Pedestal MSP only has one 100 amp breaker no distribution, it's calling for a 60 amp backfeed breaker to come out the pedestal panel then going to an AC combiner box ,but I have no room, my question is can I tap in to the number 2 wires on the load side of the 100 amp breaker then hit a 60 amp fuse disconnect ,or would I be better off putting a 100 amp subpanel then put a 60amp breaker in the subpanel thank you
