How do you replace a fusible link?

The single wire is connected to two wires that have a fusible link and each of them have two different gauge wires on each side of the fusible link. Sorry if I made that confusing earlier.

I see. I still think it is acceptable. You are feeding off one large wire into two smaller ones. See if Dell chimes in. He'll let us know if I am full of **** or not. LOL
