Just my 2 cents on the fuse. You don't *need* it, the spring does serve the same safety function, however, the fuse (I use a shortstop) after being tripped, will, within a minute, reset itself, and so is reusable over and over. The spring has to be replaced if it sags.
The link above for the shortstop is not where I got mine, the place I got it is out of stock. It's just to show you what it looks like and how it operates (sort of)
