Hi,
I have a 200A house setup. I'd like to install a manual transfer switch for a generator. I was originally going to use the Manual transfer switch as the main breaker (service disconnect) as well, which has to be installed on the outside of the house per NEC 2020. My wife does not like the look of the panel since it is large (24in tall by 15in wide). So as an alternative, I'd like to install a skinny outdoor circuit breaker panel (1 breaker 200A) on the outside of the house then feed into the garage and immediately go into a manual transfer switch (200A main breaker) then use 4/0 SER cable to the main breaker which is 100ft downstream, and also has a 200A main breaker. So essentially, I will have three 200A breakers on the same electrical system.
200A (outside main) -> 200A (inside manual transfer switch, immediately inside relative to the outside 200A breaker) -100ft cable-> 200A main panel
Does anyone see a problem with this setup? does it violate code? I don't think it does because if the system over-current happens then any of the three 200A breakers will trip it.
