Electrical Shock from Ethernet Cable

[Ham n' Eggs]

So I was messing around with the back of my computer and I unplugged my network cable and to my disbelief I received a mild electrical shocking sensation. It wasn't particularly strong but it is persistent as I tested it several times with my finger (not too smart).

Is this normal?

The cable is a CAT 5E FTP Cable with Metal Ends... other writing on the wire is CSA TYPE CMG FT4. Not sure why I bought this particular cable in the 1st place... perhaps because it is shielded (is it?... I don't really know). The connectors look something like the image below. I have removed the cable from service. Advice?

It means something is grounding, which is not good and I'd look outside of the electrical cable. The cable is just providing a proper ground path. That something else is improperly leaking to ground.

maybe run an extension power cord between network devices that the network cable is plugged into, so you can power both network devices off the same circuit. So you'd plug the computer into the power strip at the computer, then plug the power extension cord into that power strip and use that to power the router. See if you still get the shock when the computer and router are on the same ground.

okay thanks, I'll give that a try and see if it helps.

Yes. If the shock originated from the metal "shielding" part of the plug, you are experiencing a ground potential problem. If you have a multimeter, you can check this by taking one lead to the metal part of the plug, the other to a metal part on your computer case. It might be a simple case of induction, with the strap to the metal part broken on the other end.

How long of a cable are we talking about here, and what is it running beside?
