Dedicated 20 Amp Line for Audio

As my Audiophile friend electrician stated ,and Proved that a 4 wire ,

dual ground is very important one common ,the other a insulated isolated ground 

and preferred awg 11 or 10 li have awg10 Copper , even lower resistance 

and I use Pangea top gold Copper outlets, not a big name brand but very well built.

and less then $100 each.

OK, here’s what I got so far:

I can run one circuit or two, or three, or four, or five, or six, either way.

One line for digital and one for analog, but for the current draw of most audio systems, one should suffice.

Every wire brings RFI into the line, but there’s no RFI’s here.

10 gauge wire for 20 amp circuit, 12 gauge wire for 20 amp circuit, but if you don’t want to hurt your hands, 14 gauge wire for 15 amp circuit.

12/3 - 12/2 (fortunately, I know the difference).

hilde45 & auxinput - completely over the top!

I didn’t ask about power cables or power conditioners?

Metal sheathed wire is ok but so is Romex 14/2, 12/2, 12/3 or 10/2.

Run conduit.

Wait, that is all wrong! I need cryo- Romex, now what size was it?

Great video, crapola video

Heck, if I had chickens to feed they’d all be dead from starvation. No time to feed ’em, let alone watch the Fremer video (yet).

I’m confused

Easy fix.. find a licensed electrician with years of knowledge. Then you won't have to wade through piles of miss guided and silly information.

I've almost finished revising my system with additional lines of #8 wire.

One line is for digital ( CD & DAC ), another for the woofer amps & subs and one line for everything else.

Each AC line has its own dedicated PS Audio power plant. 

A question I would ask is what amp are you using?  Difference between a 8 watt tube and a 500 watt ss can determine if you want to go with 14g

My advice is 12/2 (likely will not hurt your hands) and will cover all amps

RFI is everywhere (if you are on planet Earth that is lol)

If you have 6 open legs in your breaker box make sure your box is not oversized for your line into the house.
