On one leg or two legs?

Thanks for all replies. I installed the wire bought at Home Depot and it is CAROL Brand. it has four stranded 10 awg conductors, and very flexible. I used two wires for hot on each receptacle and share the ground and neutral. I then installed two breakers on each leg of the panel.

You have two separate circuits..... Not two dedicated circuits. Shared neutral for audio equipment is a bad idea....

There is a noise coming from the outlet (either one) when i plug Virtual Dynamic pc from the outltet to my ps audio PP. I checked the VD PC porarity and found it is correct. I even tried different VD pc and the result is the same. On the other hand the cheapy pc is ok, no noise.

Obviously you did not hire an electrician to do the job. Outlets should not make noises....

I would turn off the two circuits at the breakers and hire an electrician.
.

Are they on the same leg of the main power....(i.e. did you skip a breaker when you installed your new wire?

Why did you share the ground...that's something that only electricians use to save money on cable and to avoid having to pull multiple cables. Sharing the ground is OK (you want all the grounds coming to an outlet box to be grounded at the outlet box, but you should be running separate neutrals for each line back to the main power distribution box.

Ghstudio,
You need to reread Houstonreef's post.....
Because of the wiring configuration he chose he has to have each hot wire, of the multi wire branch circuit, on opposite legs. Both hots share the same neutral, the two hots have to be fed from opposite legs. It's the nature of the beast....

Houstonreef,
Does the wire you bought look like
this?

Jea48,

Yes, That is the wire.

I think i have to hire an electrictian to redo the whole thing. What kind of wire do you recommend?
