Here is the scenario. One unit of a 4 family dwelling is fed by #2 SE aluminum from a multi-gang meter socket to a 100 amp main breaker panel (one of the < 6 service disconnects). The heating and air-conditioning equipment are fed from this panel. A 2-3 SER aluminum leaves this main panel and feeds a sub-panel within the unit for the remaining branch circuits.
In this situation it ok to protect the 2-3 SER with a 100 amp breaker? Is this scenario what 310.15(B)(7)(3) is referring to?
Thanks
