I need help in your interpretation. I have a multi occupancy building, single story with suite 200, suite 300 and suite 100 in which one service from underground electric utility comes into Panel A in electrical room inside building. The Panel A does not have any meter, disconnect to individual suites instead all the circuit breaker go from Panel A to suite 200 receptacle and light and suite 300 receptacle and light. Their is subpanel fed from Panel A which in electrical room which feeds mechanical equipment and then some Suite 300 loads. Their is transformer XFMR-B fed from Panel A and secondary of the transformer feeds Panel L2 all in electrical room which then feeds Suite 100, 200 and 300 loads. I am very confused as to which NEC section does this violate and can be enforced NEC 225.35, 230.72(C), 240.24(B) or some other NEC Article?
