Keep in mind the 4/0 (0000) size cables is 0.46 inch diameter. This is hugh and very heavy and very hard to bend and dress up...
2/0 (00) cable size is 0.36 inches in diameter
2AWG size cable is 0.25 inches in diameter...
4AWG size cable is 0.20 inches in diameter...
I am bringing this up as alot of folks may get the 4/0 and 2/0 sizes mixed up with the smaller 4AWG/2AWG sizes that most of us use for our battery system setups... Big differences between the two sizes of cable
I have the 4AWG and 2AWG size cables and use the BLUE SEA High AMP FUSE ASSYs that look like this... This works out great for me looking for 150AMPS or so 12VDC current cable protection fuses.

I suspect the 4/0 (0000) size cables would require an even larger FUSE BLOCK assy...
