12:20. The way I'm interpreting the ex. regarding existing installations, if you needed to replace a breaker on a pre-1980 split bus panel, you're allowed to do so provided the total number of breakers on the upper bus (main section) doesn't exceed six. Is that correct?

So who makes a 400A meter main that complies with 2020 NEC 230.71? Can you list a few models? I have a 400amp main panel in my garage/workshop with pass thru lugs to a 200amp panel in my house with pass thru lugs to a 100amp smart panel in my basement. I live off grid in a remote area and run my entire site using PV Solar Energy and would like to add EMS to manage my entire site.
So who makes a 320A meter main that complies with 2020 NEC 230.71? Can you list a few models? Every model I find with two 200A breakers has both breakers in the same compartment. One example is Siemens MM0404B1400RLM.
