Glad you are back up but the 12VDC fuse are on the 12V side of things... Should not have bothered anything on the 120VAC side of your power distribution panel...
Fuses just don't blow for no reason too haha...

40 AMP fuse is most likely the reverse polarity fuse. In our Hybrid Travel Trailer, we had a blown reverse polarity 40 amp fuse once while out camping. With that fuse blown, the converter/charger would not charge the battery.
With that camper, any time we removed & replaced the battery, the 40 amp fuse would blow. We never reversed polarity, but it would blow every time. Eventually we removed the fuse before removing the battery. That saved us from buying 40 amp fuses.
