I don’t think that wire can handle 80A. So it is still kind of a fuse.
Just in case anyone takes this the wrong way, part of the purpose of over current protection is to keep wires from melting, so if your protection and the thing you’re trying to protect both melt at the same time, your protection isn’t really working.
But if this wire melts before the other wires melt, then it kinda works to some extent
The wire fuse
Isn’t that rating when the wire insulation catches fire and not when it melts? Copper can stand a much higher temperature that anything surrounding it, so the wire might survive long enough to cause the thicker wires to catch fire.
Anything is a fuse if you pump enough angry electrons through it.
All machines are smoke machines if you operate them wrong enough
Eh, if there is a problem it will melt.
Oh the irony of using a green wire
Its completely “grounded” to use green…
Apologies for ignorance, but what am I looking at here?
green wire bypasses a fuse, completely mitigates the protection a fuse gives
This made me realize I have no idea what fuses are.
In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current. It is a sacrificial device; once a fuse has operated it is an open circuit, and must be replaced or rewired, depending on its type.
And Circuit Breakers serve a similar function with a different mechanic and are resettable. Any modern house ought to have many of these inplace on the main electrical panel.
So it makes sense that we call it a “fuse box.” Thank you!!! I got a little smarter today!
Interesting, thanks
