You may be behind the curve here. There is an interlock kit available
from at least two major service equipment manufacturers that
interlocks the main breaker with a two pole breaker that controls
power from the generator. The kit cost around fifty dollars.


No, I'm well aware of them. The "kit" may be $50,
which gets you some mechanical parts, but that doesn't
address the complexity of the wiring that needs to be done
and it presumes that OP has the "correct" Main breaker in place.

They are a neat idea though and a good solution to the
whole house transfer switch problem if one were building
from scratch.

The wiring isn't at all complex. A four wire cable is run to a flanged
inlet that is cut into the bottom of any surface mount 4" X 4" X 4"
Weather proof box. The black and the red go to the interlocked two pole
breaker. The white and the green go to there respective buss bars.
About a third of the homes built in the last fifteen years have
compatible main breaker panels.
