power cord directionality


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

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.

I was kind of hoping you could tell me. Just a gut feeling? Oh, well, that’s the way it goes sometimes. 🙄 By the way Poynting angles are not (rpt not) incompatible with the idea of vibration distorting the signal in cables and wires. Besides, if the signal didn’t travel in the conductor it would matter what metal or purity was employed for the conductor.
