I thought they did but I wasn't sure. Glad that I just went with fuses

Thank you everybody for your inputs. It really does help. I plan on using fuses all around now. I currently only have 1 battery for the rear, an XS Power d7500. I do have a Mechman HO 275a

1/0 OFC can handle that 275 amp alternator, but 2/0 OFC would give you less voltage drop over that 17-20ft run from the alt to the battery.

I would also suggest running 2 2/0 OFC runs from battery to a distribution block, then run all amps off of that distribution block with each line fused to recommended amperage (assuming 2 350 amp fuses for the 2 power supplies on that Orion amp.)
