It is against code to automatically connect a generator and create an overload condition on the generator. That is one of the issues with putting in an ATS. Its not just the rating of the ATS but also the rating of the generator. You can't connect a generator AUTOMATICALLY with more connected load than it can support.
Appreciate the feedback. So you determined from the fact that my ats is 225 amps and my gen can only push about 52 amps that the install is against code. I think there were many assumptions made to draw that conclusion. I have isolated circuits in a sub panel. BTW by your logic any house with a 200 amp service would need a VERY large generator to not creat an overload condition. Is that not why generators have circuit breakers built in?

You're welcome.
Its not my logic, it is however code. Look up NEC 702.4 and make sure you understand the rules for adding a generator utilizing an ATS.
And yes, you are correct that you would need a large generator for handling a 200A service.
I did make make the assumption that you were doing a whole house setup based on the size of the ATS. Just want to offer the info that you can't do that and meet code with a 10kw generator.

People are stupid.
So rather than tell people they're stupid and hurt their feels code got changed to require a generator that's automatic either:
A) be as large as the maximum possible load automatically connected.
OR
B) have a transfer switch with automatic load shedding.
Only one company tried B) in residential applications and that's now a discontinued product. (thanks for the attempt APC.)
As a guy at work was told, the larger generator is cheaper than the load shedding system.

No worries. Thanks for the update. Looking forward to seeing the install.
