I can't believe you wrote that.

So what exactly is so different about leads chafing and shorting and
leads being clipped together?



The surmise is that 'when connected to the battery' and the leads short
together you get battery power through the leads.

However, in practice, the leads will just become a fuse and burn out.

There is a remote chance of this causing a fire, so if you think it is
likely to occur then add a fuse near either or both of the crocodile clips.

And doing so for most would just introduce another likely source of
problems. An inline fuse carrier isn't designed to be bashed around as is
likely to happen to such leads. You'd need to design a new crock clip with
a proper built in fuse.

But why would you? These things are already fool proof. Idiot proof, even.
Making them cnut proof will be costly.
