I got a sweet deal on some nice Belden 14/3 shielded power cable so ive decided to make some cables to replace the stock cords in my system. I have a question though, the cable has a drain wire, where should I connect this?? Should it be connected to ground on one end??? If so which end??

If this is what you have, it makes excellent power cords. Do a search over in the Cable Asylum for the Asylum Power Cord, credited to the late Bob Crump. The drain wire is attached to ground at the AC plug end. Good luck, DaveBTW, finished cords using Belden 19364 and decent IEC/AC connectors are available very inexpensively from RAM Electronics (note: their website takes forever to load) and other sources.
Heya Frank25,My understanding is that the drain wire is typically connected to the ground plug on the side nearest the electrical outlet. It should not be connected to the ground on the side nearest the unit. See the link provided, and look at the diagram for "Flavor 1".
Just a thought IMHO....Many people don't like to use shielded power cables for their amplifiers....many shielded cables seem to restrict dynamics....but what works well for you, may not work for others...
Best of luck, and be safe.

Also, check the archives....there are quite a few questions and responses to this very same question....
I'm no expert, but I have had success with several common DIY PC designs now.Conventional wisdom for analog components is no shield. This is NOT always the case, however.
YOu can look up the power cords on TNT-audio.com and you'll see at least one that is braided out of 3 wires of shielded 2 or 3 wire cables. They claim it works very well, though it's not the typical design you'd see here on AA. My experience with TNT is that they often come up with workable and reliable designs; they're not flaky. I've seen similar designs for sale on Audiogon, so they're not alone in this different shielded PC design.
For the usual Belden shielded PC design (often relegated to the digital components) what you're describing is what I think is called a floating shield connected at the source end of the power ONLY. And that should work well in the right places.
I don't recall Frank saying which Belden 14/3 cable model he has. That, too, makes a difference.
Some guys here claim that the terminations are even more important than the geometry or the AWG. So he shouldn't skimp on those. But once he's made the cable and seen what it can do, if he's still intrigued he can upgrade the terminations later; not a big deal if you don't solder them.
