Fuse question.

[Banditnib]

Hello, I have a taramps 5k md 1 ohm. I’m setting up double runs of 1/0 gauge. One thing is confusing me. The amps manual states that the recommended fuse size is 250a. If I have two runs what size fuse would I put on the power wires going from second battery to amplifier? Any help would be appreciated!
 

Here’s my set up.

320 mechman alternator 

2 XS power D5100r’s

All 1/0 wiring with all power wires fused.

Lc2i for amp signal.

Each of the two lines ideally should  have a 125A fuse if the max current draw is 250A.

Awesome thank you! I had a hard time finding a straight answer.
