Wiring 2 outlets to 2 dedicated 20 amp circuits with a single 10/3 electrical wire.
Here's an idea (and it is code compliant), using one 10/3 romex electrical wire (three insulated conductors, and a bare ground wire - 10 gauge), you can wire two outlets to a double pole breaker (and yes the legs would not be the same, which on a quiet electrical system is not a big deal).
In this situation, 2 hot wires from the outlets would be wired directly to each of the circuit breakers, the neutral would be bridged between the two outlets and then connected to the appropriate spot on the panel, and the grounds for each outlet would be attached to the single ground wire that goes back to the panel. This would all appear within a quad outlet wall panel (ie. Two 20 amp outlets side-by-side)
For a long 70 foot run this seems prudent thing to do, less costly and kosher.
Why do you need all these outlets when you have a massive power plant? Or maybe these are related to other areas. Personally I don't like duplex outlets for stuff you don't really need them for, but maybe this is to reduce the size of the electrical wire jungle. Also saw on your system that you are using both an M scaler and a chord dave? Didn't know this was a good pairing.

@emergingsoul @carlsbad this is what my electrician did as well. Works great for me. One circuit for the digital front end, the other circuit for the preamp and monoblocs. About 55' - 60' from the circuit panel to my audio outlet. |
I have both a AV system and a 2 channel system. I have lots of external linear power supplies. The stack of three on the left is now 4. Plus one red one under the right side. I have every port in my PP connected to a 2 channel sound component. I have the AV system plugged into the wall. It is always nice to have the wall outlets handy to plug in temporary things. It just made sense to me to put in the large number of outlets. I would feel silly putting in a dedicated outlet and then plugging a best buy power strip into it to power wall warts.

Don’t do it! Are you trying to save money on the wiring and installation? Not a good place to cut costs.
I can’t believe the number of posts I have read lately where audiophiles have used, or are considering using, this type of wiring method to feed their audio equipment. The reason for a multiwire branch circuit is save money. Period! There may be 10s of thousands of dollars in audio equipment involved and the user chooses to save a few bucks by using this type of branch circuit wiring. Sorry, I just don’t get it... Each Hot, (Ungrounded Conductor), must be connected to breakers fed from both Lines, legs, in the same electrical panel. Therein 240V between Lines, legs. (The 2 Hot conductors cannot be connected to breakers on the same Line, leg.) Both breakers must be tied together with an Approved Listed tie to simultaneously open both breaker with one handle action. (A 2 pole breaker meets this NEC requirement. (New NEC 2008 requirement) . Here is a YouTube video on multiwire branch circuits. LOL, sometime Mike Holt comes off a little like an air head but he is far from that. Holt is one of the members of NEC Code Making Panel. He’s one of many people that helps write the NEC... |
