Sub panel installed in unattached outbuilding. Over 2 circuit installation requires a min 60A disconnect rating. Does this mean that the feeder has to be min 60A too? I would like to install 3 20A circuits with a 40A main breaker using #8 THWN wire as the feeder. Also would like to clear up weather a main breaker is required.
