I take your meaning entirely and I agree it is very easy to get it wrong -
I've done it often enough, but you've got that protection either with the
power poles or with the jack plug, why have both?
I'm even thinking you don't need the fuse. If you think you need a fuse,
use an electronic one that will drop less volts. You should ask your self:
what is the fuse protecting and where will the short occur that will pull
enough current to blow it? The usual answer is a cable short which leads to
another discussion.
