702.5 requires that a generator with automatic transfer equipment, is to be sized for the full load that is being transferred. if the transfer switch is service rated and located on the line side of the service disconnect the load is to be calculated to article 220 and the generator is to be sized to the load. if the transfer switch is located on the load side of the panel, example a 12 circuit transfer switch protected by a 50 amp breaker in the panel. does this type of connection require load calculations, load shedding ect?
