Fusing Help

[Hades2004 10+ year member]

I'm probably going to order my new wiring and all that for my new amps. The amps have 2 40A fuses on them. Thats 80A each cause i'm getting 2 of these amps. So thats 160A. I'm going to get a fused distrotion block that has 1/0 gauge input and 2 4 gauge output. This is a ANL fused distrotion block. Each output will have a 80A ANL fuse. And now for my 1/0 wiring going from the block to the battery, will a 150A ANL fuse be fine?

Fuse at the battery to protect the wire from catching on fire. I see 250 amp recommended quite a bit. Its really up to you, the point is to have the fuse blow before your wire burns. 200 should be fine, maybe even the 150.

put a 200-300A fuse on the main line and a 100-150A on the 4awg lines.
