Unconnected Drain Wires ?

Thanks John.

Cpk,
Are you a cable manufacture? Name and web site please....
Jim

Dopogue, I agree with you... It means the shield of the cable is floating, not the safety equipment grounding conductor.

Shunyata's Diamondback shielded power cable and Venom shielded power cable both have their drain wires lifted at both ends of the cable.

Because Shunyata power cables are UL/CSA Listed cables Shunyata is required by UL to have a label on the cables that tells the consumer the drain wire is not connected to either end of the cable. Again it has nothing to do with the safety equipment grounding conductor of the cable.

By the way a shield on a power cable does not have to be grounded to reject RFI/EMI.

.............. but it is not a good idea as the now floating shield will act like an antenna.If you are using a shield design always connect the drain at the wall side only.

Cpk, I use to think the same way.... But how do yo explain the two Shunyata power cables I spoke of in my above post?

In general connecting the drain to the wall will give you the best sound on a shielded cord in the vast majority of system.

Cpk, thanks for your response.
As I said in an earlier post my understanding of connecting the shield to the source end of the power cable is to bleed off RFI to earth ground and stop the shield from acting like an antenna.

Then I ran across the Diamondback shielded power cable. I borrowed one from a dealer in my area and tried it on my CDP. Not a bad power cable for the price.

At any rate the drain wire is not connected at either end of the cable. And as far as I know no one has complained about RFI problems.

And here is some food for thought.... How about audio systems out there with shielded power cables that have a ground cheater/s connected to them because of a ground loop hum problem? Or systems connected to an old two wire house electrical branch circuit without an equipment safety ground.
Though in the case where an equipment safety ground is not being used there would still be a conductivity path back through the equipment grounding conductor of the power cord to the equipment chassis signal ground,... but not earth ground. Wow, LOL.... What is your opinion on that one...

I am Tel Wire. I try my best to when I give opinions to not have them not conflict/inadvertently support my design decisions.

Cpk,
No problem there..... My interest was in checking out your web site and your cables.
