For what it’s worth, GM uses 5.0 mm sq. fusible links on their factory auxiliary battery option for the charging wire. Two, actually.

What kind of wire is protected by a fusible link?

For example, a 14-gauge wire would be protected by an 18-gauge fusible link; an 8-gauge wire would be protected by a 12-gauge link, etc. Odd number wire gauge sizes like 19, 15, 13, and 11 are counted when sizing a link.

What do fusible links look like in Pico?

Pico makes fusible links and is nice enough to give each one a plastic tab with the wire gauge and “fusible” written plainly to see. (Image/Summit Racing) Well, that’s the fun part. They look like wires, which can make troubleshooting a headache—we’ll get to that in a second.
