What is everyone using for dedicated AC lines???

Check out the Virtual Dynamics site. The have cryo'd circuit breakers and inwall wiring.

I haven't tried it yet, but I will.

Eldartford, 10-3 has four conductors as Glen stated. The fourth leg usually is used for running an isolated ground. You would also need to have a receptacle capable of using that feature though, like a PS Audio Power Port. My electrician shook his head and declared it overkill. I told him many would think much of my system is overkill.

I just upgraded my ded. AC system using all Virtual Dynamics cryo treated wire, breakers, and Hubbell 5362 outlets. 10/4 BX from Main panel to sub-panel $3./ft. (actually 10/3 w/ ground), and then 10/3 (10/2 w/gnd) from sub panel to outlets. 30 amp cryo'ed breaker in main panel, and four 20 amp breakers in sub-panel. All this is now broken in and sounding excellent-- sweet, mellow, live, and most of all very, very natural. At $3./ft. for the wire, I did not consider it excessive. This has been a very worthwhile upgrade. Good Luck. Craig

I used 10/2 romex. I would be cautious, check with your insurance company, about using something that does not meet or exceed your building codes. If it causes a fire you could be liable.

Jmcgrogan2....The uninsulated ground wire goes without saying in X/2 or X/3. With either voltage you need only power wires (plus ground). With 110 it's 110 and neutral (which is nominally ground). With 220 it's +110 and -110 so that you have 220, line-to-line (plus ground).
