I have a question about what I have been calling a "hot bus" Main Service Panel. Utility feed goes straight to the bus bars and you have less than 6 breakers feeding off of the bus. An example panel is rated at 125A and my understanding is that because the existing load breakers are: 100A, 60A & 40A, the panel is already overloaded and must be replaced if we want to do a load side PV connection. However, I have been told by others that you could, in fact connect up to 125A of solar to the open breaker slot and call it a day because the 120% rule does not need to be considered in these type of panels. We are using NEC 2017.
Can someone tell me which is correct? Thank you
