What size fusible link do I need?
A 14-gauge wire would be protected by an 18-gauge fusible link. A 6-gauge wire would be protected by a 10-gauge link, and so on. Odd number wire gauge sizes like 19, 15, 13 and 11 are counted when sizing a link. The length of a fusible link should not exceed 9″.
Why does my fusible link keep blowing?
Circuit Overloading The easiest way to blow a fusible link is to pass more current through it than it can handle. Doing this will open the floodgates for electricity, and the fusible link will blow out like a drinking straw on the end of a fire hose.
Is a fusible link just wire?
An electrical fusible link is a type of electrical fuse that is constructed simply with a short piece of wire typically four American wire gauge (AWG) sizes smaller than the wire that is being protected. Electrical fusible links are common in high-current automotive applications.
What is the difference between a fuse and a fusible link?
Again, a fusible link’s function is very similar to a fuse. It’s designed to fail before your wiring harness melts to goo. As a general rule, a fusible link is made of wire that is four gauges higher (smaller) than the rest of the circuit, making it the weakest link in your electrical chain.
What is the purpose of a fusible link?
A fusible link is a mechanical or electrical safety device. They are used in fire sprinkler heads to activate the sprinkler in the presence of heat. They are used in automobile electrical systems as a fuse.
Can a fusible link be repaired?
Fusible links can be frustrating to diagnose and repair, because their damage can be impossible to detect with a simple visual inspection. Once you locate it, you can replace the length of wire with a fusible link that matches the gauge of wire called for by the original design.
How big of a fusible link do I Need?
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. The length of a fusible link should not exceed 9″.
How big of a fusible wire do I need for a 6 gauge fuse?
A 6-gauge wire would be protected by a 10-gauge link, and so on. Odd number wire gauge sizes like 19, 15, 13 and 11 are counted when sizing a link. The length of a fusible link should not exceed 9″. Can a fusible link be used to replace a fuse that blows frequently?
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.
Why are fusible links used in automotive applications?
Fusible links were used in automotive applications so the manufacturer could get away with using lower-cost, thinner wires. Fuses blow quickly when the current passing through it reaches its rating. Fusible links take longer to overheat and can withstand temporary excess current for longer periods than fuses.
