What type of wire for dedicated 20A AC lines?
I’m about to have two 20A dedicated lines installed. What type of wire should I use? I know there are differences of opinion on whether to use 10 AWG or 12 AWG, however the link below makes a great case for using even 8 AWG solid core copper on longer runs like mine will be (50 ft), to ensure a lower resistance, lower voltage drop over the long run, and therefore more access to instantaneous current for my Gryphon Diablo 300. The wire would need to be stepped down to 10 AWG to connect with the receptacle. The article actually states that the thickness of the wire is more important than the fact that it is dedicated…
Assuming I want to follow this advice, which again makes sense to me, where would I find such wire to give to my electrician?
To chime in on an update. I’ve since engaged @kingrex ’s services to spec out my AC lines and other fixes for my electrician to follow. Rex has been doing this for years and as he said above, I’ve since learned that it goes way, way beyond just the gauge of the wire… Here is what Michael Fremer of Stereophile said about Rex working with Garth Powell of Audioquest, when they and others joined forces to resolve Michael Fremer’s AC issues:

I have two dedicated lines put in 20 years apart. Congratulations. You will be very happy. I have never heard of an instance of this not helping. I never thought about direct line breakin… but my system has improved over time… so maybe that was why. You will notice an immediate improvement… so, I would just enjoy it and not worry about it. it is not as if you will have anything to compare it to. |
