs (I forget what number it’s been a while) are protected 15 to 20 amps anyway. The breaker on the generator will trip.
What does this have anything to do with house wiring? Home power distribution is designed to protect wiring in these cases. This is nothing extraordinary it just appears so because it isn’t normal.
