I saw your fuse box here and I am looking for a panel for12v bus a/c systems. It needs to have space for 4 or 5 relays and 10 fuses. 1 fuse is 5 amp, 2 fuse/relay positions are 20 amp, 2 fuse/relay positions are 15 amp and if possible 1 is 40 amp. If the 40 amp is too much power that is ok, we can wire that seperate. Without the 40 amp fuse, our systems uses around 40 amps maximum.
