I was planning on a 250A blue sea fuse and 75mm2 cable. I suppose I could update the blue sea fuse to 300A (and cable if needed) then use the 250A mega fuse to the inverter, leaving 100A for my other loads.Does depends what capacity your Blue Sea fuse is, whether direct or via the mega/maxi fuse board as either way there's a chance you're going to be pulling 200A through the Blue Sea fuse for the inverter with any other 12V loads running from the remaining 50A capacity so it would be possible to blow the two big fuses in cascade.
In the real world I've never blown anything larger than 80A fuses but they were the glass tube type, ok for car audio back in the day but not modern manly loads!![]()
I was thinking of swapping the power to my amp from the starter battery to the leisure. That’s 2x25A fuses, so I might not bother. Need to have a think about which way is best.
