New electrical wiring specifications

@digitaljoseph, see here

@rick_n, It has worked out great for me! Money well spent.

@skyy92677,

Maybe a cable TV line, a ground loop isolator might fix that! See here

I have installed a new electrical panel and am going to run 3 dedicated circuits to my audio wall. (40 feet).  2 monoblocks and other components Would like recommendations as to specifications for the electrician as to wire size and type, grounding, receptacles , etc etc etc.   thanks

Dedicated audio lines I would go with Type MC Galvanized Steel Metal Clad Cable 10/2 with insulated ground. It has better EMI and EF shielding versus Non Metallic cable. Receptacles Hubbell see here. 

For what it’s worth category, I would run four dedicated branch circuits for audio only. One for each mono amp, one for analog and one for digital.

@dhite71, I would run the Audio Research REF 160M mono amps with each one on a dedicated 20 amp branch circuit and 10 AWG wire. With the amps plugged directly into the wall.

Appreciate the advice.  Would there be any disadvantages of having those two amp circuits sharing the ground & neutral wires by using 10/3 cable and breaking the connector tab on the receptacle?  

Yes. In my opinion, it will create more noise on the line. Running four dedicated branch circuits is not much more $ then running one when you factor in the cost of your amps and audio equipment. 😎

A true dedicated branch circuit does not share a neutral, hot or ground with any other branch circuits.
