We have an abandoned PoCo 5000A switchgear with its full capacity available and are interconnecting both a 2000A building maximum connected load and a 1600A solar array @480v
The problem is that the 2000A connected load is fed through (2)2000A breakers with a kirk key interlock, putting us above 5000A with the sum of the OCPDs.
Can anyone explain why the code does not have any exception for this? My thought is that if there are redundant breakers they should not be counted in this equation because the load is remaining the same. We're having issues with a supply side tap because there's no room between the breaker and transformer to easily make a connection.
I know they changed this section significantly in 2014, but I think it deserves some more changes... thoughts?
