power cord directionality


IF power cords do indeed have preferred directionality, and one is inadvertently flipped for a few hours, does it "harm"it?

Now back to the debate about whether copper or silver is better for passing an audio signal!
If wire has "directionality" why hasn't somebody in the past two hundred years found a way to measure and quantify it? Instead all that can be said is "my golden ears tell me it is so". This is NOT a scientific method in the least!
You DO realize that, unless you’re running off batteries, it’s “Alternating Current” right?  So how in heck can power cords be “directional”!!!
Is the preamp working properly? Does it sound fine? If so, don't worry about it. The wire doesn't care. Most commentators didn't know it was a wire between an outboard power supply and the preamp. So it IS supplying DC. All power cords going into the wall sockets, all interconnects and speaker wires are carrying AC and the current is reversing at many frequencies all the time. Unless someone is playing tricks with sheilding (some only ground one end in special situations) the directionality of wire is a myth.
I wonder if all the wiring installed in your house by the building electrician has been installed directionally correct? 😷🇦🇺
uhhh...  duh end wif duh prongs on it gits plugt innuh wol.  duh uther end innuh yer lektronix.  

how yu gonna ree vurs it?
Well, you would know if it was really done if the arrow is now pointing in the correct direction.
Why not call the manufacturer, explain your situation and see what he advises.
....thx for the straight answer!  Part two, should I have it fixed, as who trust knows if it was labeled wrong, is truly backwards, and if I send it back, how will I know what was really done?  Facepalm.....

Power cords and fuses and any cables, even digital cables and HDMI cables, are directional in DC and AC circuits. Everybody is on board the DC train. It’s the AC train 🚂 that gives audiophiles a case of the 🍑 It’s because of the inherent directionality of wire. 🔜
Perhaps I was less than clear. This is umbilical cord btwn power supply and preamp. Carries DC I’m pretty sure. Neutrik
male and female ends. Was assembled backwards

Would not this equal to forcefully switch it's "gender"?

Was wondering...what will be this aft chuckle...
Did not have to wait long...
It’s the same as for fuses. Power cords are directional in AC circuits. Come on, guys.
Like people who have been brainwashed, it needs to be deprogrammed, left to rest, and then reprogrammed.
I guess it’s safe to assume fancy cable makers like Synergistic Research and many others are adhering to pre-determined directionality of the wires.
So a PC should be terminated with regards to wire directionality predetermined.
No harm per se but umbilical cord with male - female connectors can only be plugged in one direction. Now my mono amps with external power supply came with umbilical cords with same male speakon connectors on both ends, like the one below with no directionality marked on the wire.

So when I asked the manufacturer, he said it should not make any difference which way I plug the cords. I heard no audible differences when I reversed the cord in other direction.

I have yet to see a professionally made power cord with male AC and female IEC plugs marked with directionality.

Our resident directionality guru @geoffkait may disagree with my assessment 😊
good question....I just had an umbilical made, and the Male -female ends did not correspond to the indicated directionality.....
I did not notice the directionality indication until after using it for a short while'
How can it even be used in the "wrong" direction?  Please provide more facts.
