Sounds like 2 200a panels from that, not a single feed at 400a from it...... Unless they are linked in some way? Many class 320/400 resi services are like that.
From the commentary of 240.8
Section 240.8 prohibits the use of fuses or circuit breakers in parallel unless they are factory assembled in parallel and listed as a unit. Section 404.17 prohibits the use of fuses in parallel in fused switches.
It is not the intent of 240.8 to restore the use of standard fuses in parallel in disconnect switches. However, 240.8 recognizes parallel low-voltage circuit breakers or fuses and parallel high-voltage circuit breakers or fuses if they are tested and factory assembled in parallel and listed as a unit.
Either way it sounds odd that a 400A 2-gang meter socket would have 4 200a CB's.... 800A of combined protection with no diversity on a 400A meter?
Got a model and make?
