I have a project where I am trying to install equipment for distribution service to two different buildings in a substation facility.

The distribution service from a normal and alternate source will be fed via ATS (located on the inner wall of first kysor building- Control Center#2) to two 225A panels via 225A breakers. The service cable from ATS will also be fed to the second building (Control Center #1)150A breaker via a 225A breaker located isnde CC#2.

Please refer to the attached drawing. (service side of ATS not shown)

My question for you all is, do you see any code violation?

Does it comply with NEC 230.3? If not, what is the reasoning behind complying with NEC 230.3?

Also, most importantly are you aware of any breaker panel, which would carry all three 225A breakers within one assembly (items inside dashed line) and has a small form factor to be mounted inside control center 2?

I will appreciate your advice.

eric,
I am still struggling to understand your response.
Let me make sure that you are perfectly clear on the fact that CC1 circuit initiates at Control Center #2 travels about a 1000ft and then connects to 150A breaker in Control Center#1

Now, Let me rephrase what I think you are suggesting from your last post in the form of two options. Could you please pick one which you are suggesting?

1- Have no protection for the feeder at CC#2 feeding 150A breaker, which is located at CC#1

2- Have 150A breaker placed in CC#2 and no breaker in CC#1

I have a problem with both, but that's another issue. I want to make sure that I understand your suggestion clearly.
