Sub panel for transfee switch?
Loki

I have 200A service but,

I want to add a whole house generator (GENERAC 17k), but my transfer switch is only 100A. 

Can I add a 200A subpanel (NEMA 3R 12-space with 200A main) on the outside of the house and then use a 100A dipole breaker to run to the transfer switch? I also plan to install a 30A dipole in the subpanel to run to an outbuilding.

I plan to change my inside load center to 100A and just have 100A service to the house circuits (backed up by generator) It’s a small house with gas appliances and heat and my garage has it’s own 100A service (seperate meter). 

Are there any concerns installing the subpanel on the outside of the house, connecting the transfer switch to the 100A breaker and using my inside load center for the generator circuits?

I would not ever place any panel that I own on the outside of a structure. If you do what you describe, you will have a nice mess. You may want to consult your local power company and ask them to come and evaluate your situation
