Just some quick help with wiring

[RoYALbLUE08 10+ year member]

So im planning on running a distribution block on my boat from 0 gauge in to two 4 gauge outputs.

my question is do i just fuse the power wire near the battery with a 200 amp ANL Fuse? ( one amp has two 50 watt fuses, the other has two 30 watt fuses so 160 watts from both amps)

or do i have to run 2 more inline fuses near the amps as well after the distribution block?

all help appreciated!

You don't have to. The one near the battery is necessary. The distribution block does not have to be fused but is sometimes recommended.

300A fuse by the battery is all you need.

alrighty! cool! how bout a 250 amp fuse? isnt 300 too much?

But thanks for the help!

No, fuse rating goes hand in hand with wire gauge. 0 gauge is capable of carrying over 300A of current.

250 for 0 gauge cca & 300 for 0 gauge ofc unless the wire is under or at 4 feet.

The Fuse amperages offered are max not minimum. Also yes I would and do use distro boxes with fuses in them.
