Hello folks, I am looking for some clarification on article 230.79 pertaining specifically to the minimum size overcurrent device required for a dwelling unit.

View 1. Part (C) indicates a 100 amp minimum as the overcurrent device; which would require the smallest feeder to be a 1/0 AL SER.

View 2. Part (D) can be applied since this is a multifamily, and we can do as low as 60 amps; allowing the smallest SER runs to be #1, or even #2 if the unit load is small enough.

Thanks in advance

Kevin
