You can get 10-4 romex now if you only want to pull one wire or for whatever reason you want to do that , gives you four conductors and a neutral. Still have to share the ground.
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.

Jea48 The comments you make are probably clear to some but not me. Are you saying that the neutral sharing back to the panel is a problem? And if so maybe it's unclear to me why this is. Not sure I follow the rationale about Power supplies of components sharing in this situation. Where is the Sharing coming from? Truth be known, I specifically directed the electrician to create two dedicated lines on the same leg, and then he pulled this crap and I had to live with it. And having considered what he did, I'm trying to understand whether I should rip it all out and have it redone by someone else. His proposal was unclear but we discussed it and then he comes and starts doing the work and I see one wire coming out of the wall and I ask what the heck is going on. The project didn't go very well. They did manage to install one dedicated circuit elsewhere. I couldn't get a second dedicated in the elsewhere room because I ran out of room on the panel. |

It’s more than that. It’s the way a multiwire branch circuit works. I have been trying to find this Web Link for the last couple of days. It was in my Bookmarks but I must of accidentally deleted over the years. Anyway try to follow what is said. Stop when you reach "Three Phase Power Systems" ... A multiwire branch circuit is merely an extension of the split phase winding of the utility power transformer. https://www.ibiblio.org/kuphaldt/electricCircuits/AC/AC_10.html
I believe it... Some electricians just don’t listen.
You could install a Tandem breaker. Tandem Breakers - Circuit Breakers - The Home Depot.

Bad Idea...
A true dedicated branch circuit has a dedicated, Hot conductor, neutral conductor, and equipment grounding conductor. A true dedicated branch circuit does not share a raceway, (conduit), or cable with other branch circuits. An Overview of Audio System Grounding and InterfacingSe page 16. Read pages 31 thru 37.

A true dedicated branch circuit does not share a raceway, (conduit), or cable with other branch circuits. Current carrying conductors from one branch circuit can induce a voltage on the conductors of the other circuit. Therein if there is noise on one circuit it could be induced onto the other circuit. . |
