Any suggestions on wiring for a 20 amp dedicated line. Romax? 10'gauge?
Thanks

I have been following your posts for some time now, BenE.
You must be putting together quite a system...
Doesn't code call for 12?
For what is a wacky short run, that's exactly what I'd use.
Too much is never enough
Well, I was insane, and have 4 dedicated lines here (3 for the main rig, one for the HT). All 20amp. Bought a house, that had some older systems I upgraded over time. Started with the Stereo, I ran 12g on 2 ded lines, and 10g on 2... solid core and stranded... broke it all in, for over a month plus, all using same Acme outlets.
10g solid core won by a long shot, if sound matters. The 12g is light weight in sound, and in dynamics, and much smaller in size of stage... 12g stranded being the worst of the bunch, just a more 2d presentation. It is similar to when I had a Furman 20amp balanced power conditioner and AudioPrism Foundation 3, and not, in a previous locale, where I could not have dedicated lines. But larger; in that the difference between the 12g stranded and 10g solid. laugh out loud stuff. The sound of the 10g solid, was so much better than the others - I had to switch the other 4 out (and used them for non-audio runs like to the kitchen, garage, and washer/dryer... where they meet code, and allow for length/voltage drop if a longer run circuit).
10g solid core is a bear to work with, but once broken in, is so worth it.
remember that wire gauge are reverse numbered - 12 is smaller than 10...
For this short of a run 12 would be fine - but for 10' - go for the 10...
Absolutely. NO need whatsoever for 10ga. in a 20 amp circuit of such a monumentally SHORT run.
Like a guy that runs 'V' rated tires on an old 36hp BEETLE.
Too much is never enough
I'm using Chris VH's cyroed 10ga Romex. 10ga is a mofo to work with. Just take yer time with it and you will be rewarded.
With #10 wire (solid or stranded) max distance before voltage drop would be 57 feet-
If the distance is greater - look at #8, for 90 feet of distance.
The damage is Voltage drop at or near load - which can be significant if not accounted for-
In a work situation I had an Ultra Low (-80C) Freezer that would not operate on a 10 amp (208VAC) circuit w/ #10 at ~200 feet...
@6bq5 or anyone who can answer. How does voltage drop affect performance of equipment...ie...in this case, stereo system.
Thanks in advance.
as the wire size changes, smaller, the resistance increases as a factor of length,
Thus a long run of 12 gauge will NOT be able to deliver the full voltage at the terminus of the line - so 120VAC at the breaker end of the line could, depending upon length, drop to 105 VAC, then the supply into the transformer will be low, and as transforms are ratio based, the output from the transformer with low input will be affected. Which will affect the balance of the equipment- sagging B+, means lower bias for gain devices, timing circuits based on capacitor charging may not trip - if they do not get to a high enough voltage, some SS regulators will have reduced or no output
So in short the equipment will actually suffer as opposed to benefit from the dedicated line.
@6bq5...Thanks!
It's a short distance 10 feet or so. First floor to basement with panel directly below.
I can't compare to other wires, but I'm using 10 ga. solid core Romex, which is really hard to work with. But sounds great.
Thanks. Good to know.
Cryo'd 10 AWG Romex is a popular option.
Hi Duster,
10 is very tough to snake through walls. When I did 12ga, it wasn't easy. He should consider where it is going also.

Thanks. Where is a good place to get it cryo'd?
VH Audio sells cryo'd 10 AWG Romex.
See link:
Alan's been selling this for years.

I will check it out. Thank you for the information.
