I am looking at installing a generator interlock in my interior sub panel but had a few questions before I purchase any material. I have looked at the Reliance generator transfer switches, but would rather use a generator interlock to reduce complexity and increase flexibility.
Current setup.
1. Exterior weather proof main with a single 200 amp main.
2. Interior garage sub panel with no main.
Questions.
1. For a generator interlock, I need to have a main and generator breaker in the same panel. My SqD exterior main panel does not have provisions to install a generator interlock (Q22200NRB) that I am aware of, and I certainly don't want the expense of replacing it with one that might.
Thus I need to install a main in the sub panel. Is this allowed per code? Obviously I will have to move loads to install a generator breaker in the 2-4 position.
UPDATE: A main in a sub panel is not required but recommended.

2. While running on a generator, will I need to make any provisions to any line conditioning or anything else to allow Insteon signals to continue to work? My sub panel has a floating neutral, but I assume in my main the neutral is grounded. What about the generator neutral? Should it be grounded to the frame of the generator or floating where is presumable is grounded via my main breaker box?
I plan on using the following generator unless someone has a better recommendation.
