Power Cable?
« on: 11 Jul 2020, 12:27 pm »
Thought I posted this previously, but do not see where it hit the board.

I will be quick.  Can a power cable be directional?  I followed a You Tube video to assemble since both ends must ground and drain wire be connected.

Thanks -

Power cables don't have a drain wire!
US style 120V cables have a Hot, Neutral and Safety Ground  (aka Protective Earth) wire.
There is only one correct way to wire each connector.

Stop wasting your time watching any U-tubes from those people.

The Supra power cord line has a drain wire that must be connected to ground at both ends.

The two reasons for directional cable are attaching the shield at only one end, which makes sense but doesn't apply here.  The other reason is that the wire within the cable becomes directional as you use it, which again doesn't apply here as you can't switch ends on PCs.   So I wouldn't worry about it at all unless the cable itself has a directional arrow imprinted on it, in that case why not, what could it hurt?

They do have a directional arrow but it will not matter.  Actually surprised the brand touts the LoRad SPC version for hospital and military use and still has the direction on the sleeve.

And these are already assembled with sleeves and heat shrink.

Thanks for responding -
