Determining current flow to install "audiophile" fuses.

Gents,
I stuck my neck into the "Red Fuse" debate recently and it found it fruitless. This fuse "direction" debate is even more absurd. Lots of educated folks propound evidence that it is BS with AC current. All smart guys know that to be the case. Others, perhaps with an expectational bias, hear it differently and good for them and the boutique fuse marketers.

The point of my post to my erudite friends hereon, from whom I have leaned plenty (you know who you are) is that engaging GK in a rational argument about electrical circuit behavior is a fool's errand, just tiltin’ at windmills. You are trying to engage in a logical, rational discussion with him and it is impossible. He is on a different wave-length in all manner of his perception of reality and clearly loves to pull everybody’s chain who is thinking about anything that makes any sort of sense. I am scornful of his often successful attempts at making thoughtful and helpful posters take their eye off the ball, which is our enjoyment of music and the gear to do with, to engage in his ridiculously inane assertions. My best advice is not to engage the fellow as it is less productive than dealing with a petulant two-year old child who is having a "bad hair" day.  The big picture is that in the audio world, GK is as insignificant as the atoms he sees floating around on the surface of conductors.  I pity him as he brings nothing but vitriol to these discussions. We are all bigger than that. Cheers lads, Whitestix

"To make sense, the maker of fuses claimed to be directional would have to have either:

1- Manufactured the wire used in his fuses (having control over the manufacturing would facilitate him keeping track of the directional properties of that wire. Do any of the audiophile fuse makers claim to manufacture the wire they use in their fuses?)"

Excellent, excellent! Did you just take some smart pills or something? Of course the fuse manufacturer would have to keep track of the wire in terms of the correct direction and ensure that the correct direction is maintained throughout the whole manufacturing process. It sounds complicated but it’s actually not and fuse manufacturers - just like cable manufacturers - have been doing just that twenty years. Hel-looo! PS the fuse manufacturers don’t actually have to manufacture the wire. All they would have to do is check for directionality when the big spool of wire arrives. Then the directionality of the wire for the rest of the entire spool is known. Of course, some fuse manufacturers might produce their own wire, who knows? But it wouldn’t matter, the methodology would be the same.

geoff the genius educating all,how nice

So there ARE (not shouting, but my 'puter doesn't offer italicization) bulk wire manufacturers (specifically the ones from whom the fuse makers claiming directionality get their wire) who offer direction-orientated wire, and indicate the "flow" direction of the wire on their spools? I don't suppose one such wire maker can be cited?

recall from HiFi Tuning data sheets wire measures differently, albeit slightly, in one direction vs the other.Thus all the fuse manufacturer has to do is to cut the first small section of wire off the spool and measure the voltage drop across the wire, both ways. Voila! And if the fuse manufacturer makes his own wire he can see how the wire comes off the final die. So he just tags the wire to keep track of the direction. It’s not rocket science. I just saved you a phone call to a fuse manufacturer. Besides, we already know all wire is directional.
