What in the world are you guys talking about or worried about? If you get a 30 or 75 amp unit, it doesn't matter if the fuses are 30, 35 or 40 amps on any of them. A pair of 30s on all of them would be fine I would think. These are reverse polarity fuses AFAIK and enough to protect the unit if we accidentally cross the battery leads. Check their amp output if you have the ability. Mine cranks out 3% more than rated when my batteries are low, except our PD didn't after 15 mins. FWIW, my Iota did too. We have a fleet of RVs so luckily can test several of them. I like the Boondocker and waiting for the adjustable one to arrive.
On my 100amper it appears the four 40s are all on the positive output wire so the 160a of fuses carries the full current. AFAIK with any brand it is the same idea and you see more amps of reverse polarity fusing as converter rating in amps goes up.
We had a thread about this a long time back and can't remember how it all works. Something about the two 30s making a 60. I don't know why they split it up into several fuses. Perhaps because it is easy to buy those 40s and 30s if they blow.
Yes the converters seem able to do a little more than rating if you get them close to the batts on short fat wire. I can get 56a on my 7355, I got 61a on my old Paramode 55 (RIP), I can get 104a with my 100 amp PowerMax.
I do like my PowerMax too :)
------------------
OP, yes the shipping thing is a turn -off. When my Paramode converter quit working, the warranty drill was for me to ship it to them ($50 approx at the time) and IF they agreed it was a warranty item, then they would fix it and pay up after.
I had monkeyed with it by using its internal pot (like the one in the PowerMax) so I figured they would deny my claim just for that, and didn't send it in.
Perhaps you could show them some photos of the unit with the lid off and one of the lid's label showing the 75 etc and the end with the fuses to convince them it is peculiar instead of having to send it. No idea. They are good guys if you don't annoy them, same as anybody. :)
