Are fusible links Safe?
A fusible link functions as a fail-safe close valve in a containment system on a gas line, which cuts the flow through the pipeline during a fire. Fusible links offer protection against fire at tank farms, airports, and petroleum plants.
Where are fusible links located?
They are placed in-line between delicate harnesses and large sources of electrical current in your car—between the battery and alternator, for example. These links must transmit high-current electricity, but also protect the rest of the electrical system from dangerous spikes that could cause a fire.
How are fusible links rated?
18 gauge fusable links are rated at 14 gauge wire or 15 amps , 16 gauge are rated at 12 gauge wire or 20 amps. The fusible link that protects the wire should then be two gauge sizes (or four numbers larger).
What should I do if I see a fusible link?
If this (or something similar happens), you should check for blown fuses in your fuse box first. If everything looks okay, pop the hood and inspect the wiring harness for melted, scorched, or broken wires. Don’t panic if you see one, as it may simply be the fusible link doing its job.
What’s the difference between a fuse and a fusible link?
Fusible links—also spelled fuseable and fusable—serve a similar purpose to a fuse. (You can read more about fuses here.) Just like a fuse, the link is designed to handle a lower current (amp) load than the rest of the system so, in the event of a short or overload, the link will be the first failure point.
Do you need crimp connector for fusible links?
Many fusible links now come with a crimp connector pre-installed, which simplifies the installation process. Remember to weather-proof your connections—cover your joints with heat shrink tubing or tightly wrap your connections with electrical tape. Need a good 101 tutorial on electrical wiring?

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.
