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.

@emergingsoul

I’m beginning to think you are just pulling my chain here...🤔

Where does the power that feeds your house come from?

A Utility Power Company?... Somewhere outside your House there is a step down power transformer that feeds power to the electrical service of your house...

Without a Single Phase 120/240V SPLIT PHASE power system there would be no 3 wire single phase multiwire branch circuit... Can’t have a 3 wire multiwire branch circuit without a split phase power system. The Utility Power Company’s step down power transformer’s center tapped 240V secondary winding is what creates the 120/240 split phase power system.

You asked Why?

Not sure why this would be happening.

jea48,

You say that, Zero amps will return on the shared neutral conductor to the source).

Not sure why this would be happening. And then from this point on in your response above I sort of lose an understanding of what you’re saying.

But I’m really trying to follow. And I think for many it would be nice to know the rationale here as well, as this is a very profound issue.

A multiwire branch circuit is basically an extension of the split phase winding of the utility power transformer.

Most all of us are at the mercy of a 240 V system, that involves step down transformer’s,etc.

We all have a panel in our house with busbars that feed the individual circuits. And there are two legs of 120v power distribution along the bus bars alternating between the circuit breaker’s.

Now is the issue here, jea48, that the Multi branch circuit involves two legs?? Versus the same leg, which isn't allowed with a multi branch circuit.

It seems you’re being more profound by raising issues with the overall power in flow into a house. By design we all live with that.

I am focused on 2 hot wires coming from the panel to support 2 outlets and then the shared returns related to a neutral wire and a ground wire. To this point I haven’t heard any direct problems with this issue. Only in a very broad context dealing with the overall power supply into the house.

So the question becomes, dedicated versus multi branch circuit, is this a problem? To say it’s not isolated is not answering the question as to why it’s a problem. Each of the outlets receives dedicated power off the bus bar. This is a fact.

My question focused on noise which is the issue. And if there’s no noise coming from the neutral, and the ground, assuming these are connected correctly at the panel, and the panel secures the ground via a stake in the dirt, what is the problem??

  1. I agree jea48 has gone out his way. Since you don’t see a problem with a multi branch circuit go ahead and install it then.Problem solved. Or you could use some noise filters. http://v2.stereotimes.com/post/puron-ac-power-conditioner-by-greg-voth/
