I am looking for a fuse holder that will hold 2 ANL fuses that has one 1/0 in and one 1/0 out.

Do they exist? or am I stuck?

I am using the Stinger 3/0 oval wire to the battery bank in the back, I just dont think a single 300 amp will be enough.

Thanks

1/0 will not support that much power two runs of 1/0 each with its own 300amp fuse.

Considering the fuse is there for protection, I don't see why you would want more than 300A, only in the case you have massive current draw for sustained periods of time. 3/0 can support it, but are you drawing in excess of 300A ?

** Your wire needs to be the proper gauge/length to support certain fuse ratings... If not properly fused the wire can melt before the fuse blows

charts can be found on line for gauge requirements for any given load/length of wire.

If you have current draw in excess of 300a.. you need to be running more lines.

A pair of SAZ-3000D's and a pair of SAX-100.4's

I'm planning on 4 batteries in the rear and 1 up front, I just need the run from the front to the rear.

Its going to be a run of the 3/0AWG wire, there isn't anything that I can find that will let me use more than one ANL fuse.
