Hi all. I've connected my group 41 aux. battery to an ATO type fuse block with a fused 7.5' of #12 AWG wire. I anticipate maximum load at fuse block will be 40 Amps. At 13.8 VDC, even at a 5% voltage drop, online calculators suggest that the #12 wire is sufficient to handle up to 50 Amps. Would it be ok to use a 50 Amp fuse on the wire from battery to fuse block? A 40 Amp fuse be sufficient, even with all loads on. I will measure current draw of each load. Also, FWIW, an orange murret type wire connector threads nicely onto the B+ stud on this type of fuse block.
