you are correct, milt.
but now we have passed into what is possible and what is safe.

The situation in post #53 is covered in the NEC so is that possible or safe?

What situation in post #60 is not safe?

Say you have a workshop 50 feet away and you want a series of 115 receptacles down two walls where each wall requires a 20 amp breaker. You would put a two pole breaker in the box (supposed to at least), run red, black and white wires the 50 feet and then parallel the neutral to each wall. Even when each leg is drawing 20 amps (40 total) there will never be more than 20 in the neutral.

I expect with the price of copper you will see more of this.
That would be the 230 volts option I suggested. Two poles is 230 volts.

No that would be 2 - 115 volt receptacle strings.

All I was saying to the original poster is this situation may exist. It surprised me when I found it.

Why is this so difficult? Of course Rick is correct, but one could wire that differently and have 230v. One could even wire a 230v machine with those wires and have a 120v light for the work. No additional wires needed.

Well, just to be perfectly clear, you would need 2 additional wires only between the devices if you want 230 at each location. But, I digress.

Because some of us are engineers and some aren't. I'm done, I bought this was obvious, I guess it isn't.
