power cord directionality


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

Sorry, I thought the topic on this thread was related to "power cords"

not to be confused with "signal"

In a perfect world you should never hear power or its side effects.

You want the signal to be clean.

One can’t help wondering how does vibration affect the power cord? Assuming it does, obviously. Or, if you have an argument that vibration doesn’t affect the signal be my guest. Share, share!
Shirley you jest, mc. It’s the same for any cable or fuse or any wire. External vibration distorts the signal. Just like shaking a magnet 🧲 distorts the magnetic field lines. That’s why it’s always best to damp the wall outlet and suspend the power cord.
