Fusible links?

[OH71RRunner]

I'm starting to find more and more problems popping up. Fusible links are a little confusing to me. I'm not quite understanding the concept of them over a regular fuse. I think that they burn from too much heat of amp draw? I've tried reading up on it but still confused a little.
I'm going to do some wiring upgrades and trying to figure out if fuses would work better or more efficient than a fusible link. There seems to be some debate about that.
So the questions are, is it better to use fuses rather than using fusible links? Which is the most efficient to use? Ease of use is a fuse, but which is the more reliable?

Fusible were used because they were cheaper than installing a fuse and holder. I'm not sure of the amperage of the fuse but installing a holder that is visible is a lot easier for troubleshooting and replacement. Fusible links are usually 4 wire sizes smaller than the circuit wire. Search for info here.

Ya, I've seen things about the wire sizes. I'm trying to figure out if a fuse would be better or not. From what I've read (and understood) the fusible link can hold up to an initial higher current than a fuse. It seems that some electrical components draw alot of amps to start. But running a higher fuse allows more current than what would be needed and could take longer to blow. I think I'm understanding that part right, but not sure. I want to wire stuff the right way and still have the proper safeguards, such as a fuse or fusible link.
Maybe I'm overthinking some of it or getting things mixed up from what all I've read. I just want to make sure I do things right.

See this post and links from it, and this one.

There's not much to them, all they are is a short piece of wire spliced in that burns in half. You can buy them in different amp ratings to replace your originals.

Don't like them and won't use them, I use a fuse block instead where the burned link is contained and not a fire hazzard.

Thanks for the info. I was overthinking it, like usual. Basically, there's some applications that a fusible link is necessary. But with slow blow fuses, they kind of behave like a fusible link and can replace it. Sometimes a regular fuse can replace a fusible link.
It really boils down to the application, or component being protected, to determine what style of circuit protection is needed.
I've never gotten this in-depth with wiring before and wanting to avoid headaches and a meltdown or fire. Lol
Thanks again for the help.
