You're right, I conflated the 2 from memory. I meant fuse when I said shunt.
The outbound feed from the battery IS fused, at the main bus fuse blocks. See below though regarding the ability of the alternator to dump out more than 60amps.
But OP's concern seems to be more of the wire chafing or contacting somewhere along it's path between the battery and the main bus fuses. Someone mentioned proper wire path considerations, and wire protection; that's pretty much the only thing you can do there, besides as you mention placing a fuse right at the battery + terminal, which I don't think is done regularly, so the possibility and risk of that seems pretty low, assuming proper wire routing and securement.
I don't think this is true, I was under the impression that a bad alternator could dump out way more than 60 amps (even momentarily), and was fuse (ANL) protected for that reason.
I have attached the diagram I went by (simplified somewhat for this conversation), showing the ANL fuse right after the alternator (thank you Aerotronics!). I assumed it was to protect everything downstream from the alternator.
I'll admit, I am no electrician, I just know the it hurts when you touch the wrong wires (your fingers or your wallet
), so please correct anything written here.
