Fusable Link Question

This one is probably pretty easy for some of the guys out there, but here goes: When using a fusable link, is it ok to use the fusable link for the entire wire or does it always just get spliced into the wire it is protecting?? In other words, for a 5" wire - can I simply use a 5" piece of fusable link wire - or - do I use say 4" of wire and 1" of fusable link?

Re: Fusable Link Question

For a 5" wire directly from the power source to the device use of just fusable wire would be fine as long as it's not wrapped and bundled with other wires.
For feed to other devices where the wire length is over 6" or so it would be best to splice the fusable section into the wire at the power source end and then route the remaining wire to the protected device.

Re: Fusable Link Question

i am not sure about this but want to check
i heard that the legnth of a fusable link determines its amperage rating, so i would think the legnth would make a big difference

Re: Fusable Link Question

both the length and the guage (size) determines the amp rating. I think there are some good guidelines at madelectrical.

Re: Fusable Link Question

Fusable link is a wire designed to melt and break continuity when excessive current is applied. The insulation is designed not to catch on fire. If broken it must be replaced with fusible link wire of the same gauge size. A fusable link should be 4 gauge sizes smaller than the circuit it protects. Acording to GM "Fusible links cut longer than approximately 9 in. will not provide sufficient overload protection". GM dealers should have all differant gauge sizes of fusable link wire.
