Material Specifications/Layout for AC line

Hey Sean or Ernie,

One more question if you don't mind. With my three dedicated circuits, I have the preamp (20 amp) circuit and the digital components circuit (20 amp) on one side of my panel and my amp circuit (30amp breaker) on the other side. Is this correct or should I have all three circuits on the same side?

Same side is preferred. The side with less noisy household items on it.

I'd try both, with an eye toward separating digital from analog (esp preamp), if possible, keeping in mind Lak's comment above.

Tim, don't know how i missed this thread for this long, but i just stumbled across it now. Didn't mean to leave you hanging and i wasn't avoiding you either. Just one of those things.

You've gotten good advice so far, so check into getting everything on one side of the box if possible. Larry's suggestion as to trying to connect to the side with the least amount of household appliances ( refrigerator, heater, washer & dryer, etc... ) is worth checking into also. The use of parallel line filters may also help you without having to install anything between the AC outlet and your components. Sean

Beatlebum/Tim,

Looks like I might be too late in this thread but I'll put in my 2 cents FWIW:
I used 10AWG romex in-wall wire. After reading a # of threads on A'gon w/ really good info from people like Lak to name just 1 person, by 2nd-hand living what Hbrandt went thru about the same time as I did getting dedicated lines, I decided that boutique in-wall wire was not going to be my pancea hence my choice in romex.
Junction boxes are bakelite & there is no metal conduit carrying the wire to my room => no antenna putting crud on my ground wire! When the electrician was doing the wiring in the main panel, I found that ground & neutral are connected to the same bus! He said that this is normally how it done for homes everywhere in the USA & that only for commercial ops do they separate ground & neutral. I believe that older houses have a water pipe ground connection (which I don't as my house is newer. I must be having a copper-rod-stuck-in-the-Earth ground(?) ).
From Bob Crump's suggestion on AA, I decided to try out romex wire orientation! I found it to make a difference even though it was more on the subtle side. I found that romex run one way had a bigger & deeper soundstage vs. romex run the other way. Of course, this is system dependent so the orientation that works for me might/might not work for you. Anyway, orientation made a diff. for me (contrary to my disbelief when I read Crump's post) & I had the electrician run the wires my preferred way.
The RGPC 400S provides internal parallel AC filtering that benefits my source components & my pre (which doesn't seem to need it as much as Ken S. has put in parallel filtering of his own in the power supply box).
I'm using Pass & Seymour 5362A cryo's outlets from Chris Venhaus with excellent results. The "A" designator in the model # is paramount as that signifies an all-brass Olin #688 construction.
I would have loved to use an isolation xformer like many here are using but the Internal Affairs Secretary @ home would have raised 2 eye-brows @ the cost! W/o the isolation xformer, the cost slipped under her radar! ;-)
