Here is a POCC connection scenario I would like to bounce off others here...
A dwelling has a 200amp service with a main breaker panel that has a feed thru connection to a downstream panel that is also rated at 200 amps. There are 4/0 alluminum SER conductors going to the downstream panel.
Now we connect the solar PV source to a 40amp breaker at the main panel per code. (200amp x 120% = 240)
Is there concern that the feeder conductors going to the downstream panel are now undersized?
