I'm going to use 10 AWG wire for my dedicated line and my amp will be plugged into the wall receptacle instead of through my line conditioner. I've estimated the run to be about 50 feet.
My question is, can I use Romex wire, or is there a better brand of wire I should use for my dedicated line ?
Follow Ups:
10 awg can support a 20 amp circuit at 125 vac and should be plenty depending on your system. If you're experiencing noise issues then a dedicated circuit may be helpful. If not then just make sure your system is the only user, ie: unplug or move anything else to another circuit.
I just moved to Tucson, so I'm not familiar yet with electrical codes.
I have vaulted ceiling's and I know the access in the attic is really tight to fish wire.
Just bought a receptacle from Cabledyne to use for my dedicated line.
I might just order one more receptacle from them so I can plug all of my separates into each outlet. I want to do this right the first time.
Can't be too much fun for an electrician to crawl around in an attic with not much room to move!
"I might just order one more receptacle from them so I can plug all of my separates into each outlet."
It would cost not much more to run two circuits as one. You might consider one for your amplifier and another for all other inputs. It also gives more flexibility. Plug your amp directly into the outlet, Preamp and everything else into a power strip or conditioner as you chose.
I do have the brick wall surge protector.
That was my thought too, plug the amp directly into the outlet and the preamp and separates into the surge protector.
If I choose to installl two wall outlets, would each outlet be a separate dedicated line or combine the two into the same circuit?
Two circuits, two lines make both 20 amp .
The electricity coming in is typically 240 volts with each 'leg' (of two) being 120 volts.
Both legs should be on the the same leg so connecting (cross connected) stereo stuff to both does not make any 240v potential possible.
Good point.
I guess my question was do I really need a second outlet.? My original thought was to have one dedicated line and plug my amp into one receptacle, and in the other receptacle the surge protector with my pre-amp, CD player, and tuner plugged into the receptacles of the surge protector.
But perhaps a second dedicated line might offer a "cleaner" sound for the whole system.
IMO the main reason for a separate line for the amp is so it can suck all the power it may need without stealing any from the other equipment.
That makes sense.
I'll put in two 20 amp breakers
Nothing more depressing than ripping whatever out due to code violations.
(if it is going through a wall)
I myself in my experiment quite awhile back led me to prefer stranded to solid in the ac situation. Big fat stranded wire, the bigger the better all the way up to 4 AWG in my testing on an amp. Others of course will disagree. Since this is a moderately big and permanent project you might want to put together a power cord for an amp with like 10 awg stranded and solid from the hardware store to see if you prefer one over the other. Not to say the audiophile grade solid wouldn't sound good or better. Never heard it. Looks like Romex goes all the way up to 4 AWG. "Nothing Succeeds Like Excess" according to Oscar Wilde. I will admit, 4 might be pushing it a little. But 8? T456

Also has cryoed 10-2 Romex...........less than VH Audio
https://www.takefiveaudio.com/products/1630-romex-10-2-deep-cryo-treated
10-2 Cryogenically Treated Romex (10 AWG) is fantastic for dedicated lines and is UL approved for in-wall AC power use. Deep Cryogenic treatment. by American Cryogenics, using a proprietary process developed in conjunction with VH Audio...
This is what I use... Great sounding and well worth the price IMHO...
IMHO you should stick with your 10AWG idea for better sound. Zero doubt about it, once again, IMHO. T456 EDIT: Since you have this opportunity you might even consider 8 AWG Romex. You only live once,IMHO although there are people out there that would even argue with me on that point. EDIT: Guess what I just found exists, Yep. 6 AWG Romex. Just sayin'

#10 is the maximum you can terminate to a standard receptacle. If you were to use #8 you would need to terminate a short pigtail. For #6 that means a split bolt termination and that won't legally fit in a standard box.Forget this audiophile FUD! You need to observe local and national electrical building codes for permanent wiring. It's the law. Sure you can ignore it but there better not be a fire or other property damage because of it.
If under 50 feet #12 is fine. It it makes you sleep better run #10. But that's the limit IMPO!

There is no need to think the idea of 8 AWG or 6 AWG in-wall AC wiring is an audiophile notion, since it isn't one.
The poster you responded to tends to believe that unnecessarily massive conductors sound better vs. that of a more conventional audiophile consensus.
Too bad Romex doesn't come in 00. The main thing in this situation IMO is that the OP should use 10 AWG instead of 12 AWG, a no brainer.

Too bad Romex doesn't come in 00.
Which is quite likely because there's no application for Romex in 00.
8 and 6 AWG is a lot harder to rout than 10 or higher. A lot depends on where the wire has to go. When we did my 20 amp dedicated lines, 12 AWG was hard enough! I don't think we could have worked with a larger (lower gauge) romex.

Use Romex and there is no need to oversize the wire, 12 AWG works fine for a 20 amp circut. 10AWG makes it difficult to get a good connection at the outlet because of size and stiffness. Romex (solid) or stranded 12AWG THHN run in conduit is acceptable by code I believe (I'm sure I'll be corrected if wrong). In case you were wondering All new electrical wire is made 99.9% copper. The other 16 nines you see after the decimal is mostly gimmick.
